On February 11, 1982, an unusual cusp-shaped temporal variation in the interplanetary magnetic field was detected by the Pioneer Venus orbiter. While variations of the Helium content of the solar wind were detected on the preceding day, these changes had no obvious relationship to the occurrence of the cusp-shaped temporal variation in the IMF on February 11. In fact the solar wind He content was quite nominal on February 11. The magnetc variations were also quite unlike those previously reported to be magnetic clouds. Moreover, the scale size of the disturbance had to be smaller than 4¿106 km and thus of cometary dimensions rather than of dimensions usually found in solar initiated events. Thus, we see no need to alter our original interpretation that the observations of Pioneer Venus on February 11, 1982 were consistent with the passage of a comet close to Venus. |
