Dr. Stella Kafka (AAVSO) has requested multicolor photometry and spectra of the dwarf nova SS Cyg to complement monitoring by the TESS satellite taking place now to mid-September.
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.

SPECIAL AAVSO ALERT NOTICE ON DWARF NOVAE
Do continue your close monitoring of dwarf novae. Dr. Stiening from Stanford University and his colleagues will be observing these stars from Nov. 25th to Dec. 4th at Mt. Lemon, Arizona, and they have requested our help once again.
