Notifying of a Cancellation
For returning or swapping time on any telescope,
and for all changes in scheduled 3-meter observing, see also
Policy for Swapping or Cancelling Scheduled 3-m Time

For notifying of a cancellation due to weather or emergency:

Send an email to cancel@ucolick.org ...

When cancelling a night or nights on any Lick telescope, it is essential that observers notify everyone who may be affected by or need to act on the cancellation, both on Mount Hamilton and in Santa Cruz. Observers should send a notice of the cancellation, as far in advance as possible, to the email alias cancel@ucolick.org. Recipients include the mountain technical staff, support scientists, and the people in Santa Cruz responsible for scheduling the telescope, maintaining the posted schedule, and arranging for rooms.

Please note that the cancel@ucolick.org mail alias is reserved for cancelling a night due to weather or emergency. It is not to be used for rescheduling, swapping time, inquiries, or other purposes.

Additionally ...

To insure that the dewar scheduled for use is filled in the observer's absence, it is imperative that he or she confirm with the telescope operations manager or with a support astronomer that the cancellation has been received and that arrangements to fill the dewar have been made.
