Dear,
I just finished a first CCD observing run on CW Mon (Jan 07/08, 2000), which lasted for about 3.6 h, under good conditions. I have been using the 0.35-m f/6.3 telescope of CBA Belgium Observatory and an unfiltered ST-7 CCD camera. I'm not exactly sure what to think about the resulting light curve. It clearly shows a (complex) combination of periodic modulations (0.051 d, 0.081 d, ...). This likely is stuff for the experts !
For those interested, I have included an extract of my observation results. You can easily plot them using MS Excel or another graphing tool. I'd be interested to hear opinions and interpretations of other readers.
There has been some work done on this object by P. Szkody, S. Howell and Mateo. They have catalogued it as an UG object and derived an orbital period of 4.23 h.
Best regards,
Tonny
