Alert Notice 675: V386 Ser - second rescheduling of HST observations
Abstract:
Further to AAVSO Alert Notices 669 and 667, Dr. Paula Szkody (University of Washington) informs us that the HST observations of the cataclysmic variable V386 Ser originally scheduled for June and rescheduled to early August have been rescheduled again for 2019 August 15 or 16 (the exact date and time are not yet known). AAVSO observations are essential to know the state of the V386 Ser system in order to ensure that the system is NOT in outburst when observed with HST. AAVSO observations made 24 hours before the HST observing time will be used to make a go/no-go decision; AAVSO data will be used in the analysis of the resulting HST data.
Justification:
It is essential to continue obtaining nightly snapshots in order to know the status of this system from now through the HST observation window. Intensive monitoring is requested August 12 through August 17; this period of intensive monitoring may be adjusted when the exact time of the HST observations is known. AAVSO observations are essential to know the state of the V386 Ser system in order to ensure that the system is NOT in outburst when observed with HST.
