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 --- Daisaku NOGAMI nogami@kusastro.kyoto-u.ac.jp
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!

Dear colleagues,
We are exditedly waiting for the coming outburst in SS Cyg to catch the rising phase of it by XRISM! SS Cyg seems to have been showing some activity recently. Please continue to keep a close eye on this star! Thanks in advance.

Dear colleagues,
A new outburst of SS Cyg was caught in the very early phase, thanks to your cooperations! Then, ToO observations of XRISM was triggered, though it is now clear when an actual observation start. We would ask observers to continue a close monitoring, or time-series photometry if possible, of SS Cyg for coming days.
Please use vsnet-campaign-report@ooruri.kusastro.kyoto-u.ac.jp to report your time-series data, as usual.

Dear colleagues,
Observations by the X-ray telescope XRISM were smoothly scheduled, and the first observation will start at 11:18 (UT) on June 4, namely ~6 hours later! These observations will continue a couple of days and cover the peak of the current outburst. We would ask you to make simultaneous photometric observations with XRISM!

Dear colleagues,
We would like to express our sincere thanks to all SS Cyg observers. The observations with the X-ray space telescope XRISM have been completed. The outburst of SS Cyg is still continuing, but we would end this SS Cyg observation campaign.
