Director's Discretionary Time Observations
Director’s Discretionary Time (DDT) can be requested for time-critical observations that cannot plausibly be scheduled for the regular proposal cycle. These types of proposals might be appropriate for the follow-up of newly-discovered unexpected transient phenomena or when developments since the last proposal cycle make a time-critical observation necessary. They are also appropriate for timely follow-up of new discoveries that will provide a critical link in the understanding of the phenomena.
