GREGOR/VTT – Call for Observing Proposals 2019A (Apr 28 – Aug 1)

December 15, 2018, from Richard Morton

GREGOR is a 1.5 meter on-axis solar telescope at the Observatorio del Teide in Tenerife operated in PI mode. VTT is a coelostat with a 70 cm main mirror, also operated in PI mode. We invite proposals for observing campaigns at GREGOR and/or VTT in 2019, with a submission deadline of January 18, 2019, 23 UT. Both telescopes will operate with 2 observing seasons in 2019 and the available instrumentation differs in both seasons. This call is for the first season, another call may be expected in May.

Instrumentation available for the first season is:


    • GRIS IFU (image slicer) at wavelengths 1.0–1.3 or 1.5–1.8 microns. This instrument can record spatial and spectral information simultaneously in a FOV of 6”x3”. Simultaneous H-alpha and continuum slitjaw images are available.
    • 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 for the current capabilities and restrictions.
  • VTT:

    • The chromospheric grating for spectroscopy in up to 3 spectral regions simultaneously
    • Own instrument setups

There are different quotas for observing time in 2019A:

  • 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. Eligibility: No restriction on institute/nationality.
  • CCI time: 8 days. Application via EAST TAC. Eligibility: Anybody apart from the operators of the telescope.
  • SOLARNET (see separate call, send proposals to Deadline 20 January): 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.

The remaining time is reserved for partners.

The proposal form for KIS time and more information on the instrumentation can be found here:

and on the “Scientific instruments” page. Proposal submission for SOLARNET and Spanish time is announced in separate calls.
