Notes: HST will not be able to observe VY Scl at this time, so the observations have been canceled. However, the data being obtained by you continue to be extremely valuable to the astronomers, and continuing coverage is requested until after VY Scl has returned to its bright state. Thank you! - Elizabeth O. Waagen, January 31, 2024
Note: Please continue to monitor these targets per the instructions below. - Elizabeth O. Waagen, October 31, 2022, August 6, 2024

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.
