ALMA is now accepting Cycle 7 DDT proposals

Mar 18, 2021

In anticipation of resuming limited science operations in March 2021, ALMA is once again accepting proposals for Director’s Discretionary Time (DDT). The general procedures to submit a DDT proposal are described on the Science Portal.

ALMA is currently in the return-to-operations phase after suspending observations because of the pandemic. During this phase, a reduced number of ALMA antennas on the 12-m (at least thirty-two antennas in a C43-4/C43-5 configuration) and 7-m (at least eight antennas) arrays will be available. PIs should therefore consider that the DDT projects may be executed with fewer than the nominal number of Cycle 7 antennas. If the observations can only be performed with the nominal antenna numbers, this should be explicitly stated. Any approved DDT proposals will be observed on a best-effort basis, with priority given to completing the return to operations in a safe manner.
