Dear colleagues,
We would highly acknowledge your close monitoring of SS Cyg recent nights! Unfortunately, the rising phase of the current outburst that we had aimed at has already been over before an XRISM observation can start. However, we will try it again at the next chance, hopefully in the coming mid-to-late May. We would be very grateful if the VSNET observers continued the monitoring and could catch the onset of the next outburst!
With best regards, Daisaku Nogami --- Daisaku NOGAMI nogami@kusastro.kyoto-u.ac.jp

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.
Best regards, Daisaku Nogami
