The CAT Time Allocation Committee has issued a call for proposals for CAT time for observations in Semester 2016B (1st Jul 2016 → 28th Feb 2017).
The deadline for submission of proposals is 17:00 (Canarian local time) on Monday, 4th April 2016.

Full details of the the eligibility requirements and application procedure may be found on the CAT website. Briefly, CAT accepts applications for which the principal investigator (PI) is affiliatied to a Spanish Institution. PATT accepts proposals from PIs based in the UK. Some non-UK and non-Spanish PIs are eligible to apply through the OPTICON Trans-national Access programme, or through the International Scientific Committee (CCI). Non-UK PIs who are not eligible for CAT, OPTICON or CCI time may apply through PATT. Please note that each TAC has its own, different application forms.

In addition to the once-per-semester call for proposals, CAT reserves a small proportion of their time allocation to provide rapid response to unforeseen targets of opportunity. You may apply for Reactive Time at any time throughout the year as described here.

Full details of the 16B Call for Proposals are available from the CAT website.
