Dear CBAers,

As some of you know, GK Per just jumped into outburst.  Not the greatest
placement in the evening sky - we put Perseus to bed a long time ago - but
the scientific interest here is in the properties of the 351 s signal well
known from the X-ray (and with some effort seen in the optical as well).
Even though Perseus will only be up a couple hours, that's long enough to
get about 20 cycles of the oscillation... and hence to get a measurement
or useful upper limit.

The present campaigns on BP Lyn, TT Boo, and EC0511 are going very well...
but see if you can pop off some observations of GK Per in the early
evening.  Full CBA letter coming Friday.
