Paper Abstract

Pi of the Sky is a system of wide field-of-view robotic telescopes, which search for short timescale astrophysic phenomena, especially for prompt optical GRB emission. The system was designed for autonomous operatio , monitoring a large fraction of the sky with 12m-13m range and time resolution of the order of 1 - 10 second , and automatic flash recognition in real time. System design and observation stratedy was successfully tested with a prototype detector operational in 2004- 2009 at Las Campanas Observatory, Chile, and moved to San Pedro de Atacama Observatory in March 2011. In October 2010 the first unit of the final Pi of the Sky detector system, with 4 CCD cameras, was successfully installed in the INTA El Arenosillo Test Centre in Spain. Three more units (12 CCD cameras) are being prepared for installation on a new platform in INTA, aiming at a total coverage of about 6400 square degrees. Observation strategy and background conditions are different than those in Chile. Therefore additional selection algorithm are needed to improve rejection of false flash candidates selected by the on-line selection algrithm.
