Here is an excerpt from my >Seesat post on 3/25: I remember seeing this post now, but hadn't added the object to my observing lists. At least this confirms that Gorizont 24 is also easily observable from Europe also. Yesterday evening I ran a search using Mike McCants "Findsat" programme, then plotted the tracks of satellites which were in the vicinity through Skymap. Now I have a full explaination of what I saw. The first two flashes did in-fact appear south of the TDRS-7Rk track, so this fits with Gorizont 24's position. However at the same time a debris object 670001AE/13910 (not a know flasher) was passing along a WNW->ESE track just to the north of the TDRS7-Rk, so the third flash probably came from this object which led me to beileve that the UNID was moving in a northerly direction (it wasn't case of me mixing up the field orientation after all). As a result I kept this spot fixed in the field of view & missed any further flashes from Gorizont 24 as it was outside of the field of view of my telescope. I still haven't been able to make any follow up observations to to adverse observing conditions. However, both Gorizont 23 & Gorizont 24 are now well placed for European observers. For those observers who have never seen a geosynchronous satellites both of these objects are potentially visible in binoculars, flashing up to mag +5 at least. Gorizont 23 flash period is about 50s, whilst as Rob Matson indicates Gorizont 24 is flashing every 90s. Here are recent elements for both of these objects; GORIZONT 23 1 21533U 91046A 99116.36469887 .00000017 00000-0 10000-3 0 1445 2 21533 4.5603 65.0425 0004945 103.1699 256.8504 0.98905113 22670 GORIZONT 24 1 21759U 91074A 99113.45341774 -.00000018 00000-0 10000-3 0 8110 2 21759 4.2503 65.4330 0014683 2.6538 357.3166 0.98441951 27413 Best wishes & clear skies, Jason P.S. <Off topic> I'm thinking of adding encoders & "digital setting circles" to my dobsonian telescope (eg. like the Meade Magellan 1 system). If anybody has any experience with this kind of setup could you give me some suggestions (e-mail me directly, not to the list the list) on how best to impliment this. --------------------------------- Jason Hatton INSERM U 343 Hopital de l'Archet Rte St. Antoine de Ginestiere BP 79, 06202 Nice Cedex 03 France Tel(33)-4-92-15-77-00 Fax(33)-4-92-15-77-09 email : hatton@unice.fr 43.667N, 7.223E, Alt 30M
