    Last night Raduga 33 (96-010A, 23794) put on a great show.
    It did a series of 8 or 9 flashes up to at least zero
    magnitude at the brightest.  They were every 33.2 seconds, 
    from 4:35:09.0 to 4:40:07.7.  In Mike's 200mm scope, 
    secondary and tertiary maxima were visible.  The range 
    was more than 4800 km and increasing.  These were roughly 
    from RA 22:41, Dec. +61.0, to RA 23:48, Dec. +54.3 (2000).
    
    We saw Envisat and its Ariane.  By that time, from here,
    Envisat was brighter.  Two other "conjunctions" that I 
    saw with my 10x50s were MER-A Delta Rk (03-027C, 27829) 
    and Okean O (99-039A, 25860), and CBERS 1 Rk Debris DL
    (99-057DL, 26222, which tumbles) and Cosmos 968 Rk 
    (77-119B, 10521).
    
    I saw the following without magnification in the moonlight
    and with scattered cirrus conditions:
    
    06155 72-065B OAO 3 Rk (Centaur?)
    06779 71-116B Intelsat 4-F3 Rk (Centaur; quite bright)
    11683 80-008B Cosmos 1154 Rk
    12586 81-065B Meteor 1-31 Rk (not easy this time)
    17191 86-097A Cosmos 1805
    22566 93-016B Cosmos 2237 Rk (Zenit)
    22997 94-010C Shi Jian 4 Rk (Long March, quite bright)
    23323 94-068A IRS-P2 (only one 1x flash this pass)
    23794 96-010A Raduga 33 (wow!)
    23851 96-024A MSX (not easy this time)
    24297 96-051A Cosmos 2333
    25544 98-067A ISS
    25860 99-039A Okean O
    25861 99-039B Okean O Rk (Zenit -- brightest non-payload?)
    26405 00-039B CHAMP (flare)
    
    Observing location was 30.315N, 97.866W, 280m.
    
    USA 102 (94-017B, 23031) continues to elude.
