as geomagnetic
storms can disturb Earth's
magnetic field, interfering with electric power grids, radio communication, GPS systems, satellite operations, oil and gas drilling and air travel.

as auroral sightings in Meigetsuki («The Record of the Clear Moon,» ca 1180 - 1241) by Fujiwara no Teika of Japan, and in Song Shi («History of Song,» commissioned 1343) from China, have given researchers the ability to reconstruct a chronology of past astronomical events.
