What these numbers mean: http://www.satobs.org/position/IODformat.html ------------------------------------------------------------------------- Conditions were less than perfect (thin haze in the sky), but I managed to recover one of the two May 3rd geostationary UNID's. While in terms of longitude it is close to the UNID-I of May 3rd, I actually believe it is UNID-II (the flaring one), drifted more westward. The brightness behaviour is similar (brightly flaring with a ~1 minute period, see table below), and the declination is slowly changing (UNID-I was stable in declination on May 3rd). I could not positively identify UNID-I on my images: this was very likely due to the poor observing conditions. I have Intelsat 12 and Galaxy 27 on my images only intermittently, and at the edge of detection (see two positions above, from an image that shows them best). I took a series of images between 21:03:00 and 21:14:30 UTC (May 4th), in a semi 30 second interval. The UNID is flashing with a semi 1 minute period, meaning it is typically present on image 1, absent on image 2, present on image 1 etc. Images where it is visible (with some brightness variation: sometimes very bright, sometimes fainter): from - to (UTC, May 4th) --------------------------- 21:03:02.30 - 21:03:12.35 21:04:02.30 - 21:04:12.35 - very bright 21:05:02.30 - 21:05:12.35 21:07:32.30 - 21:07:42.35 21:08:02.30 - 21:08:12.35 21:08:32.30 - 21:08:42.35 - very bright 21:11:02.30 - 21:11:12.35 21:12:02.30 - 21:12:12.35 21:13:02.30 - 21:13:12.35 - very bright 21:14:02.30 - 21:14:12.35 - very bright - Marco ----- Dr Marco Langbroek - SatTrackCam Leiden, the Netherlands. e-mail: sattrackcam@wanadoo.nl Cospar 4353 (Leiden): 52.15412 N, 4.49081 E (WGS84), +0 m ASL Cospar 4354 (De Wilck): 52.11685 N, 4.56016 E (WGS84), -2 m ASL SatTrackCam: http://home.wanadoo.nl/marco.langbroek/satcam.html Station (b)log: http://sattrackcam.blogspot.com ----- _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
