[vsnet-alert 16416] Next HST observations: BB Ari

[Boris Gaensicke]

Dear All,

the HST observations of GZ Cet went well, another textbook
spectrum of an accreting white dwarf in the bag. Thanks a lot
for your help with monitoring this star, which is the key to
get those observations approved!

The next target is BB Ari, and we now have a fixed schedule:

Sep 27, 2013 03:01:26 to 06:29:37

It is a SU UMa type dwarf nova, that had a superoutburst
in the middle of August. The frequency of normal outbursts
is not terribly well known, so we need your help to keep
a close eye on BB Ari until the scheduled HST observations.

After BB Ari, there will be a long break, with the final star
(SDSS1006+2337) provisionally planned for March 2014.

Best wishes,

Boris
