    Hi all,
    
    I observed a splendid mag -7.5 or so flare by Iridium 03 (98-048A) this evening 
    at 18:22:50.8 UTC. A photograph can be seen here:

    As it turned out, chance had it that the people from Grimbergen observatory in 
    Belgium (Philippe Mollet et al.) located 135.9 km south of my location, observed 
    the same flare from the same Iridium. While I had the center of the flarepath at 
    4.8 km West of me at 18:22:50.8 UTC, they had the center of the flare path at 
    4.6 km East of them at 18:22:28.9 UTC. So the geometries were virtually the same 
    (with a predicted brightness of mag. -7.7 for Grimbergen, versus -7.5 for me), 
    they having the flare maximum 20.9s earlier in time than me. What a nice 
    coincidence!
