The OPTICON call for Transnational Access in Semester 2022B is OPEN and will close on 28th February 2022

We are pleased to announce that the 2022B call for observing time at optical/IR telescopes supported via OPTICON-Radionet Pilot project is now open. The call will close on 28th February 2022 at 23.59 UT. The Telescopio Nazionale Galileo offers 10 nights from October 1st, 2022 to March 31st, 2023.

Monitoring mode is subjected to severe limitations at TNG. The schedule is dominated by long blocks of full-nights belonging to GTO and Italian Large Programs. Queuing mode is not offered at all. Service time is scheduled on fixed nights so, e.g., seeing requirements do not apply. Objects included in the TNG Protected Target List cannot be requested. Please contact the TNG staff if you have specific time constraints.

A Long-Term program on the optical counterparts of gravitational wave events is already running at TNG. Therefore, proposals on this topic will not be accepted anymore.


The time-sharing agreement between TNG and NOT is no longer in force. Therefore Italian teams can request the Nordic Optical Telescope and Nordic astronomers can request the Telescopio Nazionale Galileo by answering this OPTICON call only.
