"We have imaged the field of the GRB 030329 (GCN 1997) in four optical
colours with the 2.2 m (+BUSCA) telescope at the Observatorio de Calar
Alto on 20.9148-20.9670 UT May 2003. Aperture photometry of the
counterpart yielded Ic = 20.92 +/- 0.07. The zero point is based on the
star located at R.A.(J2000) = 10:44:42, Dec(J2000) = +21:32:31.6 with
I = 15.432 (GCN 2082). Further observations are planned."
