Deadline: 04/04/2018

Up to 16 nights during the second semester of 2018 (1 July – 31 December) are available.

The application deadline is 4 April 2017, 23:59 CEST (the same deadline as for the open time).

The proposals have to be presented through the official CAHA website (see below).


  • The Principal Investigator (PI) and at least one half of the research team should be affiliated to a Spanish Institution.
  • This call for proposals is meant to help the projects requiring a moderate or large number of observing nights. Proposals will be evaluated by a time allocation committee on the basis of scientific quality and feasibility of the project with the available instrumentation.
  • Proposals of on-going projects should be submitted following the procedure mentioned above, including those results obtained so far in the “Long Term Project” section, and an estimation of nights that will be required in the next semesters. Any other information, which might help the evaluation can be attached to the proposal.
