HST observations scheduled for SDSS J153817.35+512338.0

Active Dates: March 29, 2018 – April 30, 2018


Abstract:

Further to AAVSO Alert Notice 618, Anna Pala (Ph.D. candidate, University of Warwick) informs us that the date and time of the HST observations planned for the faint polar cataclysmic variable SDSS J153817.35+512338.0 have been set for 2018 April 6 17:33:26 - 21:33:19 UT. It is essential to know the brightness of the target just prior to the HST observations in order to protect the satellite equipment. A go/nogo decision will be made 24 hours prior to the observation time based on positive magnitude reports from AAVSO observers.

Justification:

It is essential to know the brightness of the target just prior to the HST observations in order to protect the satellite equipment.
