The Science and Technology Facilities Council and the Institute of Astrophysics of the Canary Islands (IAC) invite applications for their international time programme. This enables researchers to access certain telescopes installed at the Roque de los Muchachos observatory, which includes the Liverpool Telescope and the Teide Observatory. The aim of this programme is to encourage international scientific projects that cannot be easily accommodated within other time allocation schemes and that foster collaboration between the different user institutions at the observatories. The following telescopes are available: •TNG (3.58m); •NOT (2.56m); •INT (2.54m); •MERCATOR (1.2m); •GTC (10m); •LT (2m); •STELLA (2x1.2m). 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 that would be unlikely to obtain the necessary large amount of observing time due to the difficulty to coordinate several telescopes, are particularly encouraged. Projects should include international 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, namely Belgium, Finland, France, Italy, Spain and the UK. Astronomers from scientific institutions from any other country in the world can be included. Up to five per cent of the observing time, evenly spread throughout the year and the lunar cycle, is available. Proposals can request up to 15 nights per year for TNG, NOT, INT and MERCATOR, and 80 hours for GTC, LT and STELLA. Proposals can cover a period of up to two consecutive years.
