Monitoring requested for HST/COS observations of SBS 1108+574
Active Dates: April 29, 2014 – May 25, 2014
Abstract:
Dr. Peter Garnavich (University of Notre Dame) and Dr. Paula Szkody (University of Washington) have requested the help of AAVSO observers in monitoring the cataclysmic variable SBS 1108+574 (= CSS 120422:111127+571239) in support of upcoming Hubble Space Telescope observations. The HST COS (Cosmic Origins Spectrograph) will be carrying out far-ultraviolet spectroscopy of this target on 2014 May 12-13 UT.
Justification:
The primary purpose of the AAVSO monitoring is to know whether SBS 1108+574 is in quiescence immediately prior to the observation window; if it is in outburst it will be too bright for the HST instrumentation. Based on your observations, the HST scheduling team will make the decision about 24 hours before the scheduled observing time as to whether to go forward with the HST observations.
