EG Cnc [UGSU, 11.9v - 17:v]
===========================
Unfiltered CCD photometry by Tonny Vanmunster at the CBA Observatory,
Belgium shows that EG Cnc is now having a second major post-outburst
rebrightening. The event has been confirmed visually by Gary Poyner,
Birmingham. Here are the observations :
1996 Dec 28.974 UT, 13.6 (T. Vanmunster, 0.25-m SCT, unfilt. CCD);
Dec 28.969 UT, 13.6 (G. Poyner, 0.40-m refl., seq: VSNET);
We are now (Dec 29.0 UT) performing time-series CCD photometry on this
object, which we hope to continue till about Dec 29.3 UT. It will be
extremely interesting to find out if superhumps are again appearing
and, if so, to determine the associated superhump period in this stage.
Remark that UZ Boo also showed a second post-outburst brightening
during its August 1994 outburst [CVC 16].
Other recent observations of EG Cnc are summarized in the table
below and complement the reports in previous CVC circulars.
