Greetings all,

Based on observations made by Tony Beresford in southern Australia, I've
determined a preliminary rotation axis for ETS-6 (#23230).  Axis is
RA 19.3571, Dec +73.623, half-cone angle of 86.11 degrees.  So, like
Superbird A, it appears to be spinning end-over-end.  I've only had a
few
minutes to check for when/where it will be flashing.  Early tomorrow
morning (Friday, July 24), it will be flashing when it comes out of
shadow
around 11:02 UTC (5:02am MDT) as seen from the southeastern third of
Arizona, and the southern half of New Mexico.  San Diego may see dim
flashes at this time, but the city is north of the centerline.  Flashes
could
last up to half an hour -- the further south you are, the longer you'll
see
flashes.  ETS-6 will be low in the southwest sky.  For example, it will
be about 14 degrees above the horizon for Albuquerque, 17 degrees for
Flagstaff, and 22 degrees for San Diego.  --Rob
