Dear ASCA users, Please find below the first half of a year of the ASCA observation schedule that is based on the ASCA AO-8 Long Observation Program (targets designated as LOP) for the interval between February 13 and September 6. Scheduling is very tight and flexibility is very small due to small number of targets with long exposure time for each. This make it difficult to get a feasible solution under the conditions of (1) target -sun angle constraint, (2) STT moon constraint, and policies of (3) highly ranked targets earlier, and (4) a single observation for one target. Inevitably, we divided the IRAS 13224-3809 observation and Cas A calibration each into two pointings. Thus at present we have successfully produced the schedule only first half of the AO-8 period, which is now released. After carefull investigation we will release later the second half of a year of the AO-8 observation schedule when we get a feasible solution. All data belong to this LOP are released public immediately when the telemetry data are retrieved and processed, i.e, no PI of the successful proposals has right of exclusive use of data. Every PIs and their collaborators, on the other hand, are expected to take resposibility for conducting their own observations by themselves under assistant of ISAS operation experts. F.
