Dear ASCA users: As you may remind, Nova Sco (GRO J1655-40) is now undergoing an outbursts (IAUC #6196, #6201, #6203). Since this source comes into ASCA visible window after August 12, we have allocated a TOO observation of Nova Sco on August 15. According to this allocation the observation of PG1553+11 is shifted about one day and the previously allocated observation of "Galactic Longitude at l = 325.1 degree" (Japan, PI; K. Makishima, Priority-C) is cancelled out. There is no change for observation schedule of Circinus Galaxy on August 14 and before, and also X1543-624 on August 17 and after that. Although this set-up of ASCA TOO observation is too close to the operation date, simultaneous observations with other wavebands are encouraged. F.
