Abstract
We present a novel design of an all-sky 4096×4096 pixels camera devoted to continuous observations of the sky. A prototype camera is running at the BOOTES-1 astronomical station in Huelva (Spain) since December 2002 and a second one is working at the BOOTES-2 station in Málaga (Spain) since July 2004. Scientific applications are the search for simultaneous optical emission associated to gamma-ray bursts, study of meteor showers, and determination of possible areas for meteorite recovery from the reconstruction of fireball trajectories. This last application requires that at least two such devices for simultaneously recording the sky at distance of the order of ~ 100 km. Fifteen GRB error boxes (13 for long/soft events and 2 for short/hard GRBs) have been imaged simultaneously to the gamma-ray emission, but no optical emission has been detected. Bright fireballs have been also recorded, allowing the determination of trajectories, as in the case of the fireball of 30 July 2005. This device is a very promising instrument for continuous recording of the night sky with moderate angular resolution and limiting magnitude (up to R ~ 10).
