Pi Of The Sky

(survey aimed at finding gamma-ray-burst visual counterparts)

Pi Of The Sky is an Astronomical Survey aimed specifically at discovering Optical Transients associated with Gamma-Ray Bursts. It naturally also records other types of transients of interest.

It is performed by a robotic-telescope setup designed for the purpose. The aim is to be watching a significant portion of the night sky over every suitable night, and thus catch any gamma-ray bursts that happen to occur then and there. A pilot with two such telescopes, with CCD cameras, operated from 2004 to 2009, with a four-camera system going into service in Spain in 2010, and sixteen cameras in 2013, able to view an 80°×80° Field of View.
