Dear ASCA users,

I am sending a revised ASCA observation schedule for the period of
September 17-27. We reduce the Galactic ridge survey (JPN, PI: K. Koyama
Priority-C) for exposure time from 50 ksec to 36 ksec and for pointing number
from 10 to 3. In the room, we install a TOO observation to search for the 
4.45-sec Galactic center pulsar, GRO J1750-27.
T. Prince and B. Vaughan  reported that they resolved the pulsar from the
nearby transient GRO J1735-27 (RX J1735.9-2726) and confined the position
to 1d x 0.5d error region (90% confidence). We plan to cover the region by
three pointings, each 5 ksec.
