Within the SOLARNET transnational ACCESS program ( ) we invite proposals for observing campaigns at GREGOR in 2016. GREGOR is a 1.5 meter on-axis solar telescope at the Observatorio del Teide in Tenerife, and is presently equipped with an infrared spectropolarimeter (GRIS), a dual Fabry-Perot spectrometer (GFPI), and an additional imaging channel.


In 2016, GREGOR observing time is offered through the ACCESS program of SOLARNET. Please consult the EAST TAC web page to view the call for proposals, or contact

We will allocate some 34 observing days at GREGOR in 2016 within the SOLARNET ACCESS program. For these campaigns one of our scientists will serve as an observing assistant. We offer GRIS (with a spectral range of 0.4 nm in the 1 and 1.5 micron windows, scanning a field of view of approx. 60'' by 60''), its slit jaw imaging system, and/or the GFPI.

The GFPI is a filter spectrometer spectroscopic mode (spectral resolution of some 250 000, field of view 50'' by 38'') for the measurement of material flows in different layers of the solar atmosphere using selected spectral lines in the range 530 nm < lambda < 650 nm. The range can be extended up to 860 nm if no simultaneous observations with GRIS are requested. (For more information please contact cdenker[at]

The blue channel of the GFPI with filters for Ca H, G-band and continuum at 450 nm can be used for imaging.

Proposals should be sent via email to and must be received by January 20, 2016. For questions on GREGOR, its instrumentation, and on the proposal, please contact Rolf Schlichenmaier ( as soon as possible. The proposals will be evaluated based on scientific merit. Eligibility: The proposal PI and more than half of the Co-Is must be affiliated with an institute in EU or associated EU countries, but non-Spanish and non-German.

SOLARNET is a European Integrated Initiative funded through FP7, which brings together and integrates the major European research infrastructures in the field of high-resolution solar physics ( ). This includes the European Solar telescopes SST, THEMIS, GREGOR & VTT in the Canary Islands, as well as European instruments IBIS and ROSA installed at DST/NSO. SOLARNET support includes travel grants for observing campaigns.
