Alert Notice 663: 1SWASP J022916.91-395901.4 being observed with Chandra
March 8, 2019: Further to AAVSO Alert Notice 652, Dr. Koji Mukai (NASA-Greenbelt Space Flight Center) informs us that 1SWASP J022916.91-395901.4, one of the novalike variables in his target list, will be observed with Chandra on 2019 March 11 22:35 UT - 2019 March 12 02:45 UT.
Special Notice #75: Monitoring of TT Ari in support of MOST observations
October 22, 2007: The Microvariability and Oscillations of Stars (MOST) Satellite will conduct a targeted photometric observing campaign on the cataclysmic variable TT Ari, beginning 2007 October 23 UT (JD 2454397) and concluding on 2007 October 28 (JD 2454402). This observing program was proposed by a group of Austrian amateur astronomers who proposed to the "MOST fuer Alle" program of the University of Vienna, the Austrian partner project of the MOST collaboration's "My Own Space Telescope" program for Canadian observers.

Alert Notice 386: Low state of VY Scl
October 2, 2008 : The cataclysmic variable VY Scl appears to have recently entered a low state according to observations recently submitted to the AAVSO. Javier Temprano reports positive detections of VY Scl at CV=17.46 on JD 2454730.46181 (2008 Sept 20.9618) and at CV=18.23 on JD 2454730.572 (2008 Sept 21.072).

Alert Notice 389: Support for VLT spectroscopy of the novalike variable VY Scl
November 11, 2008 : Dr. Steve Howell (NOAO, Tucson) informs us that he has been awarded time to obtain spectroscopic observations of the cataclysmic variable VY Scl with the Very Large Telescope in Chile. These observations are being sought during VY Scl's current deep minimum, which began some time before 2008 September 20 (JD 2454730). VLT observations are scheduled via prioritized queue, and the exact observation time is not yet known; however, observations are expected within 1-2 weeks.
