The Summer Triangle is a magnificent, quite large shape prominent in the summer sky. Here in Baton Rouge one can see it completely above thirty degrees altitude at 10pm CDT from 5 July to 29 October.

The three components are Lyra's A-class Vega (magnitude 0.0), Aquila's A-class Altair (magnitude 0.8) and Cygnus's A-class Deneb (magnitude 1.3).

Here are the lengths of the sides...
Altair to Deneb, 38˚01'
Vega to Altair, 34˚12'
Vega to Deneb, 23˚51'

Tonight, try to see how early you can spot all corners of the Triangle as it's getting dark. Half an hour after sunset? Earlier? Later? The current NOAA forecast indicates the best time to skygaze during this upcoming nighttime period is probably end of twilight to about 11pm, when the relative humidity reaches ninety percent.

The Summer Triangle stands strong and tall tonight at 11pm CDT, with Vega over eighty degrees high. Consider looking tonight while pondering the words of Chet Raymo from his "August 1" entry...
August almost certainly provides the best stargazing of the year. The nights are warm, the stars are bright. The most splendid sweep of the Milky Way arches overhead. And the sky is full of shooting stars. No indoor pleasures, no television superspecials, can compare to a night full of shooting stars.
Of course, "shooting stars" is classic slang for meteors. Well, Baton Rouge at this point has no delights of the Milky Way arch or the dimmest meteors. If we get rid of most of the light pollution, though...

It's that time again--the Summer Triangle test. How soon can you spot all three corners? You should start trying at least by Wednesday evening. Go out around 7:15pm with some iced water and a lawn chair and face east.
