Observing Season and applications for observing time

General Info

GREGOR Observing plan 2018 (updated May 7, 2018):



Due to changes in setup and instrumentation, the observing season 2018 is split into two halves: April 15 - end of July, 2018 and from September 1 - December 15, 2018. 


GREGOR call for proposals: 2018B (Sep 1 - Dec 15)

Deadline:  June 4, 2018, 23 UT.


We invite observing proposals for the second season of 2018. Instrumentation available for the second season is:
- GRIS: slit spectropolarimetry at wavelengths 1.0-1.3 or 1.5-1.8 microns
- NEW: GRIS IFU (image slicer) at wavelengths 1.0-1.3 or 1.5-1.8 microns. This instrument is being offered for the first time and can record spatial and spectral information simultaneously in a FOV of 6”x3”. You can choose either the IFU or the slit in GRIS, but only one of them per campaign. If proposals are ranked equally, IFU campaigns will be preferred. More technical details can be found here.

- Fast context imaging. Wavelengths below 500 nm are guaranteed with the present setup. A new pentaprism allowing wavelengths up to 900 nm has been ordered and is expected to be available, which means that any wavelength below 900 nm (if not using GFPI) could be used for fast imaging if a suitable filter is available or provided by the observers.

- GFPI: This instrument is available without any support from KIS. Please check the "Scientific instruments" page for the current capabilities and restrictions.

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 in 2018B:
- KIS: 43 days. 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: 16 days. Eligibility: No restriction on institute/nationality.
The remaining time is reserved for partners.

The proposal form for KIS 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) or H. Socas Navarro (Spanish time; hsocas@iac.es).




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.
