Supplementary Call for Proposals in Semester 16B

For the second successive summer, we have experienced unusually poor weather at the start of the B-semester, and we are facing a period of 7 weeks without SCUBA-2 in October and November, as it undergoes important maintenance. The combination of these events has severely impacted our supply of approved band-3/4 heterodyne programs.

We therefore invite new proposals to observe targets with 20h < RA < 04h with HARP and/or RxA, for immediate assessment, approval and execution.

See here for details; where the ‘Semester’ in question is called ’16X’.

You can reach the proposal handling system, Hedwig,  and find complete details of this Call at:


Any further questions should be directed to our helpdesk:


If this is your first visit to Hedwig, you should go to ‘Log in’ and generate an account. There is a ‘Help’ facility at the upper right corner, and individual Help tags at many other places.

This Call for Proposals closes on the 11th of October 2016. We welcome submissions now.

JCMT workshop, Shanghai, October 16th 2016

The JCMT would like to announce that the Shanghai Astronomical Observatory will hold 1-day workshop on JCMT data reductions and analysis on Oct. 16 at SHAO in Shanghai. JCMT staff, Dr. Harriet Parsons and Dr. Mark Rawlings, will give these tutorials.  The agenda can be found below.

This workshop is scheduled before JINGLE team meeting in Shanghai (Oct. 17-18) and MALATANG team meeting in Nanjing (Oct. 19-21) as a united conference. We aim to open this tutorial to all interested researchers and students, and high priority will be given to members of JINGLE, MALATANG and other JCMT large programs due to space limitation.  If you are interested to attend, please contact Ting Xiao (xiaoting@shao.ac.cn) as soon as possible to help us get a rough head account.

Agenda for the workshop on Oct. 16:

Morning session:

  • introduction to STARLINK
  • introduction to HARP and RxA3m
  • Heterodyne beginner
  • Heterodyne advanced

Afternoon session:

  • introduction to SCUBA-2
  • SCUBA-2 basic
  • SCUBA-2 advanced

In addition if requested we could cover any of the following (time permitting):

  • Hedwig session – Proposal submission to the JCMT
  • JCMTOT – how to submit JCMT project MSBs
  • POL-2 introduction and basic data reduction in an extended session
  • General JCMT project support for existing users

Call for Proposals 17A

The East Asian Observatory is happy to invite PI observing proposals for semester 17A at JCMT (for details see here).

Semester 17A runs from 01 February 2017 to 31 July 2017. You can reach the proposal handling system, Hedwig,  and find complete details of this Call at:


Any further questions should be directed to our helpdesk:


If this is your first visit to Hedwig, you should go to ‘Log in’ and generate an account. There is a ‘Help’ facility at the upper right corner, and individual Help tags at many other places.

The 17A Call for Proposals closes on the 15th of September 2016.

NEW: The East Asian Observatory invites requests for Urgent Observing at any time – and you can now submit these request via a special Call in our Hedwig proposal system. You can find details here.

Constraints and guidance on applicant eligibility, the available instrumentation, the required content of the proposal, and other aspects of the proposal are as described in the Call for Proposals for the current semester – except as itemized below.

Urgent Requests should clearly describe the following:
1. The urgency for the observations, and why a response to the regular, semi-annual Call for Proposals is/was inappropriate.
2. The time span over which observations may be made or the specific times at which they must be made.
3. The timescale for analysis of resulting data and for publication thereof; which ought to be proportionately urgent . . .

The above information should appear in the Scientific Justifications section of the proposal; itemized as above, please. If approved, proposals will be graded with respect to the approved projects in the current semester and executed via JCMT’s Flexible Observing scheme.

Status of SCUBA-2

SCUBA-2 was recently returned to service after a 5-week-long absence due to a partial cryogen blockage. It has been returned to full service, despite requiring alternative operating conditions because of a problem diagnosed with one of the Pulse Tube Coolers. This issue has left the instrument filters at temperatures that are fractionally warmer than normal. SCUBA-2 operation will be maintained until October 5, when it will be removed from the telescope to replace the PTCs and also install new optical filters which we expect to improve the instrument performance. SCUBA-2 return to service is expected on or before November 24.

We apologize for the inconvenience and will keep you updated as to our progress.

Face-to- face workshop for “SAMPLING-TOP- SCOPE”, December 14-16, Beijing -1 st announcement

The Planck satellite has discovered more than ten thousand Galactic cold clumps, the so-called “Planck Galactic Cold Clumps” (PGCCs). The PGCC catalog, covering the whole sky, hence probes wildly different environments, and represents a real goldmine for investigations of the early phases of star formation. After the successful start of the pioneer survey with the PMO 14-m telescope, we are conducting a joint survey (“SAMPLING-TOP- SCOPE”) towards 1000-2000 PGCCs with the SMT 10-m, TRAO 14-m, and JCMT 15-m telescopes. “SAMPLING” (SMT “All-sky” Mapping of PLanck Interstellar Nebulae in the Galaxy) is an ESO public survey inJ=2-1 12CO/13CO emission using the SMT 10-m telescope. “TOP” (TRAO Observations of Planck cold clumps) aims at an unbiased J=1-0 12CO/13CO survey of 2000 Planck Galactic Cold Clumps with the Taeduk Radio Astronomy Observatory 14-meter telescope. “SCOPE” (SCUBA-2 Continuum Observations of Pre-protostellar Evolution) is a legacy survey using SCUBA-2 at the James Clerk Maxwell Telescope (JCMT) of the East Asia Observatory (EAO) to survey 1000 Planck galactic cold clumps at 850 micron. We are also actively developing follow-up observations towards the SCUBA-2 cores detected in “SCOPE” with other ground-based telescopes (e.g. KVN 21-m, NRO 45-m, Effelsberg 100-m, Arecibo 300-m, SMA, and ALMA). Through these observations, we will study how dense cores form and how star formation varies as a function of environment, the universality of filaments in the cold ISM and their roles in generating dense cores, the existence of a density threshold for dense core formation, how dust properties change in different environments, and how dust properties affect the chemical evolution of dense cores.

To promote collaborations among team members on using the survey data for science, we will hold a face-to-face workshop on Dec. 14-16 at Peking University, Beijing, China. To indicate your interest in attending the workshop, please sign your name on the following doodle page:

JINGLE meeting Oct. 16-18 in Shanghai – 1st announcement

The JINGLE Team meeting and JCMT Data Reduction & Analysis Workshop will be held on Oct. 16-18 in Shanghai at the Shanghai Astronomical Observatory, China.

JINGLE (The JCMT dust and gas In Nearby Galaxies Legacy Exploration) began in Dec. 2015, and the overall program completion is about 1/4.  Team members are encouraged to join the team meeting on Oct. 17-18 to discuss the survey status and plan, data reduction and evaluation, data analysis, and most importantly the scientific projects based on survey data.  The JINGLE meeting and MALATANG meeting are scheduled in one week for a united conference focusing on two main themes: 1) cold gas and dust in large sample of galaxies and 2) dense gas and gas/dust in the nearest 20+ brightest infrared galaxies.

Before the JINGLE team meeting, we will have 1-day tutorial on JCMT data reductions and analysis provided by JCMT staff.  We will open this tutorial to all interested researchers and students.  But due to space limitation, high priority will be given to JINGLE members and members of JCMT large programs .
