Results of [FORMULA] CCD photometry of the bright supernova SN 1999by in the flocculent galaxy NGC 2841 are presented. The Multicolor Light-Curve Shape (MLCS) method is applied to fit the observed V lightcurve around its maximum-light period. The reddening and the luminosity correction parameters were estimated.
