Interesting object filmed in Germany by Sirko Molau. 5 degrees/second would match a decay indeed, although OIG does not give any likely candidates. Movie (see URL's in below message) is very nice! - Marco ----- Original Message ----- From: "Sirko Molau" <sirko@molau.de> To: "IMO-News mailing list" <imo-news@yahoogroups.com>; "Meteorobs mailing list" <meteorobs@meteorobs.org> Sent: Tuesday, October 19, 2004 10:08 PM Subject: (meteorobs) spectacular meteor recorded > Folks, > > on October 17, 2004, at 02:06:39 UT, my camera AVIS2 captured one of the most > spectacular meteors I ever saw.
