We present preliminary results of the observational campaign on SN 2002er carried out by the European Supernova Collaboration ( ESC ) .
For this supernova the optical coverage from epochs - 11 days to +50 days is excellent , both in imaging and spectroscopy .
The extinction deduced from the photometry is E ( B - V ) = 0.35 , while \Delta m _ { 15 } = 1.31 .
In general SN 2002er behaves like a “ normal ” type Ia supernova , very similar to SN 1996X .
