HST exact time scheduled for V386 Ser

Hi Observers,

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.

Please switch from nightly monitoring to intensive monitoring (several times per night) on May 26/27 and continue through June 1/2, then resume nightly monitoring through June 7/8.

AAVSO Alert Notice 667 has been updated with this information.

Many thanks, and Good observing,

Elizabeth

HST observation of V386 Ser

Thanks to all the wonderful observers who posted observations before and during our scheduled HST observations. Unfortunately, the aging telescope had jitter when it went to our source and could not find the guide stars to hold the pointing and so the observation had zero data. There was no way to foresee this and they have approved a repeat observation. We don't know yet when that will be but hopefully before September when we can't see it from the ground anymore. The optical data taken will be useful to search for optical periodicities and so is still a valuable addition. I hope that some of you will  be willing to continue observing this object for when we make the second attempt and thanks again for all your efforts, very much appreciated!

Too bad, sorry to hear that!

Too bad, sorry to hear that!

Well, better luck next time, and this was fun anyway as this was testing the limits of what I can do with my equipment & site.
