These two workshops were successfully held in July 22-26, 2024 (webpage).
We are pleased to announce the East Asian (EA) ALMA Science Workshop 2024-Korea. The EA ALMA community of Japan, Taiwan, and Korea has got together every year to share new results and to promote collaborations. This year we will come together in Korea again, particularly at the Siheung campus of the Seoul National University on July 22-24, 2024, which is near the Incheon international airport.
ALMA passed over 10 years last year since it was inaugurated on March 13, 2013. So far ALMA has been delighting and enlightening us with numerous fantastic results. Now ALMA also has an excellent sibling, JWST. In this workshop, we will have a chance to listen to brief histories of EA ALMA 10 years, as well as nice scientific results from large and PI programs of ALMA. Also, we hope to see many comprehensive results jointly obtained with other facilities like JWST and VLA. Any astronomers who are interested in ALMA, regardless of having their own ongoing ALMA projects or not, are welcome to join.
This year, a new workshop, Data Analysis Workshop, is scheduled after the Science Workshop. Participants will work in groups to analyze ALMA archival data on specific topics, guided by experienced supervisors. Through group work, we aim to promote closer interaction and facilitate skill development, particularly among young members. Based on the preliminary survey, five topics will be offered: "multi-band", "polarization", "self-cal", "TP combining", and "basics". If there are more applicants than our capacity of ~25, we give priority to those with early careers, maintaining the regional balance.
Further updates and details will be continuously added to the workshop's webpage. Please keep an eye on https://alma.kasi.re.kr/EA_ALMA_2024/ for the latest information.

East Asia ALMA Joint Session by the JAO Proposal Handling Team
Townhall meeting
The ALMA group at the Korea Astronomy and Space Science Institute (KASI) is organizing a workshop for the preparation of ALMA observation proposals. This workshop aims to provide tips on securing observation time. Participants will have the opportunity to organize the content of their proposals and receive advice from mentors.
The workshop will be conducted in two sessions, with a two-week interval between them. The first workshop includes lectures on how to write successful proposals. Additionally, participants will also have the opportunity to hear about the experiences of users who have successfully secured observation time. Over the following two weeks, participants will prepare the outlines of their own proposals based on guidelines. In the second workshop, all participants will present the overview of their observation proposals and receive feedback from mentors.
Please note that some of the lectures and presentations will be conducted in Korean to encourage active participation from students. Additionally, some of the content covered in the first workshop will be presented at a town hall meeting in March.
For these reasons, the workshop is open only to students and researchers who plan to submit observation proposals this year. Applications for participation can be submitted until January 19th through this link.

Note that the overall schedule may be modified depending on the outcomes of the proposal review process and the proposal pressure in the different configurations. While configurations C-1 through C-8 (with maximum baselines between 0.16 and 8.5 km) will be offered every cycle, users should note that configurations with baselines longer than 13 km (C-9 and C-10) are scheduled for Cycle 7 and 9 but not Cycle 8.
The Schedule is provided at the following link.
In Cycle 7, ALMA will offer an ACA stand-alone Supplemental Call for Proposals. It is anticipated that the Supplemental Call will be released on 3 September 2019 with a proposal deadline on 1 October 2019. Since the Supplemental Call will follow the Main Call by five months, the Supplemental Call will maximize the scientific output of the ACA by allowing more timely science to be proposed. Proposals accepted in the Supplemental Call will be scheduled for observations between January 2020 and September 2020.
The science portal includes a more detailed description
of the Supplemental Call.
The Joint ALMA Observatory (JAO) will start the next cycle of observations (Cycle 7) in October 2019.

KASI has been developing a wide band ALMA receiver covering the frequency range of the ALMA band 7 and 8 (275 to 500 GHz) since 2015 in cooperation with the NAOJ. The GPU spectrometer also has been developed as a backend of recievers for the ASTE telescope as well as for the ALMA TP array, which has been approved by the ALMA board committee in 2017. The researchers of the KASI and the NAOJ have been conducting regular face-to-face meetings for the effective cooperation of development projects. This year in 2018, there were two face-to-face meetings during January 16-17 and November 20-22 in Korea. The detailed programs can be found in the following links.

Announcement of 3mm VLBI in Cycle 5
It is expected that phased ALMA will participate in some GMVA observations during ALMA Cycle 5 (Oct 1 2017 - Sept 30 2018; see the ALMA Cycle 5 Pre-announcement). The number of ALMA dishes possible in the phased array is likely to be 35 - 43 (but see below). ALMA will not be in a configuration suitable for VLBI during GMVA Session II 2017. GMVA session dates during Cycle 5 are not yet fixed, but Session I in 2018, which is likely to be in March or April, should provide an opportunity for GMVA + ALMA observing. GMVA Session II in Fall 2018 may also overlap with ALMA Cycle 5 in a configuration suitable for VLBI.
Any GMVA proposal requesting phased ALMA during Cycle 5 must be submitted via the NRAO PST at the February 1, 2017 deadline.
Proposers should:
(1) Specify "ALMA" in the Other Stations text field in the PST. (2) Select the default GMVA 3mm observing mode of 2 Gbps, dual polarization. (3) Specify the amount of time and GST range(s) needed for ALMA separately, either in Session Constraints or Comments, or in the Technical Justification.
Announcement of upcoming availability of ALMA Solar SV data
New installments of Science Verification data are planned for release on 18 January 2017. The data release will contain observations of the Sun obtained during the Solar commissioning campaigns in 2014 and 2015. The release will contain mosaics and single pointing observations in Band 3 and 6 with the 12m, 7m and total power arrays. Details of the observations will be listed on the Science Verification web page.
The Joint ALMA Observatory (JAO) will start the next cycle of observing (Cycle 5) in October 2017. A Call for Proposals with detailed information on Cycle 5 will be issued in March 2017, with a deadline for proposal submission in April 2017.

A new image from ALMA, the Atacama Large Millimeter/submillimeter Array, reveals extraordinarily fine detail that has never been seen before in the planet-forming disc around a young star. ALMA’s new high-resolution capabilities were achieved by spacing the antennas up to 15 kilometers apart. This new result represents an enormous step forward in the understanding of how protoplanetary discs develop and how planets form. For details about the ALMA image of HL Tau click here
KASI, Korea
Tokyo International Forum, Tokyo, Japan
On August 17, 2014, the National Institutes of Natural Sciences (NINS) of Japan and the Korea Astronomy and Space Science Institute (KASI) signed an agreement concerning the operations and development of ALMA. With this agreement, Korea officially joined in the East Asia ALMA consortium, whose current members are Japan and Taiwan.
Japan and Korea have promoted active collaboration in the field of astronomy. In 2001, the two countries made a successful VLBI observation for the first time by linking the 45-meter radio telescope of the Nobeyama Radio Observatory (NRO) of the National Astronomical Observatory of Japan (NAOJ) and the 14-meter radio telescope of the Taeduk Radio Astronomy Observatory of Korea. The following year, NAOJ and KASI officially signed an agreement to further strengthen the collaboration. And a decade later, in March 2012, NAOJ and KASI signed a Memorandum of Understanding concerning the collaboration of ALMA.
This agreement enables Korea’s participation into the ALMA project as well as their contribution to the operations of ALMA and development of new instruments. It is expected that this agreement will enhance the cooperation of two countries in astronomy and greatly promote the diversity and innovativeness of East Asian astronomical researches.
Korean ARC Node is to provide support service to the ALMA user community in Korea
