Tonight's Sky for May 18: True Young Moon



How thin of a Moon have you seen? How about one that's less than a day old and only 2% illuminated? Well, if you have never seen a Moon this thin, tonight's your chance to do so as such a Moon will be making an appearance in this evening's sky just after sunset.

To see the Moon, you'll need a good Northwestern horizon. How good? One with less than 3 degrees of obstruction. To simulate this, hold a little finger out at arm's length to simulate 1 degrees. Hint: if you can't think of a good location off-hand, scout out one during the day. Location found, be there at sunset and start scanning the horizon with your binoculars.

Don't see the Moon right away? Don't panic, as the sky dims, the Moon will get easier to see, which means that it will often just suddenly 'pop' out of the darkness. Believe me, when it does, it's an exhilarating experience.
