OR And new HST target
The VY Scl star OR And has entered its low state and Dr. Boris Gaensicke and colleagues are scheduling HST/COS to observe this target of opportunity within the major CV campaign underway. It is very faint now at V=18th magnitude. Observations are needed now and for the next few weeks. Please see AAVSO Special Notice #359 for details and instructions on how to observe OR And for this campaign.
Thank you and good observing - Elizabeth Waagen
