    Observed 33440 2008-058-B Cosmos 2445 R yesterday morning on a dawn shadow 
    exit pass in a clear moonlit sky.
    This started off as a quick 1X look at this pass (in view of the early hour) 
    which was due to commence at 4:33:33 on November 19 local (1533:33 on the 
    18th UTC)  and be around mag 2.4 at culmination  decreasing to 9.5 mag on 
    However immediately on acquisition I noticed it appeared to be flaring to 
    around 1 mag in what appeared to be an irregular pattern, and looking 
    through binoculars this seemed to confirm that that was the case.   Sorry 
    for lack of precision, I did attempt a count but was not able to do this 
    accurately in the circumstances.
    I have upgraded to Olympus 10 x 50 DPS i binoculars  and these are proving 
    their worth. and  are not too heavy for the relatively short duration of 
    satellite passes.
    I was hoping to confirm this flashing this morning on its 1508 UTC shadow 
    exit pass, but not observed for some reason:  though there was some cloud 
    there was reasonable visibility in the area of interest. (Another spinoff of 
    the upgrade to 10 x 50, much more is  visible in harder conditions.)  Some 
    consolation for the otherwise abortive early morning start was provided by a 
    meteor sighting.
    Expected visible passes between here and expected decay are not 
    particularly good and cloud is  may build up so it would be good if anyone 
    other observers could check this object.  Though we have daylight passes it 
    doesn't look likely this will be one to decay anywhere near here.
