Subject: outburst of GK Per
According to data received by the AAVSO (AAVSO News Flash No. 924 and
IAU Circular 7841) the old nova GK Per appears have begun one of its
infrequent quasiperiodic outbursts. The following satellite observations
have been approved and are being scheduled: 1) RXTE, 2 ks every 3.5-5.5
days for the length of the outburst [the first observation has already
occured]. 2) XMM; a 35 ks exposure sometime between now and the close of
the target visibility window (sometime between March 7-11). 3) Chandra
HETG; two 35 ks observations, the first the week of March 25, the second
2-3 weeks later. GK Per is currently not well placed for ground-based
observations, so it is important that optical observers strive to monitor
the star throughout the outburst. Observations at other wavelengths are
encouraged.
