I have a modified webcam with no IR filter connected to my PC and looking upward towards the sky through my office window. I keep it there all the time and watch the skies, clouds etc. using WebCam application.I was just gazing at the WebCam while taking a break this evening around 7:30PM Seattle time and noticed a smooth sailing triangular looking object flying by. It was flying very slow compared to the planes that usually fly by here all the time. I sit close to the window where the camera is and can hear the planes all the times. In this case it was quiet and I couldn't see anything outside through the naked eye but only through the WebCam application connected to my modded camera. I hit the SNAPSHOT button twice on the application to capture the frames, got two. I am attaching the original picture as the camera sees it and then the enhanced one. To me it looks like a triangle of some sort. Have any one of you seen something like this? Is it really a triangle flying. What was unique about this is that it was quiet, smooth slow sailing, no lights as I couldn't find it in the sky but only through the cam. Can't confirm what it is - see the pics and be the judge.
