    Hi all,
    Two nights ago I filmed the NOSS 3-3 rocket (05-004B), showing its well known 
    brightness variability due to tumbling.
    The video, plus a derived brightness curve, can be seen here:
    The resulting curve is very nice, a sharp-peaked saw-tooth pattern with a period 
    of 11.4 seconds.
    Brightness data were extracted from the movie frames using LiMovie.
