triangular light siting in the north east skies over Reno NVI had just finished setting up my 8 inch Celestron telescope and assembling my other night viewing equipment. Celestron Skymaster binoculars and my 10x50 Nikon binoculars.,chairs and multiple wireless devices. I usually allow 30 to 45 minutes for my eyes to adjust to the dark however this event took me bu surprise.As I settled into my seat and started scanning the evening skies out of the dark 3 brilliant glowing white lights suddenly appeared. No slow build in intensity they just appeared.The 3 lights were in the shape of a perfect triangle. One on the top and two forming the bottom line of the triangle. My first thought was how interesting it is that 3 satellites suddenly appeared.I picked up my Nikon binoculars and focused on all 3. As I watched all 3 moved in a uniform pattern and never moved from the triangle shape they appeared in.My best guess is they appeared approximately 25 degrees above the skyline and close to 38 degrees north north east.As the triangle moved to the east the light intensity was consistent and brilliant.I continued to observe the 3 uniform lights for approximately 10 more seconds.By this time the lights rapidly faded to black at around 58 degrees north east.And as quickly as they appeared it's like someone hit the light switch. All 3 disappeared.Mr. Davenport, I perform this ritual nightly and have done so for at least 15 years.I know what satellites look like...I understand the way they move through the night skies and slowly faded out of view as the sun reflection passes.I'm not saying this was a UFO but I am saying I've never seen 3 satellites fly in formation and disappear all at once.Very bizarre event over the Northern skies of Reno NV.Take care sir!
