Target Iridium 5 Flare Constellation Tau Category Satellite Time yyyymmdd.hhmm 20080423.1723 EDT Comments Not Seen Based on my past experience with daylight Iridium flares I hadn't really expected to see this one but gave it a try anyway since it was bright. I sighted the azimuth with my hand bearing compass and estimated the elevation and trained my binocular with an 8° FoV on that area but didn't see anything.   Heavens Above CalSky Time 1723:08 EDT   Alt. 47°   Az. 248° WSW   Mag. -6.5   Surface

The sky looks gray, like impending rain, even though it is clear. There are dissipating showers over in the Poconos, but nothing forecast locally. The air does smell a little moist though.
