    Hi all,
    Observed ATV-4 pass twice from Leiden (the Netherlands) this night, at 23:47 UT 
    and 1:20 UT. Captured it visually, photographically and on video. The 23:47 UT 
    pass was a zenith pass for me.
    During both passes it was bright (mag +1 during the 23:47 pass, mag +0.5 during 
    the 01:20 morning twilight pass) and a very easy naked eye object.
    During the 23:47 pass a second, much fainter object preceded the ATV by a few 
    seconds: most likely this was the Ariane upper stage from the launch. I captured 
    both objects on photo and video.
    Photo's and video will follow later - I need some sleep now.
