Scientific paper

Optical UBVRI photometry of the type Ia supernova (SN Ia) SN 2002hu covering the period from -2 to +73d since B maximum is presented. The supernova reached at maximum brightness in B on JD2452591.78 +/- 0.5 with an apparent magnitude of 16.83 +/- 0.02mag and a relatively blue colour (B-V) =-0.08 +/- 0.04mag. The luminosity decline rate of Δm15(B) = 1.00 +/- 0.05 indicates an absolute B magnitude at maximum of MmaxB=-19.38 +/- 0.3. The estimated absolute B magnitude, together with the photometric evolution, indicate SN 2002hu was slightly overluminous compared to the average SNe Ia. The distance modulus to the parent galaxy is estimated to be μ= 36.04 +/- 0.20.
