ASCA weekly



Dear ASCA users,

An ASCA TOO observation of the new X-ray transient, XTE J1859+226,
requested by M. McCollough was accepted. We allocate  a 20-ksec observation
of the source on October 23, by reducing the exposure time of the priority-C
target, CTB 80 Shell, from 60 ksec to 40 ksec. I have tentatively assigned
Drs. N. Kawai and Y. Ueda as Japanese CoIs.
