  • ToO interrupts should be issued only for observations that are time critical. Non-time-critical followup observations should be pursued through other means.

  • ToO PIs may not specify observing conditions under which the ToO observations are made; either the ToO observations are triggered or they are not. If a called ToO is clouded out then the time is charged, just as if the observations were made. The same is true of instrument/telescope failures.

  • ToO observations are authorized only for NOAO assigned telescope time. Observing runs assigned by the Chilean TAC may only be interrupted upon the consent of the scheduled observer.
