    Waves to Kent! Where do you live??? I'm in Morgan Hill..
    (Which reminds me.. Anyone who is interested we are heading to Lathrop, CA
    for a nice lunar graze around 5am Sunday.. Email me if interested..
    Remember. I do satellites so you'll do occultations! :-)   )
    ***Rosat's last best pass here.***
    Ummm No.. 
    About the same time every night until decay..
    All the passes are generally better than this one... 
    As for ROSAT.. Yep.. -6 to -8 is right.. Video is posting..

    I must have seen the same flare Derek captured on the 0226Z Rosat pass over 
    Northern California. Rosat was 3.2 seconds early re: the 11292.83406727 
    elset. Magnitude around 0 with a short-duration flare to perhaps -6 to -8, 
    comparable to brightest Iridiums. Flare peak was very short duration -- 
    under a second -- more of a flash.
    Faedout into shadow seemed to encompass a longer distance of the arc that is
    typical. Perhaps being closer to the atmosphere, the twilight effect is 
    more pronounced.
    Nice show -- Rosat's last best pass here.
