OdM call for proposals 2026A

[Kike Herrero Casas]

Observatori del Montsec (OdM) Call for Proposals | Semester 2026A

Dear observers, The Observatori del Montsec (OdM) opens a Call for Proposals to apply for observation time at the 80-cm diameter Telescopi Joan Oró (TJO) with the LAIA camera and the ARES spectrograph. In addition, in collaboration with the Observatori Fabra of RACAB, the OdM opens a Call for Proposals to apply for observation time at the 50-cm diameter Telescopi Fabra-ROA Montsec (TFRM), which is a modified Baker-Nunn Camera.

Proposals can be submitted until: November 7, 2025 at midnight For observations from January 1 to June 30, 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. LAIA camera LAIA is a 4k x 4k back-illuminated camera that provides a non-vignetted circular 30' FoV and a 0.4"/pixel resolution. LAIA 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. 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 that provides a 4.4˚ x 4.4˚ field of view and a 3.9"/pixel resolution. Raw images are provided. It is expected that this camera will be replaced by a FLI KL4040BSI (back illuminated 4k x 4k CMOS with similar characteristics of 4.4˚ x 4.4˚ degrees FoV, 3.9"/pixel) during the semester. Inquiries If you have inquiries regarding TFRM proposals please contact Jorge Núñez jo...@fqa.ub.edu directly.
