ALMA is accepting proposals for Director’s Discretionary Time

Submissions of Cycle 4 DDTs are accepted through the end of Cycle 4. In addition, starting September 22, 2017, PIs can also submit DDTs for Cycle 5. This allows PIs to start taking advantage of the C43-10 configuration which is available starting October 1, 2017. The general guidelines and submission instructions for Cycle 5 DDT proposals are the same as for Cycle 4:

  1. Proposals requiring the immediate observation of a sudden and unexpected astronomical event;
  2. Proposals requesting observations on a highly competitive scientific topic, motivated by developments that have taken place after the regular proposal submission deadline;
  3. Proposals asking for follow-up observations of a program recently conducted with ALMA or any other observing facility, where a quick implementation is expected to provide breakthrough results.

DDT observations will be conducted on a best effort basis, with priority given to the completion of the full ALMA capabilities.
