Abstract
A generalized Finson-Probstein formalism was used to analyse the streamer patterns in the dust tail of Comet Halley as observed between 22 February and 11 March, 1986. A periodic appearance of a pattern of double streamers was found in the dust tail, indicating a time interval in the emission of this structures of about 6.5 days, if interpreted as synchrones. The time interval between the emission of the two components of each double streamer is about 2.5 days. The results are discussed with respect to the rotation of Halley's nucleus.
