    Hi all,
    Weather finally allowed me to observe one of the new Iranian objects from the 
    February 2nd launch. It concerned the rocket booster from the launch, the Safir 
    2 r/b (09-004B).
    Conditions were not perfect (somewhat hazy), but the rocket booster was well 
    visible and I captured it on two wide field images, which together with the 
    derived brightness profiles can be seen here:
    09-004B showed a clear very slow amplitude brightness variation (amplitude >20 
    seconds), going between mag. +3 and near-invisibility for the naked eye (> +4). 
    Around the brightness peak it gives a short bright glint. Both my photographs 
    captured such a glint.
    If weather allows, hope to capture OMID as well (stayed below the rooftops this
