Note: The HST observations of V386 Ser will take place Friday, 2020 February 28. Positive observations are CRITICAL for the nights of Feb 26-27 and 27-28. Please report observations immediately. - Elizabeth O. Waagen, 2020 February 26

Note: Dr. Szkody informs us that the HST observations of V386 Ser have been scheduled for 2019 Aug 15 22:04:49 UT - Aug 16 00:31:52 UT. The critical night is August 14 - please report your observations of V386 Ser as soon as possible after you make them so that HST can be notified in time to make the go-nogo decision. - Elizabeth O. Waagen, August 6, 2019

August 2, 2019: These HST observations of V386 Ser have been rescheduled to August 15-16. Please see AAVSO Alert Notice 675 for further information and updates. - E. O. Waagen, AAVSO
Updated May 24, 2019: Dr. Paula Szkody informs us that the exact time for the HST observation of V386 Ser has been scheduled for 2019 May 30 04:36-10:15 UT. This is the night of May 29/30 for US observers. Thus, the critical night will be May 28/29 (Wednesday night) to get a measurement to HST so they can proceed to the observation. It will be essential to have positive observations from this night to satisfy the HST planners, so observers with suitable equipment are urged to obtain positive measurements of this faint star.
May 14, 2019: Dr. Mark Kennedy (Jodrell Bank Centre for Astrophysics, University of Manchester) is urgently requesting observations of the potential cataclysmic variable CRTS J105122.8+672528 beginning immediately. This object appears to be in outburst, having brightened to V~16.2 from its minimum magnitude of V~18.5-CV~19.
