We present optical ( UBVRI ) and near-infrared ( JHK ) photometry , along with optical spectra , of the Type Ia supernova SN 2000E in the spiral galaxy NGC 6951 .
It was discovered by the staff of the Teramo Observatory during the monitoring of the SN 1999el .
The observations span a time interval of 234 days in the optical and 134 days in the near-infrared ( starting \sim 16 days and \sim 7 days before maximum B light , respectively ) .
Optical spectra are available from 6 days before maximum B light to 122 days after it .
The photometric behavior of SN 2000E is remarkably similar to that of SN 1991T and SN 1992bc : it exhibits a \Delta m _ { 15 } ( B ) = 0.94 , thus being classifiable as a slow-declining Type Ia SN and showing the distinctive features of such a class of objects both in the visible and in the near-infrared .
Spectroscopically , SN 2000E appears as a “ normal ” Type Ia supernova , like SN 1990N .
We could constrain reddening [ E ( B - V ) \sim 0.5 mag ] and distance ( \mu _ { 0 } \sim 32.14 mag ) using a number of different methods .
The bolometric luminosity curve of SN 2000E , which displays a bump at the epoch of the secondary near-infrared peak , allows a determination of the ^ { 56 } Ni mass , amounting to 0.9 M _ { \sun } .
