RX J0944.5+0357 outburst observations update

Dear Colleagues,

   We have received further observations from Kiyota-san, Donn Starkey,
and Maehara-san (communicated via the VSOLJ).  The Kyoto team has been
also regularly following this object.

   In the early data (around Dec. 25), there were relatively strong QPO-like
variations.  This variation became less violent in later observations
(likely orbital modulations with harmonics; detailed analysis in progress).
In combination with the earlier claim as a possible intermediate polar
(Mennickent et al. 2002, A&A 383, 933), the early QPO-like variation
may reflect transient IP pulses, as seen in anothor suggested IP-like
dwarf nova, CW Mon (Kato et al. 2003, PASJ 55, 489).  The outburst
light curve up to now also resembles that of CW Mon.

   Further observations and analysis are in progress.  Please keep this
rare(?) bright outburst on your target list before UZ Boo rises (in the
north).

Regards,
Taichi Kato
