===================================================================
EG Cnc [UGWZ, 11.9v - 17:v]
===========================
The second major rebrightening of EG Cnc, announced yesterday in
CVC 119, has been followed photometrically by Tonny Vanmunster
at the CBA Observatory, Belgium using a 0.25-m f/6.3 SC telescope
and ST-7 CCD. A period analysis of unfiltered observations during
a 3.5h run (Dec 28/29), using the PDM method, yields a superhump
period of 0.0584 +/- 0.0009 d, after heliocentric correction and
removal of a linear trend of decline. The mean semi-amplitude of
the superhumps is 0.07 mag.
Further time-series photometry in this stage of the outburst is of
utmost importance.
Correction to CVC 119
---------------------
The time, reported in CVC 119, for Vanmunsters CCD observation is
wrong. The correct value is Dec 28.964 UT instead of Dec 28.974 UT.
DX And [UG, 10.9p - 16.4p]
==========================
DX And has returned to quiescence, as one can derive from the photo-
metric summary below.
