RARE PROCESSES AND ASTROPHYSICS NESTOR EXPERIMENT IN 2003

NESTOR is a submarine high-energy muon and neutrino telescope, now under construction for deployment in the Mediterranean close to Greek shores. The first floor of the NESTOR with 12 optical modules had been deployed successfully in March 2003 together with electronics system. All systems and the associated environmental monitoring units are operating properly and data are being recorded. The status of the NESTOR project is presented. We outline briefly the construction of deepwater neutrino telescope, properties of the NESTOR site, infrastructure of the project, the deployment of the first floor and its current operation. First data are presented and plans for next steps are summarized.
