    All previous observed passes were southwest to northeast.  Those showed a steady magnitude other than phase again/distance changes although there was a steeper than expected drop after culmination.
    This one was basically west to east in the north.  Max elevation 19 degrees.
    Picked it up in binoculars about 00:28:30 (HH:MM:SS) UTC in the Ursa Major (Big Dipper) handle.  It seemed to get a bit brighter than initial obs and soon noticeably decreased in brightness.  It got brighter and I guess the period at 30 seconds.  This is very rough since the brightness change is relatively flat.
    Brightness did decrease again but it entered the shadow before I could see if it brightened once more.
