FRIDAY, FEBRUARY 24

■ After dinnertime at this time of year, five carnivore constellations rise upright in a row from the northeast to south, as if out of hibernation. They're all seen in profile with their noses pointed up and their feet (if any) to the right. They are Ursa Major the Big Bear in the northeast (with the Big Dipper as its brightest part), Leo the Lion in the east, dim Hydra the Sea Serpent in the southeast, Canis Minor the Little Dog higher in the south-southeast, and bright Canis Major the Big Dog in the south.

SATURDAY, FEBRUARY 25

■ It's not spring for another 3½ weeks, but the Spring Star Arcturus seems eager to thrust itself into view. It rises above the east-northeast horizon around 9 or 10 p.m. now depending on your location.

To see where to watch for it to rise, find the Big Dipper as soon as the stars come out; it's high in the northeast. Follow the curve of its handle down and around to the lower right by a little more than a Dipper-length. That's the spot on the horizon to watch.

Atmospheric extinction keeps Arcturus rather dim when it rises. But soon it dominates the low eastern sky.

SUNDAY, FEBRUARY 26

■ First-quarter Moon (exactly first quarter at 3:06 a.m. tonight EST). This evening the Moon shines between Aldebaran and the Pleiades, as shown below. Mars is off to the Moon's left.

First-quarter Moon passing the Pleiades, Aldebaran, and Mars, Feb. 26-27, 2023
A first-quarter Moon in late February is always in Taurus. (The Moon is shown here three times its actual apparent size.)

MONDAY, FEBRUARY 27

■ The Moon shines just a degree or two from Mars tonight, as shown above. Watch their separation change hour by hour. The Moon occults Mars for parts of the Arctic.

■ Spot the big, bright, equilateral Winter Triangle in the south-southeast. Sirius is its brightest and lowest star. Betelgeuse is above Sirius by about two fists at arm's length. Left of them shines Procyon.

TUESDAY, FEBRUARY 28

■ February has been Orion's month to stand at his highest in the south in early evening. Now the approach of March pushes Orion westward and brings his dog, Canis Major sporting Sirius on his chest, onto the meridian.

Sirius is not only the brightest star in our sky after the Sun, it's also the closest naked-eye star after the sun, at 8.6 light-years, for those of us at mid-northern latitudes. That makes Sirius the closest naked-eye object for us after Saturn (or yes, maybe Uranus if your sky is very dark).

Alpha Centauri is the actual closest star at 4.3 light-years, but you have to be farther south to see it. And in the northern sky three dim red dwarfs are closer than Sirius, but these require binoculars or a telescope.

Want to try for Sirius B, the famous white dwarf? This year Sirius A and B are at their widest apparent separation in their 50-year orbit: 11.3 arcseconds apart. They will remain at essentially this separation for the next few years before they start closing up again. You'll want at least an 8- to 12-inch scope, a night of really, really excellent seeing (keep checking night after night), Sirius standing at its very highest near the meridian (in early evening now), and the Sirius-B hunting tips in Bob King's article Sirius B – A New Pup in My Life.

The Pup is east-northeast of the Dog Star and 10 magnitudes fainter: one ten-thousandth as bright. As Bob recommends, put a homemade occulting bar across your eyepiece's field stop: a tiny strip of aluminum foil held with a bit of tape, with one edge at the center of the field. Nudge the edge of the strip into sharp focus with a pencil point as you hold the eyepiece up to a light and look through it. In the telescope, rotate the eyepiece to hide blinding Sirius A just behind the strip's east-northeastern edge.

Even with an occulting bar, Sirius B has been undetectable in my 12.5-inch f/6 reflector on all but the very, very steadiest nights.

And the farther south you are the better, because Sirius will be higher when it's crossing the meridian. I'm in Massachusetts at 42° north latitude, so. . . yeah.

Don't worry about moonlight; the glare of Sirius A is much more the problem.

WEDNESDAY, MARCH 1

Venus and Jupiter reach conjunction. They shine in the west during and just after dusk, as shown below. Try taking pictures! Rest your camera on something solid to keep it still during time exposures.

Although they certainly look close together, Venus tonight is 11 light-minutes from Earth while Jupiter is 48 light-minutes away, more than four times farther.

Venus-Jupiter conjunction in twilight, March 1, 2023
Conjunction. This evening the two brightest planets appear separated by only about the width of a chopstick held at arm's length. Their placement in this scene is, as always, exact for skywatchers at latitude 40° north, longitude 90° west, a point near the middle of North America weighted by population. The farther you are from there, the more the planets' orientation in twilight will differ.

THURSDAY, MARCH 2

■ Now Jupiter and Venus have separated to shine 1° apart at dusk.

■ Then as night deepens, the Moon shines a couple degrees from Pollux. Castor looks on from nearby.

FRIDAY, MARCH 3

■ Venus is above Jupiter at dusk, more or less as shown below. They're now 2° apart.

Venus shines close over Jupiter at dusk, March 3, 2023
Venus shines 2° over Jupiter, twice as far apart as they were yesterday and four times as far apart as on the 1st.

SATURDAY, MARCH 4

■ Looking on the other side of the sky to the east, the bright waxing gibbous Moon forms a tall isosceles triangle with Regulus and orange Gamma Leonis (Algieba), as shown below.

Moon crossing Leo, March 4-7, 2023
For the last year, the Moon has formed isosceles triangles (or nearly so) with Regulus and orange Gamma Leonis when passing them every month. On Sunday evening March 5th, the triangle is so flat that it's nearly a straight line. It will be much more triangle-like again on the 6th.

SUNDAY, MARCH 5

■ Now the Moon, only a day and a half from full, shines between Regulus and Gamma Leonis. Moonlight too bright for them? Binoculars do the trick. The stars are about 4° and 4½° from the center of the Moon, respectively, less than the width of a typical binocular's field of view.

 


This Week's Planet Roundup

Mercury is hidden deep in the sunrise.

Venus and Jupiter, the two brightest planets, shine close together in the west-southwest at dusk, changing orientation every day. They're magnitudes –3.9 and –2.1, respectively, a five-times difference in brightness.

Jupiter starts the week on top. They pass each other at conjunction on March 1st, when they'll appear just half a degree apart (during twilight for the time zones in the Americas). Thereafter, Venus is the higher one.

Telescopically Venus is a shimmering little gibbous ball, 12 arcseconds in diameter and 86% sunlit. Jupiter is 34 arcseconds wide. That's small for Jupiter; it's nearly on the other side of the solar system from us.

In a telescope Jupiter displays a strikingly dimmer surface brightness than Venus something you wouldn't guess looking with the unaided eye. It's because Jupiter is nearly 7 times farther from the illuminating Sun than Venus is. Jupiter partly makes up for this deficit by its disk currently showing us 5 times as much apparent surface area (number of square arcseconds) as Venus.

Mars, near the horns of Taurus, shines very high toward the southwest in late dusk, almost overhead. It moves lower toward the west as evening grows late. Mars continues to fade, from magnitude +0.3 to +0.4 this week, and it's now only 8 arcseconds wide. That's too small to show visual details in most telescopes most nights, aside from its gibbous shape (90% sunlit, see below) and maybe signs of the North Polar Cap.

Gibbous Mars on Feb. 2, 2023
Receding Mars as imaged on February 2nd by Christopher Go in the Philippines. South here is up. Upper left of center, the most prominent diagonal dark marking is Mare Sirenum. The North Polar Cap has become clearer. A little above it, a small gray patch marks Elysium with thin clouds over and around it. The dark arc just inside the bright limb is partly a processing artifact, but the dark margin of the North Polar Cap at bottom is a known real thing.

Aldebaran shines some 12° below Mars. At magnitude +0.8 it looks more like Mars all the time. They'll match brightnesses right at the turn of spring in about three weeks.

Saturn is buried deep in the sunrise.

Uranus, magnitude 5.8 in Aries, is still observable in the west right after dark. It displays a tiny, very slightly blue-greenish gray disk 3.6 arcseconds wide. It a telescope at high power it's definitely non-stellar. See the Uranus finder charts in the November Sky & Telescope, page 49.

Neptune is lost in the sunset.

Want to become a better astronomer? Learn your way around the constellations. They're the key to locating everything fainter and deeper to hunt with binoculars or a telescope.

This is an outdoor nature hobby. For a more detailed constellation guide covering the whole evening sky, use the big monthly map in the center of each issue of Sky & Telescope, the essential magazine of astronomy.

Once you get a telescope, to put it to good use you'll need a much more detailed, large-scale sky atlas (set of charts). The basic standard is the Pocket Sky Atlas (in either the original or Jumbo Edition), which shows all stars to magnitude 7.6.

Pocket Sky Atlas cover, Jumbo edition
The Pocket Sky Atlas plots 30,796 stars to magnitude 7.6, and hundreds of telescopic galaxies, star clusters, and nebulae among them. Shown here is the Jumbo Edition, which is in hard covers and enlarged for easier reading outdoors by red flashlight. Sample charts. More about the current editions.

Next up is the larger and deeper Sky Atlas 2000.0, plotting stars to magnitude 8.5; nearly three times as many. The next up, once you know your way around, are the even larger Interstellarum atlas (stars to magnitude 9.5) or Uranometria 2000.0 (stars to magnitude 9.75). And be sure to read How to Use a Star Chart with a Telescope. It applies just as much to charts on your phone or tablet as to charts on paper.

You'll also want a good deep-sky guidebook. A beloved old classic is the three-volume Burnham's Celestial Handbook. An impressive more modern one is the big Night Sky Observer's Guide set (2+ volumes) by Kepple and Sanner.

Can a computerized telescope replace charts? Not for beginners, I don't think, and not on mounts and tripods that are less than top-quality mechanically. And as Terence Dickinson and Alan Dyer say in their Backyard Astronomer's Guide, "A full appreciation of the universe cannot come without developing the skills to find things in the sky and understanding how the sky works. This knowledge comes only by spending time under the stars with star maps in hand."

Last night sunset was lovely, waxing crescent Moon, Jupiter, and Venus in Pisces. I did get out enjoy some telescope time. Observed 1730-1830 EST. Sunset 1753 EST. Lovely evening at sunset with waxing crescent Moon, Jupiter, and Venus in Pisces. I viewed naked eye and with 90-mm refractor telescope at 71x using TeleVue 14-mm Delos. There were thermal currents in the atmosphere so some distortion when viewing, earthshine visible on the Moon - more apparent by 1815 EST. Quite a breathtaking sight the bright waxing crescent Moon, Jupiter, and Venus in Pisces. At Jupiter 4 Galilean moons visible (Ganymede, Europa on one side, Io and Callisto the other side), cloud bands and shading visible at the poles. Venus bright gibbous shape apparent too (about 87% illuminated). Jupiter and Venus 01-March-2023 will be about 0.5-degrees apart. The sunset tonight was a lovely sky with this trio in WSW-W. Virtual Moon Atlas shows Moon's angular size 32.12 arcminutes, Stellarium 1.2 shows Jupiter 34.46 arcseconds, and Venus 11.95 arcseconds or about 12 arcsecond angular size. Jupiter and Venus about 6-degrees 15 arcminutes apart, the Moon and Jupiter about 13 degrees 35 arcminutes apart in Pisces (Stellarium 1.2).

I was able to do some solar and lunar observing this morning.

Observed 1100-1200 EST. 5 active sunspot regions viewed this morning on the Sun. Sunspots AR3234 very large area, AR3235, AR3229, AR3236, and AR3230. Various plage regions visible using glass white solar filter at 31x with my 90-mm refractor telescope. Stellarium 1.2 shows 0.990 au for the Sun's distance and at 31x, telescope views resolved to about 9.6 arcsecond on the Sun, about 6893 km diameter. Sunspot AR3234 region is large and spaceweather.com reporting about this sunspot region today. Given what I observed, AR3234 region it could be 1.5-2.0 arcminute angular size on the Sun. In addition to solar observing, I enjoyed some daytime observations of the waxing crescent Moon in Aries. Mare Crisium, along with craters like Macrobius, Cleomedes, Burckhardt, Geminus, Langrenus, and others (Virtual Moon Atlas). The Virtual Moon Atlas reports lunar angular size 31.70 arcminutes. The Sun’s angular size is 32.3 arcminutes according to Stellarium 1.2. At 31x the true FOV was a bit more than 1.5-degrees in the eyepiece (TeleVue 32-mm plossl). Windy conditions so the telescope bounced at times while watching. NW winds 16 knots, gusting 24 knots. I had a fun time in the solar system last night at sunset and this morning.

Great reports! Sounds like the weather is getting nice there and I’m hoping you’re able to see the conjunction on Wednesday. It’s been hit or miss here we had one night that was perfectly clear, when the moon was near Jupiter. Not sure if we’re going to be able to see it tonight clouds ans are rolling in from the south. We were looking at the pretty daytime moon a few hours ago.

How far do you have to go from your house to get to the pasture where you usually do your observing? Is it close enough to walk or do you actually have to drive?

For the pastures at my place, not very far. 100-150 yards to setup from my house so a walk. Today we had some light snow (no accumulation). I will wait and see what happens for 01-Mar conjunction of Jupiter and Venus. Running the woodburning stove today 🙂

I noticed this report after my solar observation this morning. 🙂 People Keep Reporting Seeing Two Suns or a "Rogue Planet" in Sky, https://www.msn.com/en-us/news/technology/people-keep-reporting-seeing-two-suns-or-a-rogue-planet-in-sky/ar-AA17TRyB?ocid=msedgdhp&pc=U531&cvid=36ffdb664e2f4f9fbacc0cc1f921f885&ei=12

Reports like this are amusing. I did see only one Sun in the sky today 🙂 Perhaps my observation skills need to be tuned a bit 🙂

In the comments for last week's "This Week's Sky at a Glance," Misha pointed out that on Monday February 27, the Sun will be at the same declination, 8 degrees south of the celestial equator, as it will be during the October 14 annular solar eclipse. This is an opportunity to see where the eclipse will appear in the sky from your observing location. The Sun will reach the same location in the sky 27 minutes later on February 27 than on October 14.

I figured I'd chime in with the fact that last night (2/24) I also enjoyed seeing the Moon, Jupiter and Venus while out for a short walk in the crisp, cool air, which turned cold today. Like Mary Beth, no such luck tonight here in Central Jersey with the cloud cover. Hopefully better luck tomorrow!

I did enjoy some more telescope time this evening from 1800-2000 EST (my 90-mm refractor telescope). Moon, 37 Tauri, M42, M41, NGC 2362, M35, NGC 2158 I looked at using TeleVue 32-mm plossl at 31x. Some very nice observations and much crater detail along terminator line as the Moon nearly First Quarter (First Quarter Moon 27-Feb-2023 at 0806 UT/0306 EST.) Given the elevation angle of Jupiter and Venus tonight near 1845 EST, the conjunction on 01-Mar-2023 after sunset should be easy to see from my east pasture, weather permitting. Clear skies, temperature 4C. Moonlight across the fields and woods – ethereal sight. At the moment, I may have clouds and some rain later on 01-Mar-2023 that night for the Jupiter and Venus meeting. I will wait and see 🙂

A preview this evening of Jupiter and Venus tomorrow night 🙂

Observed 1730-1830 EST/2230-2330 UT. Some very good views of Jupiter and Venus this evening about 77 arcminutes apart. I used my 90-mm refractor telescope with eyepieces that allowed 25x to 40x views. TeleVue 40-mm plossl (25x), TeleVue 32-mm plossl (31x), and Orion Sirius 25-mm plossl (40x). The #12 Yellow filter allowed for easier viewing of Venus. Bright gibbous shape planet. At Jupiter cloud bands visible and the Galilean moons Ganymede, Io, Europa on one side, Callisto on the other side. Venus was near the 7:00 position in the eyepiece FOV while Jupiter 2:00 position (north up, mirror reverse view). Both planets fit into the FOV at 25x and 31x. Stellarium 1.2 angle measure showed the planets about 77 arcminutes apart tonight. Tomorrow night on 01-March-2023, Jupiter and Venus will be about 0.5-degrees angular separation. Higher power observations will be possible, weather permitting. This Jupiter and Venus close conjunction reminds me of the 04/30/22 close conjunction of the pair, again about 30-arcminutes or 0.5-degrees apart. From my log, morning observation note or 04/30/22. “Observed 0520-0625 EDT/0920-1025 UT. Sunrise 0611 EDT/1011 UT. Spectacular dazzling duo of Venus and Jupiter in Pisces this morning – WoW! Venus 67.42% illuminated; Jupiter 99.53% illuminated. Stellarium 0.22.1 angle mode shows separated by just less than 30 arcminutes (29 arcminute, 47 arcsecond at 0545 EDT).” Now I am enjoying another conjunction of Venus and Jupiter in Pisces Skies clear, temperature 7C, winds 360/7 knots.

Hello Rod I’m so happy to hear you got to enjoy Conjunction Eve! Great, you have your notes to look back on from last year. I remember you said last week he thought the weather might be bad Wednesday. Really hoping that report was wrong and you will have clear skies tomorrow night!

It was cloudy at sunset, but fortunately by 7:45 PM it cleared off very nicely, and we were able to look at the planets. I think we’ve only missed seeing them one night this week, even if it was two clouds, we were able to observe the distance.

The Moon and Mars were beautiful Monday night. I watched the moon until it got too low to see over the rooftops, very enjoyable show!

Okay, a conjunction of Jupiter and Venus did I see this evening. 🙂

Observed 1745-1845 EST (2245-2345 UT). Waxing gibbous Moon in Gemini. Sunset near 1759 EST. Jupiter and Venus conjunction this evening, very lovely, a dazzling pair in the sky by 1820 EST. Stellarium angle measure showed 32 arcminutes apart. I used my 90-mm refractor telescope with TeleVue 14-mm Delos and TeleVue 9-mm Nagler for 71x and 111x observations. At 71x with a true FOV a bit more than 1-degree, both easy to see in the FOV. A bit more difficult at 111x to see both but I could (true FOV about 44 arcminutes). Venus, distinct gibbous shaped planet and bright (85.6% illuminated and 12 arcsecond size). Jupiter (34 arcsecond size and 99.7% illuminated) cloud bands, shading at the poles distinct. The Great Red Spot was visible. The GRS transit time tonight was 02-March-2023 at 0025 UT/1925 EST 01-March-2023. Europa occultation by Jupiter at 2318 UT. I did observe Europa until Europa disappeared behind Jupiter's limb. Io, Callisto, and Ganymede visible on the other side. The March 2023 Sky & Telescope magazine, pages 50-51 supplied tables for GRS transit times and Galilean moon events at Jupiter. While viewing this evening, several flocks of geese were migrating north flying over my location, in the V shape flight school pattern, honking loudly . Time to move north to nesting grounds. Clear skies this evening at sunset, some high cirrus. Temperature 7C, winds south 6 knots. A pleasant time at sunset watching Jupiter and Venus conjunction in Pisces.

To me, the conjunction resembled a much brighter version of the "Cat's Eyes" in "the Sting" of Scorpius.
Very beautiful but a little creepy to have 2 eyes staring at me.

I'm reminded of the optometrist's billboard from "The Great Gatsby'
( Google search results: https://www.google.com/search?q=the+great+gatsby+billboard+eyes&sxsrf=AJOqlzWNg3N2kBozoXLw-usWZ2BOXTHbgg:1677728988861&source=lnms&tbm=isch&sa=X&ved=2ahUKEwiN66PDq7z9AhUukWoFHVoCBbsQ_AUoAXoECAEQAw&biw=1366&bih=657&dpr=1 )

... Finished off my evening viewing watching Canopus culminate due South around 7:40pm here in Los Angeles. I have about maybe 2 more weeks before it culminates in strong evening twillight as it occurs 4 minutes earlier each night while sunset occurs later each night.

I noticed that light pollution has gotten very bad in recent years. Canopus was easily visible tonight if you knew when and where to look, but the skies were clear, cold and dry after the recent rains. Any sort of haze, compined with the city lights, would "wash out" my southern horizon.

As it is, 2 hours after sunset, the sky is not black but still very deep blue, like late twilight or the night sky when the moon is almost full. (It's still only just past 1st quarter, and the sky had the same appearance a couple weeks ago when there was no Moon). I can easily see the 1st-magnitude stars, and even the 2nd-magnitude stars in Orion's belt since it passes so high, but the Big Dipper is hard to make even out in the northeast - it's not so near the horizon that atmospheric dimming would be a problem.

Rod so glad you got to see the conjunction under such great conditions! Wonderful description of all sights and sounds you experienced. Geese a nice sideshow! A night to remember for sure.

Clouds here but they parted very briefly at 7:10 p.m., so I did get about a five minute viewing opportunity. Thank goodness I was out watching during that very time, would have missed otherwise even if I’d stayed out until they set.

The sky was a little more hazy tonight, and the light from the waxing gibbous Moon added to the man-made light pollution, but I was able to see Canopus culminate around 7:35pm.

Also, the Moon is/was in conjunction with Pollux tonight, passing 2 degrees south of the star. As the moon's ascending node makes its 18-year passage along the Ecliptic, the location of the moon's maximum celestial latitude (distance from the Ecliptic) currently lies near Pollux. Pollux lies at Right Ascension 7hrs 45minutes, and currently the Moon's ascending node is around Right Ascension 2hr 10min; in mid-August the ascending node will lie 6 hours RA west of Pollux, brining the max celestial latitude closest to the star.

Pollux use to lie close enough to the Ecliptic for the Moon to occult the star, but the shift in the Ecliptic against the stars due to Precession, along with gradual changes in the "tilt" of the Moon's orbit due to gravitational interactions between the Earth and Sun, put Pollux just out of range for occultations. According to the Wikipedia entry for Pollux, the last lunar occultation of the star occurred in the 2nd Century BCE and was only visible from the far Southern Hemisphere.

Aldebaran*, Antares, and the Pleiades lie near the limits for lunar occultations, and their "occultation seasons" last several years as the maximum celestial latitude "lingers" in their vicinities, so the Moon will still be passing close to Pollux for the next couple of years.

* Aldebaran lies so close to the southern limit of lunar occultations that occultations of that star are currently only visible from the Northern Hemisphere and the Tropics, and are not viewable from Australia, southern Africa, southern South America, or Antarctica.
