Observing Season and applications for observing time

General Info

Due to changes in setup and instrumentation, the observing season 2019 will be split into two halves: April - beginning of August and from mid August - end of November, 2019.

Call for Proposals: GREGOR/VTT – 2019B (Aug 12 – Nov 30)

Submission Deadline June 2, 23 UT.

We invite proposals for observing campaigns at GREGOR and/or VTT in 2019, with a submission deadline of June 2, 2019, 23 UT. Both telescopes operate with 2 observing seasons and the available instrumentation differs in both seasons. This call is for the second season. In case of oversubscription, the proposals will be ranked by external referees based on scientific merit. For the German time, this will be done in double-blind mode (i.e. the referees will not obtain the cover page of the proposal - similarly to Hubble proposals, https://physicstoday.scitation.org/do/10.1063/PT.6.3.20190301a/full/), therefore please avoid mentioning your name in the scientific justification.

 

The proposal form can be downloaded here and shall be submitted to tac@leibniz-kis.de or the respective TACs:

Instrumentation available for the second season is:
GREGOR:
•    GRIS spectropolarimetry with the IFU (image slicer) or regular slit at wavelengths 1.0–1.3 or 1.5–1.8 microns. The IFU can record spatial and spectral information simultaneously in a FOV of 6”x3”. Simultaneous H-alpha and continuum slitjaw images are available. The GRIS IFU campaigns will take place from ~Aug-Sep and the GRIS slit specrograph campaigns from Oct-Nov.
•    Fast context imaging in any wavelength below 900 nm (below 480 nm if using GFPI) if a suitable filter is available or provided by the observers.
•    Imaging spectroscopy (no polarimetry) with GFPI at wavelengths below 860 nm. This instrument is available only in collaboration with AIP and please contact them before proposal submission.
Please see our website (http://www.leibniz-kis.de/de/observatorien/gregor/scientific-instruments/) for the current capabilities and restrictions.

VTT:

•    The chromospheric or photospheric grating for spectroscopy in up to 3 spectral regions simultaneously. The VTT grating will be exchanged in Sep/Oct if requested by the submitted proposals.
•    Own instrument setup

 

There are different quotas for observing time in 2019B:
- KIS: 24 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. Application via Spanish CAT. Eligibility: No restriction on institute/nationality.
- CCI time: 4 days. Application via EAST TAC. Eligibility: Anybody apart from the operators of the telescope.
- SOLARNET (see separate call, send proposals to east-tac@astro.su.se): 20 days. Eligibility: The PI and the majority of the users must work at institutions which are outside the country(ies), which operate the telescope (Germany, Spain). Travel and lodging grants are available for up to 2 people.


For questions, please contact L. Kleint (KIS and GREGOR/VTT SOLARNET time; lucia.kleint@leibniz-kis.de) or E. Khomenko (Spanish time; khomenko@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 (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 Dan Kiselman or Lucia Kleint 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.

SOLARNET time

A total of 40 days (GREGOR) or 20 days (VTT) are available for SOLARNET observers in 2019. The observing time is assigned by the EAST TAC.

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.
