What is up Tonight?
(In the event that this page is not up-to-date, skip to the links below for external resources).
Almost everything is "up" tonight, if you're willing to observe from dusk to dawn. We'll list things here that are visible after Sunset and rise within a couple hours afterward.
Note that the Moon is different every night, rising about 50 minutes later (and lying about 15 degrees further east every day). Why does it change?
What's up for the Fall, 2013?
The summer Milky Way is great to browse through with binoculars or a small scope. If you're in a dark, clear sky, that cloudy swath of grey is the Milky Way. Right now, mid-September, the Summer Triangle is overhead at sunset, the Milky Way runs right through it, north-south.
Saturn is heading around the backside of the Sun soon, you might be able to catch it in the low west after sunset. The other bright planets are visible before sunrise.
The sun is up every day and visible from even the brightest, dirtiest sky. Click here for more info on solar observing
Where are you?
The whole sky is up at all times. Everything in it is up everyday. So why can't you see it all at any time? The sun washes out the sky during the day and, of course, the earth gets in the way. The Earth does block out the Sun so that we can see the stars, but it does also block out how far to the south we can see. The closer you get to the equator on earth, the less of the sky is permanently blocked out. From San Diego at 32 degrees North Latitude, we cannot see the sky closer than 32 degrees to the south celestial pole.
