    Hi all,
    Last night just after the closing of my observing session I noticed a possible short flash near Polaris. I decided nevertheless to wait still for a few seconds for the case I would see another brief flash. It was one at about mag 4 and ... others as well, the brightest ones reaching mag 2. The flashing object turned out to be Iridium 17 in a near zenithal pass (NS h=83°E) and I followed it for at least 3 minutes (23h 52.3 to 23h 55.4 UTC).
    I didn't measure the period, although it was probably in the range 12-20 seconds.
    The same night I noticed several flaring objects, that I was not expecting, the nicest one being a long flare at mag -3 by Cosmos 2441 (#33272 2008-037 A) near Arcturus in a bright twilight (Sun height : -9°2) at 20h49 UTC.
    Identifications were made using Calsky.
