    Hi All
    
    Last night I observed Lacrosse 2 which flared nicely at 20:37:33UTC. I only
    have a record of one other flare by Lacrosse 2 on 10/06/06 as observed by
    Marco. Marco's observation suggested a panel angle of 30 degrees in flight
    mode XVV. This new observation fits a 30 degree panel angle but in flight
    mode YVV (i.e. the spacecraft has rotated precisely 90 degrees between
    observations). If the flare is from a dish antenna then I'm not sure what it
    means!
    
    Meanwhile Lacrosse 3 faded suddenly by 0.5 magnitudes in the middle of the
    pass. Maybe not as dramatic as Lacrosse 5 but it proves the other satellites
    can do it. The Lacrosse 3 light curve is here
