I'm sorry that I have been unable to post my usual Decay Watch notes for
a couple of days. As you know from other messages on SeeSat, the re-
entry of the GE-6 Proton rocket was undoubtedly observed earlier today
from Australia. I have (at last) updated my Decay Watch page of which
the following is abstracted...

and leaves eclipse while northbound near 11 deg S before dawn.

Note: This re-entry was observed from Australia as it followed a path
from the vicinity of Esperance at ~11:42 UTC to pass E of the Giles
Meteorological station ( 25S, 128E). This is a little beyond my
SatEvo-predicted point, but consistent with my analysis which
suggested that there was a chance that this might even survive until
the following northbound equator crossing near 150.6 E at 11:52
