Superbird B1 flashes

Hi all,

This evening I captured bright flashes from what turns out to be
Superbird B1 [21893/92010A]. The flashes appear to have a period of
about 28 seconds, and around 20:03UT I estimate them at magnitude 3.
The flashes decreased in brightness until they were no longer visible
around 21:00UT (estimated to be fainter than mag 8-9). It may be that
the flashes were even brighter before 20:03UT.

These flashes may be reminiscent of those of Superbird A
[20040/89041A]. For that satellite, the spin axis could be determine,
which allowed Rob Matson to predict when flashes would be brightest
for a given location on Earth. For a blast from the past, have a look
at http://www.satobs.org/seesat/Oct-1996/0079.html and the SeeSat-L
archives on Superbird A flashes.

It may be worthwhile to monitor the flash behaviour of Superbird B1.
Superbird B1 is slightly above the geostationary belt and is moving
West. It currently is around 37 deg West.

Regards,
    Cees
