摘要：The "Pi of the Sky" experiment is designed for continuous observation of a large part of the sky
in search for optical flashes associated with gamma ray bursts (GRBs) and other short optical
transients. It is also a sophisticated instrument looking for novae and supernovae stars. The
apparatus consists of two arrays, 16 CCD cameras each, working in coincidence mode. The
whole system continuously observes 2 steradians of the sky with a time resolution of 10 seconds.
The whole system is currently in an advanced stage of construction. Required hardware and
software tests were performed with a prototype. It is located in Las Campanas Observatory in
Chile and consists of two cameras working in coincidence. The detector allows us to search for
optical counterparts of GRBs and study other kinds of short timescale astrophysical phenomena.
The "Pi of the Sky" analysis system is a very efficient tool. The automatic trigger detected bright
flares (for example CN Leo, GJ 3331A / GJ 3332), cataclysmic variables (for example dwarf nova
1RXS J023238.8-371812), some spectacular meteor explosions and others interesting events.
