Mark your calendar for February 15-16, when Asteroid DA14 will pass within 10,000-20,000 miles of the surface of the Earth. This is a big asteroid, at 125 feet, and could cause considerable damage if it was to impact. Lucky for us, we will not have anything to worry about. More here from Earth Sky.
Only one eclipse will be of significance for the West Coast, on October 18th when the Moon will pass within the Earth's penumbral shadow. This partial eclipse will start before moonrise in California, but once the Moon rises, should be a nice sight.
Every month as the Moon slips past planets and stars in the night sky, there are moments when a distant object is blocked out by the Moon, called an Occultation. This year there are several close encounters that should be quite fun to watch from the Bay Area. Depending where you are on Earth, you can see more or less of these events. A few noteworthy ones: January 21 and March 17 when the Moon passes very close to Jupiter; and February 28-March 1 and July 15-16 when the Moon passes very close to the bright star Spica.
Be sure to check out the Year In Space calendar for 2013 which has fascinating facts and is a wealth of astronomy information for every day and month of the year. And happy viewing this year!
