论文摘要

目的:我们提供了24个太阳丝的概要图,其中,在1974年至1982年之间,用PIC-DU-MIDI观察结果确定了296个突出的平均磁场向量。这是21周期的上升阶段。方法:磁场是通过解释Hanle效应来确定的,该磁场是通过解释Hanle效应的,该效应是在\ ion clines cliness pliness pliness。先前对临界场极性和突出性手性的结果进行了解决,以解决基本的歧义。由于准确的原因,每个突出的测量值平均。结果:结果是双重的。首先,可以从一条中性线到下一行观察到交替的场方向。其次,沿着太阳南北场发现了一般场对齐,该田地因差异旋转效果而扭曲。与本文相关的在线材料提供了突出及其磁场坐标的数值数据。

Aims : We present 24 synoptic maps of solar filaments, in which the average unambiguous magnetic field vectors of 296 prominences were determined with Pic-du-Midi observations between 1974 and 1982. This was the ascending phase of cycle 21. Methods : The magnetic field was determined by interpreting the Hanle effect, which is observed in the \ion{He}{i} D$_3$ line. Previous results for the prominence field polarity and prominence chirality were applied to solve the fundamental ambiguity. The measurements were averaged in each prominence for accuracy reasons. Results : The result is twofold. First, alternating field directions can be observed from one neutral line to the next. Second, a general field alignment is found along a solar north-south field that is distorted by the differential rotation effect. The numerical data for the prominences and their magnetic field coordinates are provided as online material associated with this paper.
