THEMIS 2023 observing campaign will take place approximately from Apr 15th to Oct 30th 2023 for about 100 days. Incoming information will be posted here and on our site portal as soon as it becomes available. We encourage everyone to apply.

Use of the THEMIS telescope is granted by rights to the French and Spanish communities, but also to the European and international community under the SOLARNET(1) and CCI-ITP time allocation procedures. The International Scientific Committee (CCI) of the Instituto de Astrofisica de Canarias (IAC), overseeing the Canary Islands telescopes, awards observing time through its International Time Program (ITP). SOLARNET awards observing time under its trans-national ACCESS program. Proposals for ITP and SOLARNET time are both allocated by the EAST-TAC, a joint European time allocation committee of the European Association for Solar Telescopes (EAST), and sharing the same deadlines.

• Applicants to “French time”: 75% of the campaign,about 75 days. French users must take care of their travel and subsistence expenses.
• As a EU or associated state member, you can apply to the same french time within the SOLARNET/Trans National Access program (see for your eligibility and others details on the same page). The SOLARNET/Access program offers travel and subsistence (T&S) grants for the observing run.
• Applicants to “Spanish time”: 20% of the campaign, 20 days for 2023.
