Alert Notice 513: Request for observations of GW Lib in support of HST observations
Active Dates: March 18, 2015 – May 2, 2015
Abstract:
Dr. Paula Szkody, University of Washington, has requested our help in monitoring the cataclysmic variable GW Lib for upcoming Hubble Space Telescope observations, scheduled to be made during the window 2015 April 22-25 UT.
Justification:
AAVSO observations are needed to ensure that the object is NOT in outburst when observed with HST. AAVSO observations made April 21-24 will be used to make a go/no go decision, and will also be used in the analysis of the resulting data.
