The GREGOR instrumentation and the proposal submission process is described at: https://www.leibniz-kis.de/en/observatories/gregor/observations-with-gregor/
In 2026A the GRIS spectropolarimeter can be used with up to three simultaneous arms in Ca II IR 854.2 nm and He I 1083.0 nm and 770 nm in the slit scanner mode. As before, HiFI+ offers near-diffraction limited imaging with 50 to 100 frames per seconds in six spectral windows: Ca II H, G-band, blue continuum, broad- and narrow-band H-alpha, and TiO. The conventional AO system was recently upgraded with a faster Tip/Tilt mirror leading to an improved performance. In addition to the conventional AO, GREGOR offers a new off-limb AO mode for off-limb prominence observations with wavefront sensing in Halpha.
All observations can be executed either in person on-site or in remote mode.
Application can be submitted via the KIS time contingent allocated by the KIS Time Allocation Committee or via the International Time Program (ITP/CCI: https://www.iac.es/en/observatorios-de-canarias/international-scientific-committee) that is allocated by the EAST TAC (email to [email protected]) or via the Spanish TAC (http://research.iac.es/OOCC/solar-cat/).
