Large-scale propagation properties of an interplanetary disturbance in association with a 'halo' coronal mass ejection on 27 November 1979
Abstract
Propagation properties of an interplanetary disturbance in association with a halo coronal mass ejection (CME), which was observed with the Solwind coronagraph from 08:22 to 09:58 UT on November 27, 1979, are examined utilizing IPS and spacecraft observations. Detailed model-fitting showed that a dip of the propagation speed of the disturbance was situated in the radial direction of the heliospheric current sheet. Quick deceleration of the disturbance along the current sheet is suggested.
