SUNSET: 
Your Lunar Eclipse Pictures
On the night of September 7 – 8, a partial lunar eclipse graced the skies above Europe, Africa, Asia, and Australia. Although the Moon barely entered Earth's umbra (full shadow), plenty of astrophotographers captured the tiny nibble taken out of the edge of Luna.
Chi Cygni's Record-Breaking Maximum
The red, Mira-type variable star Chi Cygni has had a very unusual maximum. It's one of the brightest such variables to begin with (typically peaking at about magnitude 5.2), but in late July and early August 2006, it peaked at about magnitude 3.8.
Earth Bites Moon
On the night of September 7-8, a partial lunar eclipse will be visible in Europe, Africa, Asia, and Australia. On the same night, observers on the west coast of the Americas will see a double shadow transit on Jupiter. Head outdoors and see it for yourself.
Squeezing Out the Last Drops of Summer
The first-quarter Moon shines near Antares in Scorpius tonight. And as the weekend progresses, you can see the growing Moon slide over to the Teapot pattern of Sagittarius. Be sure to capture these constellations before they are gone for the year.
Find the "Dwarf Planets"
The smoke has cleared. Pluto, Ceres, and 2003 UB313 are officially "dwarf planets." And they are all visible to amateurs tonight — if you have the right equipment. Grab your gear and try some "planet" hunting tonight!
Catch a Naked-eye Sunspot
There's a nice big naked-eye spot on the Sun today, even though we're near the minimum of the 11-year sunspot activity cycle. Of course, when we're talking about the Sun, "naked-eye" means looking through a safe solar filter.
The Moon Near the Pleiades
The Moon will be closing in on Messier 45 tomorrow morning; observers in Hawaii will see the Moon pass in front of the star cluster.
Perseids Perform
The reports are in! Despite a waning gibbous Moon on the evening of August 12th, the Perseid meteor shower did not disappoint. Between twilight and moonrise, observers from dark country skies reported up to 20 “shooting stars” an hour — a meteor every three minutes — some fast and blip-like, some slow and spectacular.

This red long-period variable is sometimes visible to the unaided eye — and sometimes invisible even in a 4-inch telescope.
