We present optical and near-infrared photometric and spectroscopic observations of SN 2013ej, in galaxy M74, from 1 to 450?d after the explosion. SN 2013ej is a hydrogen-rich supernova, classified as a Type IIL due to its relatively fast decline following the initial peak. It has a relatively high peak luminosity (absolute magnitude MV = ?17.6) but a small 56Ni production of ?0.023 M?. Its photospheric evolution is similar to other Type II SNe, with shallow absorption in the H? profile typical for a Type IIL. During transition to the radioactive decay tail at ?100?d, we find the SN to grow bluer in B ? V colour, in contrast to some other Type II supernovae. At late times, the bolometric light curve declined faster than expected from 56Co de...
