Raduga 27 = 91- 14 A = 21132 ---------------------------- Hello all, on the BWGS web pages Tristan put a graph of the evolution of the flashing period of this Raduga during 1999 and 2000 (PPAS 10). see : http://users.skynet.be/satimage/bwgs/kj/gorizont.htm This object is drifting around the earth very slowly, it takes about 15 years or so to go around... Just like the three Gorizont on the page, this one has also periodical flashing period changes : accelerating and slowing down again. Although Radugas look pretty similar as Gorizonts (cylinder with some symmetrical extended solar arrays), the acceleration of Raduga 27 seems NOT to be linked with the sun : Observations of the last month by Leo and me even confirm that the changes are not seasonally linked. Because this object wasn't observed regularly between 2000 and now, it is not clear what the real period of the periodical variations is. During the same period three years ago, the rotation was slowing down, but currently it is accelerating pretty fast (roughly the period goes down linearly 0.1 second a day). Currently it is flashing brighter than +7 from Belgium/The Netherlands (and probably from other places over Europe/Africa) somewhere between 18h30m and 21h30 UT. Bjoern tried during the same time but didn't saw anything bright. 02-12-26 21:40 KJ 70.1 (only three flashes seen, clouds) 03-01-04 21:14 KJ 69.33 03-01-04 21:23 LB 69.34 03-01-08 19;24 KJ 68.91 03-01-08 20:10 KJ 68.91 03-01-08 20:36 LB 68.91 03-01-10 20:18 LB 68.67 regards, Kurt ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www.satellite.eu.org/seesat/seesatindex.html
