Note: RY Ser was scheduled for May and for June but was in outburst or too close to outburst to be a safe target. It may be rescheduled. GP Com observations did take place. - Elizabeth O. Waagen, July 5, 2022
GP Com observations will take place April 29-30, 2022; coverage is needed until May 20. See Alert Notice 775. - Elizabeth O. Waagen, April 27, 2022
July 7, 2017: Roque Ruiz-Carmona (Ph.D. candidate, Institute of Mathematics, Astrophysics and Particle Physics, Radboud University Nijmegen, The Netherlands) has requested AAVSO assistance in determining the status of 20 eclipsing cataclysmic variables (CVs) in order to select one system in outburst for observation with the William Herschel Telescope (WHT) at La Palma, to detect and study spiral density waves in the system. The WHT observations will begin on 2017 July 11 UT.
May 25, 2016: Roque Ruiz-Carmona, the principal investigator on the observing campaign on 20 CVs that was announced in AAVSO Alert Notice 543, reports that the campaign has been revised due to telescope issues. He writes:
