Nine photographs taken on 25 Mar., 1986 show that the nucleus of Comet Halley split into 2 widely separated nuclei. The separated projected distance on the plane of the sky is 5000 km. The principal nucleus and the secondary nucleus exhibit their own comas. The prominant jet ejected from the companion curves up to a height of several thousand kilometers and the secondary nucleus must fade out of sight within only a few days. In combination with the results of photoelectric observations it seems that this event of splitting coincides with an outburst. Photographs were digitized, and the image enhancement is described.
