There was a magnetic storm in the photosphere of a sun which was not supposed to have such things.
At first a favorite theory was, that communication had been interrupted by a magnetic storm.
This magnetic storm affected every telegraphic station in the kingdom.
In most cases when such a "magnetic storm" occurs, there is an unusually large or active spot on the Sun.
|magnetic storm |
A disturbance or fluctuation in the Earth's outer magnetosphere, usually caused by streams of charged particles (plasma) given off by solar flares. The entry of large amounts of plasma into the upper atmosphere results in intense auroral displays and other magnetic phenomena in the polar regions of the Earth. See also aurora.
