    One important question that amateurs can help answer is the size of the
    rocket body associated with the Iranian satellite.  Was there a third stage
    hidden inside the clamshell nose faring?  Or did Iran manage to put this
    satellite into orbit using the two visible stages of the Safir rocket?  My
    estimate is that the Safir's second stage is about 5 m long by 1.25 m in
    diameter while a hypothetical third stage would be considerably smaller (on
    the other of 1 m long?)  Id be interested in any such brightness
    measurements that might be able to answer this.
    Best regards, Geoff
