Call for Proposals – for Semester 25A

The East Asian Observatory is now accepting proposals for the Principal Investigator (PI) queue for Semester 25A at the James Clerk Maxwell Telescope (JCMT). Proposal submission is via the JCMT proposal handling system, Hedwig. For full details, and for proposal submission, please see

https://proposals.eaobservatory.org/

The 25A Call for PI Proposals closes on November 9th 2024 00:00 UTC time. The Hedwig system permits the submission (and repeated re-submission) of proposals until this deadline.

If this is your first time using Hedwig, you should use the ‘Log in’ button to generate an account. There is a Hedwig ‘Help’ facility at the upper right corner of each page, and individual Help tags in many other places. Note that Hedwig also allows a user to create copies of their previous approved proposals that were not completed (‘Continuation Request’), in order to simplify the process of proposal resubmission.

Proposers might be interested to note the proposal pressure in terms of RA and DEC. The figure below shows the distribution of target RA proposed in the past under Semester A. When allocating time the TAC is mindful to ensure that time is awarded across a range of RAs.

Please contact us at helpdesk@eaobservatory.org if you have remaining questions about either of the above Calls for Proposals.

 

 

Call for proposals for semester 2024B

The East Asian Observatory is happy to invite PI observing proposals for semester 24B at the JCMT. Proposal submission is via the JCMT proposal handling system, Hedwig. For full details, and for proposal submission, please see:

https://proposals.eaobservatory.org/

The 24B Call for Proposals closes on the 17th of March, 2024 (2024-03-17 00:00 UT).

If this is your first time using Hedwig, you should ‘Log in’ and generate an account. There is a Hedwig ‘Help’ facility at the upper right corner of each page, and individual Help tags in many other places. Please contact us at helpdesk@eaobservatory.org if you have remaining questions.

Hours available

The median award of hours to successful program is 14 hours. This ranges to fewer hours in Grades 1-3 due to pressure and weather availability and more in Grade 4/5. Awards range in hours from 1-80 hours in total.

Instrumentation availability

All instrumentation are expected to be available.

24B RA Pressure

Proposers might be interested to note the proposal pressure in terms of RA and DEC. The figure below shows the distribution of target RA proposed in the past under Semester A. When allocating time the TAC is mindful to ensure that time is awarded across a range of RAs.

 

Weather

Proposers should also be mindful of the historical fraction of time in each weather Grade in particular noting the wide variation in ours per weather Grade obtained in any one semester.

 

The Expanding Partner Program

PIs from Malaysia, Vietnam, Indonesia, India, Brazil and Argentina are welcome to apply for a limited amount of time (<9 hours per program this time constraint is not limited in Grade 5 time) under the “Expanding Partner Program” – a program to encourage astronomers from new JCMT partners to make use of the JCMT.

*** Completion of any science program awarded time is not guaranteed. Approval reliant upon the program being technically feasible, without clashing with existing proprietary data. Data collection is dependent on weather/instrument/queue pressures with adjustments in line with recommendations by the TAC. Under the “Expanding Partner Program” priority will be given to new users of the JCMT.
