We present our photometric observations of the 15 supernovae (SN) discovered in the period 1997-1999; of these, six are type Ia SN, two are peculiar type Ia SN, three are type Ib/c SN, and four are type II SN. For 11 SN, we constructed reliable light curves and determined their maximum brightnesses and absolute magnitudes at maximum. Based on the shapes of the light curves, we improved the classification for three type II SN. We show that the two peculiar type Ia SN (similar to SN 1991T) studied, SN 1998es and SN 1999aa, have enhanced and normal luminosities at maximum, respectively.
