Alert Notice 586: Status of 20 cataclysmic variables needed for WHT campaign

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.

2003+17  WZ SAGITTAE IN OUTBURST

Special Notice #362: OR And and AX For obs critical now

July 8, 2013: The VY Scl variable OR And continues in its low state, so it has been scheduled for HST/COS observations. Based on your observations, the HST/COS team will be making the final decision tomorrow morning (2013 July 9) whether to observe OR And on:

OR And 2013 July 10 11:47:01 through 15:56:12 UT

OR And is ~18V in its low state and ~14.5V in its high state.

HST/COS is scheduled to observe the SU UMa variable AX For on the next day:
