5% International Time Programme is open, deadline 28-02-2021

ITP 2021

The International Scientific Committee (CCI) of the Roque de los Muchachos (ORM, La Palma) and Teide (OT, Tenerife) observatories invites applications for the International Time Programme (ITP) on the telescopes installed at these Observatories.

The current call (for the periods starting with semester 2021B=AOT44) is open until February 28, 2021. The call can be downloaded here.

Proposals should be international in their range of participants and are expected to involve astronomers from at least three of the seven European countries that are signatories to the Agreements for Cooperation in Astrophysics (Spain, Germany, UK, Italy, France, Belgium, and Finland). Moreover, astronomers from scientific institutions from any other country in the world can be included.

The PIs needs to contact the corresponding telescope staff ito discuss available instruments and for an initial technical appraisal on the feasibility of their proposed observations. For the TNG, there are 15 nights per year, but no more than eight nights can be requested in one semester.

The observing programmes should concentrate on a single astronomical investigation. Proposals that would benefit from the use of more than one facility, and in particular those which would be unlikely to obtain the necessary large amount of observing time through the usual time allocation panels because of the difficulty to coordinate several telescopes, are especially encouraged. Hence, a typical ITP program is a large or a small international program that involves a complementary use of different telescope facilities, with a clear case why the total is more than the sum of the parts.
