1986

Abstract

Post-perihelical photometric observations of comet Halley were performed on 25 nights at the 50 cm reflector of UFRGS by the technique of strip photometry. A slit of dimensions 8arcmin×8arcsec scanned the comet image at a speed of 1arcsec.345 cos delta sec-1, in east-west direction or inversely.
