    Hello everyone,
    		I just had a nice observation of the bright geoflasher Gorizont 14
    (87040A) , which was flashing as brightly as magnitude +3. Counting 32
    periods I got a period of 42.63s (last flash counted at 20:44 UT, 10th
    Jan 2000). On the 30th September I timed this satellites flash period at
    43.85s, so the flash period appears to be accelerating. 
    
    A look through the PPAS database suggests that Gorizont 14 may show
    cycles of accelerations & decelerations like that of Gorizont 23, so
    this object is worth observing to see if this can be confirmed. 
    
    Gorizont 14 takes approx. 37 days to completely circle the earth. So
    will be visible over most of Europe for the next week, before becoming
    visible over the United States. Also a reminder that Raduga 27, another
    bright geoflasher is also well placed for observations from Europe. The
    flash period of this satelite is going up, with a period of just over
    94s on the 1st January. Flashes are typically mag +6.
