古哈萨·库塔说，这种环状气态喷发与太阳磁场强度变化有关。不过，有关日珥形成的具体细节仍是目前较活跃的研究领域。

The looping, gaseous eruptions are linked to changes in the strength of the sun's magnetic field, though the details of how solar prominences form remain an active area of research, Guhathakurta said.

在翻转期间，磁场保持它的双极子外形，保留了古磁学家一直能够追踪南极踪迹的现象。

And during the transition, the field retains its dipole shape, a phenomenon paleomagnetists have traced all the way to the south pole.
