     Hi all,


    Yesterday evening my attention was attracted at 18h 40.8 mn UT by a bright satellite near Polaris, challenging its brightness, and descending due North - slightly western to the north, the signature of a retrograde satellite. Its crossing in the sky was about the same as that of Cosmos 405 rocket I just observed a few minutes before (near 18h34 UT).

    However the sense of the pass (SN) was just reversed, as Cosmos 405 rocket (passing NS) is a 81.2 inclined satellite.

    Hence the estimated inclination of the retro satellite is to be roughly i 97-98.

    And it might have culminated  not far from ENE at altitude 72-80.


    Its brightness was increasing and it flared briefly at about mag -1.5 at 18h 41m 02s.


    Thanks for identifying this satellite, not listed in the H-A predictions for my site (listing for mag better than 5.0), since its magnitude must have been indicated as a mere  "?" by Chris Peat...
