EUROPEAN SOUTHERN OBSERVATORY La Silla - Science Operation Department

Operational guidelines for GROND (update 19. Jun 2010)

• all ESO time slots (both visitor and service)
• MPG time
• Brazilian time (note that compensation for Brazilian visiting observers is covered by the official agreement).
• Chilenian time

1. The GROND RRM system state will be operated in cooperation with an ESO staff member (TIO and/or astronomer) and a GROND observer.
2. GROND, in principle, like any other instrument, can be operated from sunset to sunrise. Saftey requires to terminate GROND observations, and to start the telescope dome closing procedure at latest
• 12 min before sunrise if the telescope is pointing to the EAST
• 2 min before sunrise if the telescope is pointing to the WEST
3. The authority to allow or cancel an actual telescope preset requested by the RRM system ("30 sec countdown") is entirely with the 2.2m telescope operator.
4. After each RRM trigger that causes the telescope to preset ("successful trigger"), the responsibility to operate the instrument is entirely with the GROND observer, until he hands over control of the telescope back to the TIO.
5. For each trigger, a Remedy ToO ticket is submitted automatically by the GROND system. After the observation of that trigger, it is important to update the corresponding Remedy ticket (LTOO-...), and fill the field "Time Used by trigger".
6. The time used for GROND observations is accounted for in the NightLog, observing type "visitor". All time losses (weather, technical downtime etc.) are reported as usual. A detailed logging of individual OBs ("nightly activities") is not implemented yet.
7. GROND observers may use car #102 (in case of doubts check with logistics, J. Duk).

• The GROND observer is reachable with beeper *62
• The GROND runID for GRB in the ToO ticket system is 087.-9099(A).
