I am surprised by the number of satellites seen - more than I would see at 1-power? The first three I set out to identify, 20:58 below theta Aql (a CZ-3A), 01:28 flaring in square of Peg (Milstar 3) and 03:38 Cas to Ari (Lacrosse 4) were really easy. A bright one is visible 21:27:28 to 21:34:35 USA 186 is seen only in two images(?) 22:15 Since they show a systematic motion in consecutive images they are not meteors (00:34 looks like a Perseid fireball though). Of course they might be birds/balloons (but not enough lighting on them?) or aircraft (23:30?), but the ones that flare or vary considerably are certain. Lacrosse 4 was almost steady from horizon to horizon. I am intrigued by the number of sats hours around midnight! I concur with the +6 mag star limit, but since a satellite moves only a few pixels in 10 seconds in a fish-eye view, the mag loss is not as significant as in a normal or telephoto/CCD image. The CZ-3A moved about 60 pixels in 120 seconds around culmination, ie 5 pixels/image, so the magnitude loss might be only 1.5 mag at this speed (10 deg/min) I am eager to see how many GEOs it will capture in the flaring geosat season late Sep-early Oct ! /Björn ----- Original Message ----- ... >> >>Here is a link to the evening/morning of 12-13 August (local).
