Dear ASCA users, This is the last ASCA observation schedule of this year, and we close the ASCA AO5-cycle observation by the last target N103B (PI: R. Petre). All the priority-C targets that are currently unobserved and unscheduled are cancelled out. Priority-A and -B targets for that observations are not scheduled or not completed are carried over to the period of AO6. Observations of AO6 targets will start from the beginning of the next year. If there are time critical targets in AO6 that must be done in December, currently scheduled priority-C targets will be replaced. F.
