Abstract

The warped heliospheric current sheet for early 1976 is calculated from the observed photospheric magnetic field by a potential field method. Comparisons with measurements of the interplanetary magnetic field polarity for early 1976 obtained at several locations in the heliosphere by Helios 1, Helios 2, Pioneer 11, and at the earth show a rather detailed agreement between the computed current sheet and the observations. It appears that the large-scale structure of the warped heliospheric current sheet is determined by the structure of the photospheric magnetic field and that "ballerina skirt" effects may add small-scale ripples.

摘要

利用位场方法，根据观测到的光球磁场计算出了1976年初扭曲的日球电流片。将其与由“太阳神1号”“太阳神2号”“先驱者11号”在日球层多个位置以及在地球观测到的1976年初行星际磁场极性测量结果进行比较，结果表明计算得到的电流片与观测结果相当吻合。看来，扭曲的日球电流片的大规模结构由光球磁场结构决定，而“芭蕾舞裙”效应可能会增加小规模的波纹。
