January 1938 geomagnetic storm

1938 solar storm

The 25–26 January 1938 geomagnetic storm was a massive solar storm which occurred 16–26 January with peak activity on 22, 25, and 26 January and was part of the 17th solar cycle. As the electrification of Europe and North America was still in its infancy, the light storm could be seen brilliantly. The intensely bright arches of crimson light with shifting spectrum of green, blue-white, and red radiated from a brilliant auroral crown near the zenith instead of appearing as usual in parallel lines. This aurora is believed by many people, especially those of the Catholic faith, to be related to the Fátima Prophecies.
