Description

In March 2013, the Nemo Phase II tower has been successfully installed at Capo Passero, Italy, at 3500 m depth. The 8-floor tower hosts 32 10-inch PMTs. Results from the last 3-months background measurements will be presented. In particular, the analyzed rates show stable and low baseline values, compatible with the contribution of 40K light emission, with a small percentage of light bursts due to bioluminescence. All these features are a confirmation of the stability and the good optical nature of the site.
