ASCA Weekly from Prof. Nagase (listserv problem, resending)



Dear ASCA users,

Four slots of Galactic zero-longitude observations by Maeda that was
once planned to be start on April 12 was shifted after April 17. Instead, 
we have installed the observation of NGC 3516 in the interval of April 
12 to 17, although the moon constraint of the source during the time 
is somehow severe. Feasibility  of this observation during the bad STT 
condition has been specially studied and confirmed, since this is a big 
coordinated project  planned to be observed simultaneously with HST 
and RXTE. Re-observation of the AO-5 target  SGR 1900+14 is scheduled 
in this week. This source was once planned to be observed in the last fall, 
but the pointing to the source was failed by mistake.

F. Nagase
