V729 Sgr: eclipse observed by Greg Bolt! Dear Colleagues, We have time-series observation of V729 Sgr (May 10) from Greg Bolt. The data clearly caught an eclipse during outburst! The eclipse was rather shallow (as expected) with a depth of 0.1-0.2 mag and a duration of 30 min. From the eclipse shape and depth, the outer part of the accretion disk was likely eclipsed. The event occurred close to the predicted time: no immediate need to update the ephemeris. The eclipse light curve was rather asymmetric, probably caused by a pre-eclipse hump-like variation. The light curve outside the eclipses was rather variable up to 0.1 mag. When observing time allows, observe on possible occasions this star for some eclipses, since the object is proposed to be a candidate rare eclipsing Z Cam-type star (although no definite standstills have been identified).
