SIGHTING: CASCADE (7 MILES NW CITY OF), ID

Witness Testimony

""Star" brightend in shy, then slowly faded away to invisibleWas looking at SW sky approx 15 degrees off horison, just over top of Mtn range in distance. Noticed an airplane traveling west over lake. Turned to talk to someone in house and as I looked back I saw a new very bright "star" in portion of sky I'd been looking at. It was brighter, whiter & larger than the brightest planet you'd expect to see in the sky. As I began to tell the others inside to come look, it grew brighter for second, then over a period of about five seconds grew dimmer and smaller as if it was going out. Or as if it was going directly away a a high rate of speed. I do not know. It went "out" and in that part of the sky I could see other stars that were behind or beside (?) it, but had trouble seeing in it's direct area (very small circle of the sky). All this time the airplane I had seen earlier was traveling across the same aprox line of sight. I do not know what it was. My first thought was a SuperNova which I'm told is a extreme brightening of a star followed by it's dimming and going out. (I'm telling this only to aid in my description, not teach you what a SuperNova is!!) I am college educated, professional, sane , sober, drug free, 43 YO male and believe Im rational."
