CW Mon: (probable) eclipse detection by Kiyota-san Dear Colleagues, Kiyota-san (Tsukuba, Japan) obtained time-series CCD photometry of CW Mon during the current (relatively rare) outburst. An eclipse-like fading (depth 0.2 mag in V, duration ~40 min) was clearly recorded in Nov. 3 long observation. Although the feature became less sharp, a similar fading was observed on Nov. 4. These observations, together with the suggested large inclination (Szkody and Mateo 1986, AJ, 92, 483), suggest that these fadings correspond to grazing eclipses as seen in U Gem. Since the orbital period has not been yet exactly established to make an ephemeris (the period by Szkody and Mateo was derived from a single-night IR observation), long (prefrerably 4 hours until dawn) nightly observations are strongly encourged to unambiguously identify the (probable) eclipses. We are very looking forward to receiving further observations. Regards, Taichi Kato VSNET Collaboration team
