I have just photographed the “Summer Triangle” from my driveway, using a Canon DSLR camera. The three stars are low in the East, so we can rejoice.. summer has arrived!
The “Summer Triangle” is a startling asterism of three bright stars. Even non-astronomers notice this prominent triangle pattern, during the Northern hemisphere summer.
The star pattern is made more noticeable by the generally light sky at this time of year (it doesn’t get properly “nautical” dark, if you are more than about 52 degrees of latitude North).
I have enhanced the image below, by drawing the “triangle sides”. Hopefully, this will help you to spot the Summer Triangle, when you look up at this time of year. (Ignore the aeroplane trail!)
Enjoy the summer!
The stars are Deneb in the constellation of Cygnus, Vega in Lyra and Altair in Aquila.
