GREGOR is a 1.5-meter on-axis solar telescope at the Observatorio del Teide in Tenerife. We invite observing proposals for the second season campaign (September to December 2026), with the submission deadline on July 22, 2026. The GREGOR instrumentation and the proposal submission process is described at: https://www.leibniz-kis.de/en/observatories/gregor/observations-with-gregor/

In 2026B we offer HiFI+ and ZIMPOL. GRIS is not avaiblable in 2026B. 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. ZIMPOL: In collaboration with IRSOL, high-precision spectropolarimetric observations with the ZIMPOL polarimeter are offered in service mode.

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 Programme (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/).
