About 200 CCD images of the comet C/1996 B2 - HYAKUTAKE were obtained and reduced, using four approaches by PPM stars and one by a GSC star, on March 20, 24, 25 and April 1-st, 1996, in Bucharest. Also, three photographical plates were reduced using PPM stars. The O-C analysis of the astrometric data allowed the testing of the accuracy of both the observational technique and the reduction method. The variation of the orientation of the comet's tail was also computed.
