EAO Eligibility/Funding partners

The JCMT is managed by the East Asian Observatory. The telescope is funded by the East Asian Observatory and a select number of institutions in the UK.

PI Eligibility

PIs of PI observing proposals to JCMT must be from any of the partner East Asian regions (China, Taiwan, South Korea), Indonesia, Malaysia, Thailand, Vietnam or from the universities in the UK and Ireland that contribute to JCMT funding (see lists and definitions below). Otherwise, if you do not qualify by national or institutional affiliation as defined below then you cannot be the Principal Investigator on a JCMT observing proposal. Co-I status is not similarly restricted*. For details of how collaborative projects with investigators from more than one participating regions are allocated, please see here.

* Note: Co-I status is not restricted for PI programs but are restricted for JCMT Large Programs.

Large Program Eligibility

For JCMT Large Programs a Co-I from outside a regional affiliation may not access raw or reduced data (during the proprietary period/prior to publication) but can have access to data products – i.e. source catalogues. Please note that Canadian astronomers can participate in any of the JCMT Large Programs. Finally we warmly welcome Vietnam, Thailand, Malaysia and Indonesian astronomers: these regions now have “observer” status with the JCMT.

For the purpose of applying for observing time with JCMT, the definition of regional affiliation varies amongst the partner nations:



  • Anyone affiliated with an institute in Japan is currently only eligible to propose or act as co-I for Large Program Calls, but is not currently eligible for PI program time – funding for Japan comes from the National Astronomical Observatory of Japan (NAOJ)


South Korea

Contributing UK & Ireland universities

Astronomers from UK and Irish institutions have the following access to the PI queue. Please also note that any astronomer from any institute listed below can also be a member of any Large Program or submit “Urgent” queue proposals.

Unlimited PI access (an unrestricted number of proposals per semester per institution):

2 proposals may be submitted per semester per institution:

1 proposal may be submitted per semester per institution:

Contributing Canadian Organizations**

Please note that while astronomers affiliated with a Canadian institution are encouraged to act as co-Is for projects/proposals targeting the PI project queue, they are not currently eligible to act as the PI for such projects.

** Please note that Canadian astronomers can participate in any of the JCMT Large Programs.
