During the Halley Monitoring Program at La Silla from Feb. 17 to Apr. 17, 1986 a striking phenomenon in the coma of comet Halley was observed. In the light of the neutral CN-radical a continuous formation and expansion of gas-shells could be observed. These shells can be followed for several days until reaching a diameter of 106km. The gas-expansion velocity decreases with increasing heliocentric distance from 1 km/s in early March to 0.8 km/s in April. Basically, the shells are spherical, although often modified by an elliptic or spiraloid distortion. During expansion, their centres move in the direction of the comet's tail. The initial starting points are more or less equally spaced in time. This indicates a release of gas from isolated areas on the nucleus and allows an independent determination of the rotation-period.
