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.

August 25, 2012: Dr. Nikolaus Vogt (Universidad de Valparaiso, Chile) has requested photometry and spectroscopy of the novalike (VY Scl subtype) cataclysmic variable TT Ari in support of upcoming observations with the Canadian Microvariability and Oscillations of Stars (MOST) satellite.
Just over one year ago, a small spacecraft called MOST began a month-long observing run on one of the most spectacular objects in Earth's skies, the beautiful Trapezium region at the heart of the Orion Nebula, M42. My collaborators and I applied for and received this observing time to survey variability in this young stellar cluster -- partly to study the eclipsing binary BM Ori (theta 01 Orionis B), but also to survey as many young stars that we were able to using the unique capabilities of MOST. Since then, I along with my collaborators -- our Director Arne H
