[vsnet-alert 27998] Call for monitoring of SS Cyg

Dear colleagues,

We would like to call for dense monitoring of SS Cyg for coming tens of days. X-ray observations by the new X-ray telescope XRISM (PI: Manabu Ishida) will be scheduled based on optical detection of the next outburst. The SS Cyg observation window with XRISM will open on April 14. We would be thankful, if the VSNET observers would monitor SS Cyg more than usual and timely report outburst detection, say brighter than V=11.0.
