Every week an observing request (OR) list is generated from the long term schedule (LTS) target list for that week, plus some unconstrained (pool) targets. This OR list is over-subscribed to allow an efficient schedule to be generated. The short-term schedule consists of those targets from the OR which will actually be observed; those targets not scheduled are then returned to the pool to be selected for future weeks.
The short-term schedule is the plan for a week's observing time. If there are no interruptions, all observations will be carried out close to the times listed. However, schedules can be interrupted by TOO observations, by solar-flare particle events, and by operational difficulties. This schedule is not a guarantee that the observation will occur when indicated.
There is a link to previous weeks' short-term schedules at the bottom of this page.
