Abstract

The All-sky Survey High Resolution Air shower detector (Ashra) is primarily designed to elucidate transient objects such as Gamma Ray Bursts (GRBs) not only detecting optical lights but also simultaneously very high energy γs and γs. A first run of data taking with prototype versions of the optical and the trigger systems took place in 2004-2005, allowing us to evaluate the performance of the systems and to approach an analysis strategy. The advancement of the Ashra optics has been demonstrated by our success of observing the position of GRB041211 from more than 1 hours before the burst for 2 hours continuously. We will present the results of our observations of optical transients with the Ashra prototype.
