Observing Season and applications for observing time

Applying for observing time 2018:

Due to expected changes in setup and instrumentation, the observing season 2018 will be split into two halves: April 15 - August 15, 2018 and from August 15 - December 15, 2018.


The call for proposals 2018A is open:

We invite proposals for observing campaigns at GREGOR for the first season of 2018, with a submission deadline of January 15, 2018, 23 UT. Another call for the second season may be expected in spring 2018.


Instrumentation available for the first season is:
- GRIS: slit spectropolarimetry at wavelengths 1083 nm or 1.5 microns
- GFPI: imaging spectropolarimetry from 530-860 nm. For wavelengths below 650 nm co-observations with GRIS are possible. For 650-850 nm, GRIS co-observations cannot be guaranteed yet.
- Fast context imaging. Wavelengths below 500 nm are guaranteed, wavelengths up to 900 nm may be possible.

Proposers reapplying for observing time are reminded that their proposal will be evaluated based on previous publications or their clear analysis in the proposal why former data were not sufficient and will automatically be rejected in case of not having submitted an observing report.

There are different quotas for observing time:
- KIS: 45% of the total time. Eligibility: Any researcher with no restriction on institute/nationality can apply for observing time if at least one collaborator from KIS is included in the proposal.
- Spanish time: 20% of the total time. Eligibility: No restriction on institute/nationality.
- CCI time: 5% of the total time. Eligibility: Any researcher can apply, except for the lead institute of a telescope (i.e. KIS cannot apply as PI at GREGOR).
The remaining time is reserved for partners.

The proposal form for KIS/CCI time can be downloaded here and shall be submitted to tac@leibniz-kis.de:

Information on proposal submission for Spanish time, which is handled separately by a different TAC with different deadlines can be found here:

For questions, please contact L. Kleint (KIS time; lucia.kleint@leibniz-kis.de), H. Socas Navarro (Spanish time; hsocas@iac.es), or R. Schlichenmaier (CCI time; schliche@leibniz-kis.de).



General Info


GREGOR Observing plan 2017 (updated October 2017):



Options for telescope access
CCI international time program (ITP):

5% of the telescope time are reserved for international access to all solar telescopes on the Canary Islands (SST, DOT, GREGOR, VTT, THEMIS). The observing time is assigned by the EAST TAC. Anybody apart from the operator of each telescope can apply for observing time (e.g. KIS cannot apply for GREGOR or VTT time). Contact Rolf Schlichenmaier at KIS for more information.

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.

German time (split 20%/20%/60% between the AIPMPS, and KIS, leading to effective observing times of 15%/15%/45% of the total available time)

Each institute has guaranteed observing time at GREGOR and VTT. 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 tac@leibniz-kis.de for more information.
