CCI international time program (ITP)
5% of the telescope time is reserved for international access to all solar telescopes on the Canary Islands (GREGOR, VTT, THEMIS). The observing time is assigned by the EAST TAC. For ITP time, applications must include researchers with affiliations in at least two of the following countries: Spain, UK, Germany, France, Italy, and Finland. Contact Dan Kiselman (email@example.com) for more information. Application at https://solarnet-project.eu/Access-Calls
Spanish time (Solar CAT)
See www.iac.es/OOCC/solar-cat/ for more information. According to international agreements, 20% of the observing time is reserved for assignment by the Spanish solar CAT. Presently, there are no restrictions on nationality to apply for GREGOR and VTT time through the solar CAT. Application at www.iac.es/OOCC/solar-cat/.
SOLARNET Access Program
GREGOR days are available for SOLARNET observers in 2023B. The observing time is assigned by the EAST TAC. Application at
Each institute (AIP, MPS, KIS) has guaranteed observing time at GREGOR and VTT. The split is 20%/20%/60% between the AIP, MPS, and KIS of the remaining available observation days.
KIS decided to open their observing time with no restriction on nationality/institute provided that at least one Co-I on the observing proposal is from KIS.
Contact firstname.lastname@example.org for more information.
To apply send the filled-out proposal template found above to kis_tac@~@leibniz-kis.de.
Proposals submitted will be ranked by external reviewers based on their scientific merit. For the time to be allocated by KIS, this will be done in a double-blind manner (i.e. the reviewers will not receive the cover sheet of the proposal - similar to Hubble proposals, physicstoday.scitation.org/do/10.1063/PT.6.3.20190301a/full/), so please avoid mentioning your name in the scientific justification. Subsequently, the proposals are evaluated with further criteria, PhD status, publications of previous observations, no usable data from a previous observation and other hardship cases.

The 1.5-meter GREGOR solar telescope was built by a German consortium under the leadership of the Leibniz-Institute for Solar Physics (KIS) in Freiburg with the Leibniz Institute for Astrophysics Potsdam, the Institute for Astrophysics Göttingen, and the Max Planck Institute for Solar System Research in Göttingen as partners, and with contributions by the Instituto de Astrofísica de Canarias and the Astronomical Institute of the Academy of Sciences of the Czech Republic. The redesign of the GREGOR AO and instrument distribution optics was carried out by KIS whose technical staff is gratefully acknowledged.
