V Band Photometry of the SN 2003gf Supernova Utilizing the 2MASS Ca

We obtained several images of SN2003gf at the Marangani Observatory (Peru) on the night 3–4 July 2003 from which we have estimated its brightness in the V band, as 15.10±0.09 mag. This was obtained after a proper calibration of the starfield, considering the photometric data of the infrared bands of the 2MASS catalog. The precision achieved shows a reasonable agreement with measurements by other observers.
