An international team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has witnessed a cosmic weather event that has never been seen before — a cluster of towering intergalactic gas clouds raining in on the supermassive black hole at the centre of a huge galaxy one billion light-years from Earth. The results will appear in the journal Nature on 9 June 2016.

Information related to the new version of the ALMA Observing Tool (OT) for preparing Cycle-4 proposals, the Project Tracker as well as a clarification on full polarization capabilities are now available in
this link to the ALMA General News.
Several clarifications related to the Large Program Policy for Cycle 4 are now available in

The Joint ALMA Observatory (JAO) has recently identified a problem affecting selected programs from Cycles 1 to 3 where positional offsets or mosaics were used to set up Scheduling Blocks in the ALMA Observing Tool.
Read all the details in this link to the ALMA General News.
The Joint ALMA Observatory (JAO) has examined the distribution of remaining QA2 non-Pass executions for the 5km array (C36-7) and has determined that given the distribution, the observatory will not revisit the 5km array near the end of the Cycle 3 observing season; instead preferring to revisit the current array C40-3 (which is C36-2/C36-3 which is oversubscribed at some LST intervals which are becoming daytime now but will be nighttime by the end of the cycle). This will improve the overall completion at the expense of a few fewer executions and completions in the 5km array configuration. As a result of this decision, 10 A ranked executions will roll over into next year for the 5km configuration.
For B ranked observing programs, those programs are effectively cancelled as “ObservingTimedOut”. These data will be evaluated through the standard QA2 process with the anticipation that most will end up as QA2 SEMIPASS.
According to the current policy, PIs of A ranked proposals (those that will carry over to Cycle 4) may request delivery of the raw ASDMs from scheduling blocks already completed from these programs through their ALMA Regional Centers because the programs will have no chance of being observed within the next 90 days. This can be done by submitting a ticket to the “Archive and Data Retrieval” department of the ALMA Helpdesk (https://help.almascience.org). Any and all additional questions should be submitted through the ALMA Helpdesk.
The ALMA Director, on behalf of the Joint ALMA Observatory (JAO) and the partner organizations in East Asia, Europe, and North America, is pleased to announce the ALMA Cycle 4 Call for Proposals (CfP) for scientific observations to be scheduled from October 2016 to September 2017.
It is anticipated that up to 3000 hours of the 12-m Array and up to 1800 hours of the Atacama Compact Array (ACA), also known as the Morita Array, will be available for successful proposals from Principal Investigators (PIs) in Cycle 4. Proposals must be prepared and submitted using the ALMA Observing Tool (OT), which is available for download from the ALMA Science Portal (www.almascience.org). Proposals will be assessed by competitive peer review by a single international review committee.
ALMA Cycle 4 proposal submission will open at: 15:00 UT on Tuesday 22 March 2016
The ALMA Cycle 4 proposal submission deadline is: 15:00 UT on Thursday 21 April 2016
ALMA provides continuum and spectral line capabilities for wavelengths from 0.32 mm to 3.6 mm, and for angular resolutions from 0.024†to 3.7†on the 12-m Array. Cycle 4 offers several new technical capabilities, including Solar, millimeter-wavelength Very Long Baseline Interferometry (mm VLBI), spectral-line linear polarization, and ACA stand-alone observations. In addition, for the first time ALMA will accept Large Proposals, which are programs that request more than 50 hours of time on the 12-m Array or the ACA in stand-alone mode to address key scientific questions. Up to 15% of the available time will be allocated to Large Proposals.
For comprehensive information of this Cycle 4 Call for Proposals please consult the ALMA Science Portal.
The call for 1-mm Very Long Baseline Interferometry (VLBI) proposals to use phased ALMA at Band 6 in Cycle 4, in collaboration with the Event Horizon Telescope Consortium (EHTC), will be released to coincide with the ALMA Cycle 4 Call for Proposals in March 2016. The EHTC is expected to comprise the Submillimeter Array, the James Clerk Maxwell Telescope, the Submillimeter Telescope, the Atacama Pathfinder Experiment, the South Pole Telescope, the Large Millimeter Telescope Alfonso Serrano, the IRAM 30m telescope, and an antenna from the Northern Extended Millimeter Array.
The same scientific justification must be submitted in response to the ALMA and VLBI network calls. NRAO will facilitate this for the 1mm VLBI call by having proposers submit a copy of their ALMA Cycle 4 proposal in response to the 1mm VLBI call, approximately one week after the ALMA proposal deadline in April.
Further details, along with technical information for phased ALMA and the EHTC, will be made available with the 1mm VLBI Call for Proposals. It is expected that observing will take place in March or April 2017, when ALMA will be in a compact configuration suitable for efficient phasing.
A new Band 9 receiver was installed inside the Swedish ESO PI receiver for Apex (SEPIA) at APEX in early February. This receiver, built by NOVA, is a copy of the ALMA Band 9 receiver, and covers frequencies from 600 to 722 GHz. After on-sky commissioning in late March, Science Verification (SV) observations are planned. Ideas for SV, which will allow testing of a large variety of observing modes for this new receiver, are encouraged.
The Call for Proposals for SEPIA Band 9 SV and further details can be found at the Call for Science Verification Proposals pagefor SEPIA Band 9.
As indicated in the Pre-announcement for the Cycle 4 Call for Proposals, the Joint ALMA Observatory (JAO) will accept proposals for Large Programs for the first time in Cycle 4. An announcement which provides guidelines to prepare a Large Program proposal can now be found on the ALMA Science Portal.
Definition of a Large Program
Large Programs are defined as projects that request more than 50 hours of observations with either the 12-m Array or the Morita Array (a.k.a. the ALMA Compact Array, or ACA) in stand-alone mode. Large Programs for the 12-m Array may include ACA for short-spacing observations as needed.
A Large Program can only request standard observing modes. The standard observing modes offered in Cycle 4 are listed in the Pre-announcement for the Call for Proposals. Requests for Target of Opportunity and time-critical observations are not permitted in Large Programs in Cycle 4.
