Last night I observed Cosmos 2219r at around 9:51 EDT moving NE through the
Keystone.  I seemed to vary in magnitude greatly.  It was not flashing
quickly but seem to change brightness more gradually while it passed over
going from as bright as many of the background stars to almost fading from
view back to bright again.  Does this indicate that it is tumbling?  The
sky conditions were perfect at my location.  I also observed a nice pass of
ISS going by Polaris at 11:16 EDT moving NW to NE.
