SUNSET: 
Off Year for the Perseid Meteor Shower
The year's best-known display of shooting stars is usually dramatic and dependable. But even though light from a full Moon will wash out the fainter arrivals when the shower peaks early in the morning of August 13th, you'll still see the shower's brightest meteors streak across the sky.

This week the Sun is putting on its best show in nearly a decade.

This is your last chance to spot Saturn before it sinks into the evening twilight. But there are many other celestial attractions to look for on August evenings.
Watch a Star Wink Out on September 3rd

Rare Occultation by a Double Asteroid
Early on Tuesday, July 19th, lucky observers along a 120-mile-wide path from north-central California to central Saskatchewan have a chance to watch a big, enigmatic double asteroid briefly cover a relatively bright star in Aquarius.
Even if you're nowhere near the path, one enterprising observer plans a live webcast of the view through his telescopes during the event.
Neptune in Motion
Sky and Telescope's editor Sean Walker puts together NASA's anniversary images of Neptune to create a movie that shows a day on the blue planet.
Happy Birthday, Neptune!

For a while, it seemed possible that the asteroid that will buzz Earth on Monday is actually the upper stage of a rocket.
Asteroid To Buzz Earth Monday, June 27th
Asteroid 2011 MD is expected to pass less than 8,000 miles above Earth's surface around 1 p.m. EDT (17:00 UT) on Monday.

A Comet Worth Waiting For?
Observers using the automated Pan-STARRS 1 telescope in Hawaii have found a new comet. As of right now, it might brighten to 1st magnitude in early 2013, but it's far too early to be certain of that.

Supernova Erupts in Whirlpool Galaxy
Supernova 2011dh in M51 seems just past its peak at around magnitude 12.7. With the Moon now gone from the evening sky, the next clear nights are your best chance. It should be visible through an 8-inch telescope in any but the worst skies.
