SOLARNET is pleased to announce its 9th call for proposals of its Access Programme for the Solar telescope GREGOR

Period: 2022B Proposal Submission Deadline: 20 May 2022, 10:00 UT
Send proposals to:

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).

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 will be awarded with about 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 mode observations.

This call is for the second half of the observing season (13 July – 2 December). Starting from October observations do not take place on weekends.

New users of the facilities are encouraged to apply. Certain criteria of eligibility related to the nationalities of the applicants exist:

For SOLARNET time, the PI and at least half the Co-I’s must have affiliations other than Germany or Spain (for GREGOR).  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 CCI/ITP time, 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 the telescope and the instrumentation can be found at the telescope web page:

A complete proposal consists of a SOLARNET or CCI/ITP form plus a form specific to the telescope.
