The All-sky Survey High Resolution Air shower detector (Ashra) is primarily designed to elucidate transient objects such as Gamma Ray Bursts not only detecting optical lights but also simultaneously TeV, PeV neutrinos, and EeV cosmic rays. Ashra records images in unprecedented arc-minute detail of high-energy cosmic particle interactions in the atmosphere using new wide angle high resolution optics, Image Intensifier and CMOS technology. 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. Full configuration of the Mauna Loa site will be reached by 2006. We will illustrate the summary of the Ashra project and the pilot data with the analysis for optical transient and TeV-ray search.
