    hello all,
    
    This evening I first observed Gorizont 23 = 21533 = 91- 46 A.  This time it
    was rather faint.
    Compared with the mag +6 of last week, it now was just visible around mag +9
    through the
    telescope with a nearby moon.
    The period seems to be going up slowly again, so the acceleration observed
    by Stephen during
    November 2000 must have been finished already.
    
    In between I also tried Gorizont 17, as it was reported bright by Rob at the
    end of January.
    I only put my binocular to the appropriate field and yes there it was,
    flashing to a magnitude
    of 4 to 5, so an easy binocular object !  This period of this one is still
    going down, today it
    was 79.48 seconds.
