Walked onto the porch to let the dogs out before bed and, as is customary for me, looked up to the sky. sighted what appeared to be an often sighted satellite light moving northeast past the handle part of the big dipper. i then noticed a second similar light, staggered to the left of the initial light, going the same direction and speed. i thought this unusual because i never have seen two satellites go through the sky in this manner. while watching i then noticed a third similarly bright light traveling the same direction and speed forming a rough triangular formation. they moved about the same speed as most satellites that go across the sky. one by on there lights seem to fade and blink out after about 30 seconds of observing all the while maintaining the formation. i'm an avid sky watcher and 99.9% can recognize or explain lights in the sky. this one is a first where i'm baffled.
