I measured the end points of the track as 20.757639,+30.717778 and 20.763556,+30.762500 (decimal RA/dec for SkyMap deepsky.txt) and had FirstOrb make a few possible circular orbits on the assumption that it was a flash from a slowly rotating object. Positions in ElCor/First notation: 1 02 11 07 4 42 03.0 20 45.45 30.718 2000 9.9 1 02 11 07 4 42 06.0 20 45.81 30.763 2000 9.9 I got these suggestions: 02-811A track 10.2 seconds 3.2 1 90811U 02811 A 02311.11351505 .00000000 00000-0 00000-0 0 00 2 90811 41.3667 273.1057 0000010 0.0000 0.0000 2.00614778 00 02-811A track 3.0 seconds 5.2 1 90811U 02811 A 02311.16111987 .00000000 00000-0 00000-0 0 00 2 90811 38.8871 272.5577 0000010 0.0000 0.0000 5.95141660 00 There are many eccentric orbits that could also fit. The Westford Needles suggested are almost at right angles to track. Az = 294, alt = 21 degrees. The brightest star in the 4 o'clock position from 52 Cyg is the 8.6 mag HP102468/HD335027 at 20:45:49.32 +30 39' 43".5. (Rotate image about 156 degrees clockwise to get alt/az view) Perhaps a slow glint from a Molniya-type satellite at apogee ? ----- Original Message ----- ... > > http://home.att.net/~astropix/Dan_s_Satellite.html > > The particulars are: > > > The bright star in the center, showing some 'blooming' > > artifacts is 52 Cyg... the trail is just to the left > > and inclined about 15 degrees to the framing of the > > shot.
