Hi all,

What's going on with ETS-7?  I observed an UnId on a similar trajectory
and time.  Observed Traj of UnId was a couple of degrees above the
predicted Traj of ETS-7 and 97074E.  (it was supposed to pass below
Psa but passed above it instead and was flashing/rotating with a 5.58s
period).  Nothing else in the latest alldat.tle was even close.

Observed Iridium 79 tum.  No flashes but rotation was apparent with
a photometric period of 4.212s

98- 51D 98-12-2 23:27:26.95 JN 33.7 .2 08 4.2125 4.5->inv   imM

Although earlier in the pass I counted a period of 8.4 secs and a flash
the Maxima  or  imMmf -or- imMif.

Lacrosse 2 and NOSS 2-3 rk also observed and positions noted.
