[vsnet-alert 15672] Re: Next HST observations: 1RXSJ105010.3-140431 (and a sneak-peak of SDSS1538+5123)

[Boris Gaensicke]

Dear All,

just a quick update on my last message: SDSSJ1538+5123 is now
firmly scheduled for HST observations, i.e. the next two
HST observations will be:

* 1RXSJ105010.3-140431 May 10, 2013 07:51:01 to 12:01:57

and

* SDSSJ1538+5123    May 16, 2013 22:44:06 to May 17, 2013 02:14:05

Please keep monitoring both until the time of the HST observations.

We also got the longer term plan for the next ~2 months. The
dates observations are not yet totally fixed, but STScI will try
to stick to the week starting with the given date. Of these
stars, DT Oct, BD Pav, and QZ Ser are the most active, and
it would be useful to start looking at them more regularly from now
on (~once or twice a night), so that we are aware of any ongoing
outburst in the weeks leading up to the HST observations.

DT Oct  May 20
GW Lib  May 27
V1108 Her Jun 3
BD Pav Jun 10
QZ Ser Jun 17

I will provide some more background information on those five
when we are getting a bit closer to their HST observations.

Best wishes,

Boris
