Thanks Mike! This makes perfectly sense. At the sidereal rate this would cross my field of view in 50 seconds and with 50 dots on screen it has flashed exactly at 1 Hz. Magnitude 8 per flash is perfectly reasonable too if the flash time is very short as it seem to be. Is this some kind of optical beacon or is it there something that rotates this fast? Mystery is solved. arto 2013/8/19 Mike McCants <mmccants@prismnet.com> > Arto Oksanen posted: > > >The image has 50 bright dots in a line across the 12 arc minute field. > > I would assume that you were tracking the sky and that an object > in near-geosynchornous orbit would move through your field of view > during the time of exposure. > > The following object is known to flash to magnitude 8 every 1 or 2 seconds: > > Mentor 1 r > 1 23568U 95022B 13230.36811466 .00000000 00000-0 00000-0 0 09 > 2 23568 13.4751 60.3413 0006347 201.3275 158.6581 1.00543289 606 > > It matches your altitude and azimuth at that time reasonably well. > > Mike McCants > _______________________________________________ > Seesat-l mailing list > http://mailman.satobs.org/mailman/listinfo/seesat-l > -- Arto Oksanen arto.oksanen@jklsirius.fi Muurame, Finland "In a world where I feel so small, I can't stop thinking big." -------------- next part -------------- An HTML attachment was scrubbed...
