Query: Photometric investigation of bright type II-P Supernova 2004dj   CCD UBVRI photometry is presented for type II SN 2004dj for about 1200 days,
starting day 2 past discovery. The photometric behaviour is typical for SNe
II-P, although some minor peculiarities are noticed. We compare the photometric
data for the host cluster S96 before and after SN 2004dj outburst and do not
find any significant changes.
