  We present multicolor light curves of SN 1998bw which appeared in ESO184-G82
in close temporal and spacial association with GRB 980425. They are based on
observations done at Cerro Tololo Inter-American Observatory and data from the
literature. The CTIO photometry reaches ~86 days after the GRB in $U$ and ~160
days after the GRB in BV(RI)_C. The observations in U extend by about 30 days
the previously known coverage, and determine the slope of the early exponential
tail.
  We calibrate a large set of local standards in common with those of previous
studies and use them to transform published observations of the SN to our
realization of the standard photometric system. We show that the photometry
from different sources merges smoothly and provide a unified set of 300
observations of the SN in five bands. Using the extensive set of spectra in
public domain we compute extinction and K corrections, and build
quasi-bolometric unreddened rest frame light curves. We provide low degree
piecewise spline fits to these light curves with daily sampling. They reach ~86
rest frame days after the GRB with U band coverage, and ~498 rest frame days
after the GRB without U.
