It was twilight in our area (Western New York state) and there were no other stars visible in the sky which was clear. He'd been watching this thing for 15-20 minutes. So, the time frame is from about 8:20 p.m. (Eastern time) to about 8:45 p.m. He asked if it was Venus. I replied that it couldn't be because Venus was below the horizon. I went outside to look and readily saw what he was watching. Then I went back inside, grabbed my binocs, and had a quick look at it before it faded from view altogether.
Nearest I can tell is that this star was in the vicinity of Psi Ursa Major high in the northeast. It did not move so we ruled out aircraft. From the quick look I got through my binoculars before it faded, I thought I detected what looked to be small wisps of smoke very near the object. Anyway, this thing was quite bright - I'd estimate its magnitude to be brighter than Saturn currently, but a bit dimmer than Jupiter. Note that this was in a still fairly bright sky in which I could see no other stars yet.
Could it have been a variable star? Or a supernova? I ruled out meteors and falling space junk since the light was steady and stationary. I don't think it could be an iridium flare since I understand they don't flare for 15 to 20 minutes.
Any guesses, folks??  |
Hi Bluefire,
Jeez the only explanation that I can come up is that you managed to see the setting Sun, light up a Geosynchronous satellite.
I can only come to this conclusion due to three observations you made.
1) the object appeared almost overhead.
2) at twilight or after the sun has set in your horizon, any satellite in geosynchronous orbit, almost directly above you, may have just possibly reflected the setting suns light.
3) the object you observed from two different although close baselines did not appear to move after quite a while of observation.
I haven't checked Mercury's Position, and anyway that couldn't be what you saw.
It sounds like its too far away from the Sun to be the cause, have you checked the Heavens Above web site to see what satellite could have been in that position at that time?
Dennis.
