EG Cnc [UGWZ, 11.9v - 17:v]
===========================
We have been informed by Jonathan Kemp, CBA New-York, observing
from Cerro Tololo, Chile and Taichi Kato, Ouda Observatory, Japan
that EG Cnc is again experiencing a major rebrightening !
Kemp observed the object during a 2h time series photometry session
(Jan 3/4) and saw it brightening by about 0.25 mag (to approx. mag.
13.55). A rough estimate of the magnitude on Jan 4.47 UT (judged
by Kato from a TV monitor) is V ~ 13.72.
Please continue to follow this most spectacular object ! The table
below is a continuation of the one published in CVC 120.
