Trans-National Access Programme Call for Proposals 2021A - GREGOR, SST and VTT


SOLARNET is pleased to announce its seventh call for proposals of its Access Programme for the Solar telescopes GREGOR, SST and THEMIS

Period: 2021A 
Proposal Submission Deadline: 25 January 2021, 23:59 UT
Send proposals to: east-tac@astro.su.se

Proposals are hereby invited under the SOLARNET Trans-National Access Programme for observing time at the solar telescopes GREGOR (Tenerife), SST (La Palma) and THEMIS (Tenerife).  This call also includes observing time in the International Time Program (ITP) for GREGOR and THEMIS.

Proposals will be handled by the EAST TAC, a common European time allocation committee installed by the European Association for Solar Telescopes. Typically, successful proposals in PI visitor mode will be awarded with around 10 observing days. SOLARNET campaigns also get travel grants for two visiting researchers going to the telescope. For GREGOR, this travel may go to Freiburg for remote observations dependent on possible travel restrictions.

In 2021, the SST will provide some of its time in service mode, thus not requiring visits by the investigators. Under SOLARNET, SST will also provide users with reduced data for selected data sets.

This call is for the whole observing season (April-October) for SST and THEMIS and for its first half (April-August) for GREGOR. We expect an additional call later in 2021 for GREGOR where also VTT will be available.

New users of the facilities are encouraged to apply. Certain criteria of eligibility related to the nationalities of the applicants exist and are different for each telescope: 
For SOLARNET time, the PI and at least half the Co-I's must have affiliations other than Germany (for GREGOR), Sweden (for SST), France (for THEMIS) or Spain (for all three telescopes).  Otherwise this call is open to the world, making use of an option in the rules for Access programmes that allow a quota for non-EU and non-associated countries.

For ITP time (GREGOR and THEMIS only), applications must include researchers with affiliations in at least two of the following countries: Spain, UK, Germany, France, Italy, Finland and Belgium.

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

Proposals can be made for each individual telescope or for a combination of them.
