ASCA weekly
Dear ASCA users,
It was reported by Dr. Stuart Bowyer that they discovered in their EUVE
archival data a giant outburst from a galaxy in the Abell cluster 1795.
They informed also that the outburst is declining but yet visible in the
EUVE follow-up observations. They suspect that this is an event similar with
the giant soft X-ray outburst in galaxies several times observed with ROSAT
and S. Bowyer proposed an ASCA TOO observation in coordination with a further
EUVE follow-up observation. We have accepted this request of ASCA/EUVE
coordinated observation of the EUVE giant outburst discovered in a galaxy.
Although contamination from the cluster core is suspected, we will be able
to compare the image observed with the archival data of the cluster take
before the outburst. The observation of G296.8-0.3 once scheduled in the
span of July 14-15 is replaced by the TOO observation of this outburst and
it is carried to the next window. I will assign later the Japanese CoIs for
this TOO.
