    I managed a few brightness observations of Omid's rocket body (09004B / 33507),
    which may have regularly varied in brightness. Taking into consideration my
    observations, and those reported to-date by Russell Eberst, Gerhard Holtkamp,
    John Locker and Alan Pickup, I estimate standard magnitude of roughly 6.2 (1000
    km range, 90 deg phase angle). Given the small number of observations, the
    uncertainty in standard magnitude is at least 1 magnitude. 
    
    Agena rockets are about 6 m x 1.5 m, and have standard magnitude of about 5.6,
    so Omid's rocket may be a bit smaller, but additional observations are required
    to draw conclusions.
    
    I also attempted to spot Omid (09004A / 33506), despite unfavourable range and
    phase angle, but did not see it. I had hoped to measure its period of brightness
    variation.
