JCMT Rapid Turnaround Proposal Submission Opens on October 1st, 2019

The East Asian Observatory is pleased to invite proposals requesting Rapid Turnaround (RT) time at the JCMT. All prospective PIs should review the JCMT eligibility requirements page prior to the preparation and submission of a proposal.

A new RT submission cycle shall begin at the start of every month and close at the start of the next month. Any proposals not yet submitted by this time will be treated as still in preparation, and can be submitted during a subsequent cycle for the same semester. RT requests are limited to a maximum of 8 hours for Band 1 – 4 time requests, but are unlimited for Band 5 time requests. The Observatory shall aim to complete successful RT proposals within six months of their formal approval, after which time they shall be removed from the observing queue (regardless of their level of completion).

All RT proposals submitted shall be peer-reviewed by the proposal creator (or designated co-author) of other proposals submitted during the same submission cycle. The proposal peer review deadlines shall normally be two weeks after the close of the regular end-of-month RT proposal submission deadlines.

By submitting an RT proposal, all proposing teams are committing themselves to providing ratings and brief written assessments of several other proposals submitted for this Call by the corresponding deadline. Any proposing team that fails to provide a full set of reviews for their assigned proposals by the corresponding review deadline shall have their own proposal removed from the review process.

The MSBs for all approved RT projects should be created as soon as possible after their corresponding monthly RT review period has completed, ideally before the end of the month following the proposal submission deadline.

For further details regarding RT proposals, please see the relevant Call for Proposals page here. Any further questions should be directed to helpdesk@eaobservatory.org.
