Montsec Observatory Call for Proposals 2026B

[Kike Herrero Casas]

Montsec Observatory (OdM-IEEC) Call for Proposals | Semester 2026B

Dear SEA members, The Montsec Observatory (OdM-IEEC) opens a Call for Proposals to apply for open observation time at the 0.8m Joan Oró Telescope (TJO) with the MEIA2 imager and the ARES spectrograph. In addition, in collaboration with the Fabra Observatory of the RACAB, the OdM opens a Call for Proposals to apply for observation time at the 0.5m Fabra-ROA Montsec Telescope (TFRM), which is a modified Baker-Nunn Camera.

Proposals can be submitted until: Friday, 15 May 2026 (22:00 UTC) For observations from 01 July to 31 December 2026 Submit via MUR System

Information for regular TJO proposals General Individual proposals are expected to request a maximum of 100 hours of observation time for the TJO. MEIA2 imager MEIA2 is a 2k x 2k back-illuminated camera that provides a 12.3' x 12.3' Field of View (FoV) and a 0.36"/pixel resolution. More info. The imager includes a filter wheel containing broadband Johnson-Cousins (UBVRcIc) and SDSS (griz), and narrowband Hα (650-664nm) filters. In addition to raw images, reduced data with astrometry and standard photometry are provided.More info. ARES spectrograph ARES has a R=12000 spectral resolution and can operate with two different VPHs that provide two different spectral windows: 495-530nm (including the MgI triplet) 630-673nm (including the Hα line) A new automatic data reduction pipeline for ARES is available and operating since March 2025. Extracted and calibrated spectra are now provided at phase 3 of MUR, together with radial velocity measurements and spectral line equivalent widths for each ARES observed spectrum. More info.

Information for TFRM proposals General No explicit recommendation is given for the maximum observation time for TFRM proposals, although the publicly available observation time is significantly smaller than for the TJO available time. Instrumentation The TFRM operates with a longpass filter above 475 nm and a 4k x 4k front-illuminated CCD camera (FLI PL16803) that provides a 4.4˚ x 4.4˚ field of view and a 3.9"/pixel resolution. Raw images are provided. During this semester the current camera could be replaced by a FLI KL4040BSI (4k x 4k back-illuminated CMOS with similar field of view characteristics of 4.4˚ x 4.4˚ degrees FoV, 3.9"/pixel). Inquiries If you have inquiries regarding TFRM proposals please contact Jorge Núñez jo...@fqa.ub.edu directly.
