Today:
The brightest star in the Summer Triangle, Vega, appears nearly overhead as the last of the twilight fades near 7:30 PM. Vega’s brilliance is due, in part, to its location just 25 light years away, and because it is the fourth brightest star within 50 light years of here. Later this evening, near 9 o’clock, a second star in the Summer Triangle, Deneb, crosses the very top of the sky, the Zenith.

Saturday:
Early tomorrow morning, at around 3:30 AM, a dwindling sliver of the crescent moon will rise in the east-northeast, and within the breast of Leo, The Lion. The Moon will appear just to the left of Regulus, Leo’s brightest star, due east by 5:30 AM, just before the first tendrils of twilight announce the approach of dawn.

Sunday:
With the Crescent Moon now below Leo’s bright star Regulus tomorrow morning from 5 o’clock to sunrise, from 6 to 6:15 AM, look well to the Moon’s lower right, where, just above the horizon, you might see a comet in the twilight, Comet Tsuchinshan-ATLAS, with a faint tail to the upper right. It rounds the Sun, lost in its glare, then reappears in the evenings by October 12th, low in the west-southwest.
