[vsnet-alert 15622] Next HST observations: HS1055+0939 = IU Leo & QZ Lib

[Boris Gaensicke]

Dear All,

STScI will decide tomorrow (17th) on the HST observations
of HS1055+0939 (=IU Leo), please try to get another few
V-band snapshots between now up to the end of the
scheduled HST spectroscopy,

HS1055+0939 	Apr 18, 2013 09:30:11 	Apr 18, 2013 12:05:05

Plus, the next target is now locked into the HST schedule,

QZ-Lib 	                Apr 26, 2013 14:37:44 	Apr 26, 2013 21:23:30

QZ Lib, previously known as ASAS 153616-0839.1, is a relatively
poorly studied WZ Sge dwarf nova that had an outburst in Feb
2004, and as far as I am aware, no additional outburst has ever
been recorded ... but please correct me if I'm wrong on this. Please
monitor QZ Lib closely, it is quite faint (V~19), so long exposures
and stacking may be necessary.

Thanks for your help with those two stars!

Best wishes,

Boris
