We present optical and near-infrared photometry, along with optical spectra,of the Type Ia supernova SN 2000E in the spiral galaxy NGC 6951. It wasdiscovered by the staff of the Teramo Observatory during the monitoring of theSN 1999el. The observations span a time interval of 234 days in the optical and134 days in the near-infrared (starting 16 days and 7 days before maximum Blight, respectively). Optical spectra are available from 6 days before maximumB light to 122 days after it. SN 2000E exhibits a Dm15(B) = 0.94, thus beingclassifiable as a slow-declining Type Ia SN and showing the distinctivefeatures of such a class of objects. Spectroscopically, SN 2000E appears as anormal Type Ia SN, like SN 1990N. We could constrain reddening [E(B-V) ~0.5mag] and distance (mu0 ~32.14 mag) using a number of different methods. Thebolometric luminosity curve of SN 2000E, allows a determination of the Ni56mass amounting to 0.9Msun.Comment: 40 pages, 12 figure
