Photometry from Cerro Tololo on the 1-meter (1 December, UT)...
EG Cnc: V = 12.20 @ HJD 2450418.8355
Field stars of possible interest to CCD observers for comparison purposes
(positions are my best estimates and are approximate):
2.8' W, 0.3' S : V = 13.86, B-V = 0.66
3.1' W, 0.9' N : V = 15.64, B-V = 0.81
4.0' W, 0.5' N : V = 12.82, B-V = 0.73
EG Cnc is very unfavorably placed for my southern latitude and short
nights. I did manage a very short time series on it. All of the above
observations were made at sec z > 1.9. I still need to verify my
calibration calculations from the standards I observed, but I figure this
will give you something to go on.
Additionally, some provisional data on comparison stars marked on CBA
PX And comp 1: V = 13.63, B-V = 0.71
PX And comp 2: V = 14.34, B-V = 0.61
RR Pic comp 1: V = 13.06, B-V = 0.85
RR Pic comp 2: V = 10.92, B-V = 1.08
And, foreseeing a possible spring campaign, V 803 Cen (= AE 1, a helium
CV) comparison star roughly 2.2' S, 0.2' E is V = 13.39, B-V = 0.59.
