On the 13th of May 2002, supernova 2002cv was discovered using anear-infrared camera working at the AZT-24 1.1m telescope at Campo Imperatore(AQ-Italy). After the infrared detection a simultaneous photometric follow-upwas started at optical wavelengths. The preliminary results confirm a heavilyobscured object with a V-K color not lower than 6 magnitudes, making SN 2002cvthe most reddened supernova ever observed. This finding, along with the recentdiscovery of another obscured supernova, suggests a critical revision of therates known to date. The estimate of the visual extinction and the light curvesare provided here. These latter indicate that our SN 2002cv observations arethe earliest available for a type-Ia supernova at IR wavelengths.Comment: 4 page
