Period: 2020A (for SST and THEMIS)
Proposal Submission Deadline: 20 January 2020, 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 SST (La Palma) and THEMIS (Tenerife).  This call also includes observing time in the International Time Program (ITP) for 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.

In 2020, 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.

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 in an EU or associated state other than Sweden (for SST), France (for THEMIS) or Spain (for both telescopes).

For ITP time (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.
Information on instrumentation and how to write a proposal can be found at the telescope web pages:
SST
THEMIS
Due to technical works, the next call for GREGOR and VTT will be issued later, probably in February 2020. It is probable that the observing schedules for SST and THEMIS will be set before the deadline of that call.

Proposals can be made for each individual telescope or for a combination of them.  All proposals should be sent via email to east-tac@astro.su.se and must be received by 23:59 UT on January 20, 2020.

SOLARNET is funded by the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 824135.
