ASCA weekly

[Fumiaki NAGASE <nagase@astro.isas.ac.jp>]

Dear ASCA users;

We accepted the TOO request by Y. Tanaka, J. Greisner and J. van Paradijs 
to observe the X-ray afterglaw of the GRB970616. This gamma-ray burst was
detected by BASTE and the X-ray afterglaw was detected and the position
was confined to 0.5 degree with the RXTE PCA scanning.

This is the first TOO to which the new ASCA TOO rule is adopted and the data
belong to the PI (Y. Tanaka). I wish to assign T. Murakami, A. Yoshida and 
N. Kawai to be CoIs  from the ASCA operation team, assuming they will 
cooperate to the PI by careing the observation and analysing the data quickly.
The target, TW Hya (MUJ, PPI: J. Kastner) is kicked out by this TOO, but 
I will try to restall this target in the currently visible window since 
this is a priority-A target.

At present a typhoon is aproaching to Kagoshima and it is expected to aproach
closest to KSC during tomorrow (July 20) KSC operations. If the wind is too 
strong to operate the antenna we will stop whole the operation of the day, 
regardless the targets are regularly scheduled ones or  the TOO target.

F. Nagase
