    The newly-launched Cosmos 2416 rocket has been observed flashing
    by Leo and Bram.  Ed and I observed it last night.  Unlike the
    period of 2.6 seconds obtained by Leo and Bram a few days ago
    with indications of secondary flashes, I oberved a very regular
    flashing with a period of 2.0 seconds:

    The Spacecom tles show a changing mean motion for the first
    several days after launch.  So I assume that residual fuel/oxidizer
    gases were being vented.  The tles show a nearly-constant mean motion
    for the last day, so perhaps this has ended.
