5% International Time Programme is open, deadline 29-02-2020

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

The current call (for the periods starting with semester 2020B=AOT42) is open until February 29, 2020. The call can be downloaded here.

Observing time is available to organisations of the Signatory Countries (Spain, Germany, UK, Italy, France, Belgium and Finland), their collaborating institutions of any country and to all Spanish Institutions, with permission from the IAC.

All proposers must contact the corresponding telescope operator for an initial technical appraisal on the feasibility of their proposed observations. Requests are evaluated jointly by the time allocation committees of each telescope operator. The CCI informs the PIs of the awarded proposals in June.

For the TNG, there are 15 nights per year, but no more than eight nights can be requested in one semester. GIANO-B instrument could have a limited time availability in semester 2020B due to maintenance.

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.
