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 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.
