I managed to catch a bright -3 magnitude (-7 at center) Iridium Flare on Saturday night on a camping trip at Lake Dillon to celebrate Father's Day with my in-laws. The flare occurred at 22:53:37 and can be verified by the Heavens Above website Iridium Flare calculator here ( http://www.heavens-above.com/flaredetails.asp?SatID=24869&lat=39.59925&lng=-106.04706&alt=0&loc=Unspecified&TZ=MST&Date=40713.2039039652&Mirror=0 ) .
This is my third Iridium Flare to catch by luck when doing some night photography. For those new to them, Iridium Flares are caused by a constellation of highly reflective communication satellites (Iridium system) that regularly and predictably glint off the sun. See below for other examples from my stream and have a great week ahead!
