8.3 Observation

XMM-Newton is operated in a pre-planned manner. Observers are not present at the SOC for the execution of their observations.

Depending on the unpredictable activity of the Sun, e.g. solar ``flares'', the start of the execution of scheduled observations may have to be delayed or the execution has to stopped earlier than originally planned in the timeline. Observations may even need to be completely cancelled for this specific scheduled time.
