Trans-National Access Programme Call for proposals

SOLARNET is pleased to announce its second call for proposals of its Access Programme.

Solar telescopes GREGOR and VTT

Period 2019B (Aug 12 – Nov 30)
Proposal Submission Deadline: 2 June 2019, 23 UT
Send proposals to east-tac@astro.su.se

Proposals are hereby invited for observing time at the solar telescopes GREGOR and VTT at the Observatorio del Teide in Tenerife. This call is for observing time awarded under the SOLARNET Trans-National Access Programme and a small amount of observing time in the International Time Program (ITP). All proposals will be treated as being for both.

GREGOR Solar Telescope

GREGOR is a 1.5 meter on-axis solar telescope operated in PI visitor mode offering the following instrumentation options.

GRIS spectropolarimetry at wavelengths 1.0–1.3 or 1.5–1.8 microns. Operated in either IFU mode (image slicer) or slit mode. The GRIS IFU campaigns will be scheduled in Aug-Sep and the GRIS slit spectrograph campaigns in Oct-Nov.

GFPI imaging spectroscopy (no polarimetry) at wavelengths below 860 nm. Available only in collaboration with Leibniz Institute for Astrophysics Potsdam (AIP), please contact them before writing a proposal. Please see our website for the current capabilities and restrictions.

Both GRIS and GFPI observations can be complemented with fast context imaging in any wavelength below 900 nm (below 480 nm for GFPI) if a suitable filter is available or provided by the observers.

VTT Solar Telescope

VTT is a coelostat with a 70 cm main mirror, operated in PI visitor mode, with two instrumentation options available.
The chromospheric or photospheric grating for spectroscopy in up to 3 spectral regions simultaneously.
Instrument setups provided by the user.

Proposal Submission

Time is typically awarded in blocks that are of the order of 10 days long. We expect that there will be about 20 d available on GREGOR and about 10 d on VTT.

Proposals requesting simultaneous use of GREGOR and VTT (co-observations) will be treated as one proposal to be accepted or rejected in its entirety. For the possibility of using only one telescope, please submit a separate proposal for that telescope.

For SOLARNET time, the PI and the majority of the users must work at institutions which are not located in Germany or Spain. Travel and lodging grants are available for up to two observers.

Proposals will be handled by the EAST TAC, a common European time allocation committee installed by the European Association for Solar Telescopes.

The proposal form and additional information on the instrumentation can be found here:

www.leibniz-kis.de/en/observatories/vtt/observing-with-vtt/
and on the adjacent “Scientific instruments” pages.

For technical questions, please contact L. Kleint.

Data acquired in the SOLARNET Access Programme will become public one year after being delivered to the PI.
