February 15, 2017: Dr. Elmé Breedt (University of Warwick) has requested AAVSO observers' assistance in monitoring the eclipsing cataclysmic variable 1SWASP J162117.36+441254.2 (=CSS_J162117.4+441254) beginning now in support of observations scheduled with the Hubble Space Telescope for late February - early March.
February 10, 2017: Dr. Ed Sion (Villanova University) and colleagues have requested AAVSO observers' assistance in monitoring the symbiotic-type recurrent nova IM Nor in support of observations with the Hubble Space Telescope Cosmic Origins Spectrograph scheduled for 2017 February 13 - 17 UT.
These observations are part of a study on short orbital period recurrent novae as Supernovae Type Ia progenitors.
October 19, 2016: Dr. Edward Sion (Villanova University) has requested AAVSO observers' assistance in monitoring the recurrent nova CI Aql in support of observations with the Hubble Space Telescope Cosmic Origins Spectrograph scheduled for October 31 - November 2, 2016, and November 3 - November 5, 2016. These observations are part of a study on short orbital period recurrent novae as Supernovae Type Ia progenitors.
