Cycle 11 Call for Proposals (CfP: 1 November 2023 - 15 May 2024)
Proposal Deadline: 11:59 Hours (Bangkok Time), 31 August 2023
Proposals are invited to request time on the 2.4m Thai National Telescope (TNT) and on the 1m telescope at the Thai National Observatory (TNO) (TNO-1m).
- Cycle 11: for the 2.4m TNT (public) and the TNO-1m (public)
Key Dates:
CfP opens: 01 August 2023
Deadline: 31 August 2023
Observation Period: 01 November 2023 - 15 May 2024
The proposal must be submitted in ENGLISH ONLY.
Eligible proposers
The call for the 2.4m TNT and TNO-1m is open to all Thai and Internationally affiliated astronomers.
Proposals with at least ONE Thai-affiliated CoI (or PI) are strongly encouraged. Non-Thai PI/ proposals can be submitted in the usual way. However, if a Thai-affiliated and a non-Thai-affiliated proposal are ranked equally, preference will be given to the Thai-affiliated proposal.
Furthermore, in deciding on proposal rankings, the Time Allocation Committee (TAC) will take into account the publication record and the impact of the proposers with previous NARIT telescope time allocations.
The proposals will be reviewed by a panel of professional astronomers and will be ranked on the basis of their scientific scores by TAC nominated by the NARIT Director. The technical feasibility of the proposals will be reviewed by the NARIT Division of Observatory Operations (DOO).
What's new in this Cycle?
- TNO-1m is now being offered to all the PIs . Please go to the TNO-1m section for detailed information.
- A commercial spectrograph (eShel) is now available for TNO-1m. Please contact somsawat@narit.or.th if you are interested in using this instrument. In addition, in the “Instrumentation” section of your proposal, please select “Visitor Instrument” and specify “eShel”.
For observation/details of ULTRASPEC at TNT, contact: Puji Irawati (puji.irawati@narit.or.th)
- ARC 4K: New set of filters are available now. For observation/details of this instrument, contact: proposal@narit.or.th
- MRES: There have been reports of flat lamp intensity problems. Users are advised to check the exposure time when taking flat calibration with MRES. For observation/details of MRES, contact: David Mkrtichian (davidmkrt@gmail.com)
- Multiple instruments
Applicants of TNO Cycle 11 can request multiple instruments in their proposal. The desired instrument(s) can be selected in the instrument section of the online submission form.
Note that the applicants have to provide detailed information on the needs of using multiple instruments for their proposals.
Important Notes
- The TAC will be putting a strong emphasis on the past publication record () of PIs and projects previously allocated time on the TNT during the past cycles. The proposer of an application under these conditions must take good care in filling out sections C) and G) in the "Description of the proposed project" of the online form.
- Observation requirements in section B) must be provided as complete as possible. Proposals that fail to provide the observation requirements may be rejected.
- There will be no DOO staff to assist the observation with the TNO-1m.
- Observers are expected to contact NARIT staff to prepare their visit at least one month in advance of their run. They are expected to cover their expenses for travel to the TNT Doi Inthanon site as well as for local accommodation and subsistence. A set of Instructions for Visiting Astronomers are available to facilitate the logistics of the visit. Visitors are strictly required to fill an End of Run report and submit it to the NARIT staff within one week after the end of observations.
- PIs are required to read the instructions very carefully before making the applications. PIs must ensure that the applications are filled out truthfully and as accurately as possible. PIs are responsible for the content in the proposal, any misuse of NARIT facilities, data, or false information may result in being disqualified from the application process or any scheduled time slot.
- Target of Opportunity (ToO) application can be made outside of normal active CfP periods and can be submitted at any time.
- Titles and Abstracts of all the proposals we received during this and later cycles will be published on the NARIT website.
- Metadata of the data taken during this and later cycles, except the ULTRASPEC GTOs, will be made available on NARIT public scientific data archive. However, the actual data themselves will be kept proprietary for a period of ONE year after the end of the cycle in which the data were taken. After this, the data may be queryable by the public or any user of the NARIT scientific data archive. If for any reason, e.g. nature of the scientific campaign, etc., PI may request an extension of the proprietary period which the TAC will consider on a case by case basis.
