    The flash period of LES 8 continues to decrease by about one 
    second from night to night!  It also flashes something like 
    12-14 (?) minutes earlier each night even though it's not 
    drifting.  Here are PPAS reports:
    
    08746, LES 8 (The last two are new; the first two are repeated 
    here for comparison.)
    76-023 A 05-09-07 05:24      SDL       0.5  36 128.9  dT=4639.6
    76- 23 A 05-09-13 03:32:19   EC  989.4 0.2   8 123.68 +1.5->i

    76- 23 A 05-09-15 03:08:20   EC  975.5 0.2   8 121.94 +1.5->i
    
    In my three, I used eight cycles when it was flashing at about 
    the brightest magnitude.  
    
    For a bit of puzzlement, last February-March it was observed 
    with a flash period between 35 and 40 seconds, e.g., by Brad 
    Young:
