Abstract: Results are presented of photometric observations of SN1987A with the Danish 0.5-m telescope at La Silla for the period February 1987-January 1988, including color lines and magnitudes from day 1 to day 300. For the first time, flux calibrations for H-beta passbands were derived. Included are also improved flux calibrations for the uvby passbands.
