ROSAT MISSION
UK Professional Astronomers have asked us to cover various stars
over the coming months and to advise them of an outburst or unusual
activity. This is to assist with the monitoring of stars on the rise
using ROSAT, IUE and optical observatories simultaneously.
If you wish to participate please start immediately but also e-mail
the Editor to confirm.
The high priority list requiring checks EVERY night until further
notice follows:
