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
