How can I know precisely on what dates my Service Mode observations will be executed?

A key feature of the flexible scheduling approach followed at the ESO Observatories is that Service Mode Programmes do not have definite dates assigned to them. Rather, they are executed according to the external observing conditions, some of which are unpredictable, like the sky transparency or the seeing. Only in this way it is possible to ensure that each of the many programmes approved every semester in Service Mode is executed under the conditions that are necessary for its scientific goals.

The Principle Investigators and their Phase 2 and/or data delgate(s) can subscribe to receive e-mail notification whenever one of their OBs has been executed. To subscribe login to the (Garching Night Log Tool) gNLT overview page using your User Portal credentials.
