Call for IAC-Nordic NOT proposals for Semester 2017B

Following the Agreement between IAC and NOTSA for the continued operation of the Nordic Optical Telescope (NOT), 5% of the observing time at NOT is offered for joint IAC-Nordic research programs: this is known as the IAC-Nordic Observing Time. This observing time is aimed at reinforcing the collaboration and synergies between the IAC and the Nordic communities through joint programs. The IAC-Nordic program consists of 7/8 nights per semester, and is offered twice per year through special calls for proposals. Different types of programs can be presented – full or half nights, long term observations – but those proposals looking for strong scientific impact by means of collaboration and synergies between both communities during long periods will be especially considered. Observations will be in visitor mode. Owing to the special nature of the observing time, the conditions for its use differ from those of normal TAC/CAT time. The main features of IAC-Nordic Time are:

  • Any IAC and Nordic research group may apply for this kind of observing time provided that they carry out a joint research and at least one member from each community appears as co-investigator on the proposal. If there are more than four people on the proposal there must be at least two from each community.
  • Proposals must be presented before the deadline announced in the corresponding call for proposals.
  • Proposals shall be made in a format similar to that of normal CAT proposals. See below (or see instructions for further details).

8 nights are available for semester 2017B (October 2017 – March 2018) with any of the NOT core instruments. The deadline for proposal submission is Friday, 26 May 2017, at 17:00 h Canarian time (18:00 h CEST).

Instrumental updates with respect to previous semesters are as follows:

  • A new detector has been installed in FIES, which provides low-fringing and high efficiency in the red. The new CCD (e2V CCD231-42) is about 10% larger than the old one, thus allowing to sample further into the infrared part of the spectrum Current wavelength coverage is 364-911 nm with the high-resolution fiber.
  • A new fiber bundle is planned to be installed in FIES in the coming months. With this new bundle, the radial velocity stability with the high-resolution fiber is expected to improve from 8-10 m/s to ~3 m/s.
  • The SOFIN high-resolution Echelle spectrograph is available. It offers a resolution of R = 27,000-170,000. Applicants that require this instrument are strongly requested to read the NOT web pages, since this is not a common-user instrument.

NOTE: During the IAC-Nordic time in semester 2017B, regular Nordic and CAT Target of Opportunity (ToO) programs are allowed to override IAC-Nordic time (except for time critical observations like planetary transit events, as decided by the joint Time Allocation Committees) according to the following rules:

  • No more than 3 h per night (or 4 h per night, see next) can be overriden: in case of various ToO alerts are received from different programs of a given Time Allocation Committee (TAC), priority will be given to the highest ranked program. In case of competing CAT and Nordic ToO programs which aim for the same science/targets, ONLY JOINT triggers will be accepted. In case of CAT and Nordic ToO programs with different scientific objectives and targets, if triggers are active on the same night, both can be executed up to a maximum of 4 h. The details of how these two later cases can be arranged are to be agreed with the joint TACs.
  • The time observing lost to ToOs will be compensated to the Principal Investigators (PIs) according to the Nordic rules in case of Nordic ToO programs and during the CAT service time (whenever the requested instrument is available) in semesters 2017B and 2018A in case of CAT ToO programs.
  • Any IAC-Nordic PI affected by ToO observations should apply for specific observations to compensate for the observing time lost during the IAC-Nordic time through the NOT Fast-Track Service Program in case of Nordic ToOs and through the CAT Service form in case of CAT ToO programs (in the CAT form, please indicate clearly that your application is to compensate the time lost to ToO during the IAC-Nordic time, and provide the ToO program code).
  • The list of approved ToO programs are available on Nordic ToO programs (click on the corresponding semester and go to the end of page) and CAT ToO programs.
How to submit

The IAC-Nordic observing time must be requested through the IAC’s CAT online system in the same way as standard CAT proposals, but selecting the IAC-Nordic time in the list of “Special Agreement Time”. The scientific rationale must be prepared using the specific IAC-Nordic templates available in Latex or Word styles. Proposals will be evaluated by a joint IAC-Nordic committee. See instructions for further details.


Any publication originating from this kind of observing time shall include an acknowledgement along the following lines: “Based on observations made with the Nordic Optical Telescope operated on the island of La Palma by NOTSA in the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofísica de Canarias under the joint IAC-Nordic Observing Time program”.
