Announcement
We are honored to announce the 2nd Call for Proposals (CfP) of the 40-m Thai National Radio Telescope (TNRT) at Thai National Radio Astronomy Observatory (TNRO) in Chiang Mai, the northern part of Thailand, as Cycle 1. This observatory with the 40-m TNRT is a national facility in Thailand, which is operated by National Astronomical Research Institute of Thailand (NARIT, Public Organization). In this cycle 1, proposals are invited to request time on the 40-m TNRT, according to the following details.
Deadline: 31st January 2025, 16:00 UT
Language: The proposals are required to be submitted in ENGLISH ONLY
Open-use Period and Total Observing Time
- Period: 1st March 2025 - 31st August 2025
- Total observing time: 1000 hours / period, at maximum

What's Resident Shared Risk Observing (RSRO) Style ?
This style applies if the proposals request for observation modes other than spectral line modes for the main and satellite lines of OH masers (i.e., for 1612, 1665, 1667 and 1720 MHz). In other words, this style applies to observation modes under commissioning. This style provides an open-use observation time to proposers, as an incentive for contributing to a part of the TNRT development and its commissioning activities, such as,
- Cooperate to adjust software and polish the pipeline up for the data reduction/calibration,
- Documentation of such adjustment/polishing-up,
- Joining applicant's operations,
- Feedback for contributing to the commissioning (including forthcoming observation modes),
- etc.
If your proposal fits with the RSRO style, we request the principal investigator (PI) of a proposal to come to NARIT and/or the TNRO site (Huai Hong Khrai Royal Development Study Centre, Doi Saket District, Chiang Mai, Thailand) and to contribute the aforementioned activities for addressing RSRO style. If PI is not available, there may be room for replacing by a co-investigator to address this RSRO request.
In proposals, the technical justification should identify the personnel who will be involved in the effort and which activities are interesting to the candidate. In addition, it is better to describe how their expertise will be helpful to address the critical priorities of the TNRT development in their proposal, and better to clarify the proposed dates of the residency as a reference for matching to the TNRT development / commissioning planning.
Privilege for Students
Students have privilege for their proposals being positively accepted. See section "Privilege for Students" for more details.
