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.
