Dear colleagues, Tonight (September 16/17, 2003) is clear again at CBA Belgium Observatory, with much better sky conditions than yesterday. Using the 0.35-m f/6.3 telescope and ST-7 CCD, I performed unfiltered photometry on V585 Lyr for 3 hours AND 46 MINUTES. Similar to the nights before, the light curve (see www.cbabelgium.com) is not showing modulations with an amplitude > 0.1 mag. I used the PDM technique to look for periodicities in tonight's light curve, as well as in the combined light curves, but no significant signal could be detected. Over the course of tonight's session, V585 Lyr faded by approx. 0.15 mag. Although there is still a chance that the variable is an SU UMa-type dwarf nova, currently undergoing a normal outburst, the chances are higher that this is a long-period system. Kind regards, Tonny Vanmunster CBA Belgium Observatory www.cbabelgium.com
