Observing with ALMA

The ALMA Director solicits proposals for observing time with the Atacama Large Millimeter/submm Array.  The solicitations shall be done through a Call for Proposals, announced in the Proposing section of the ALMA Science Portal. Supporting documents and associated software is made available to the community at the time of the call.

You cannot submit proposals for the regular Cycle now.
Please wait for the next announcement of observing time which will be released around April 2016.
For your convenience you can look at the historic Cycle 4 Call for Proposals.

Proposals for use of Director's Discretionary Time (DDT) must currently be submitted using the Cycle 2 version of the ALMA Observing Tool available through DDT proposal page.
