Its properties closely match SN 2003du.

The data span from 1 to 652 days after discovery.

Abstract

We present UBVRI photometry of the supernova 2011fe in M101, obtained in the interval of 1-652 days after its discovery, as well as one spectrum, taken 105 days after the brightness maximum in the B band. We derived parameters of the light curves, constructed the colour curves and a "quasi-bolometric" light curve. The light curves, colour evolution and spectrum of the object indicate that SN 2011fe belongs to the "normal" subset of type Ia supernovae. It is practically identical to a well-studied "normal" SN Ia 2003du.
