List of solar storms
Solar storms are caused by disturbances on the Sun, most often coronal clouds associated with coronal mass ejections (CMEs) produced by solar flares emanating from active sunspot regions, or less often from coronal holes. Most living stars produce disturbances in space weather with the field of heliophysics the science that studies such phenomena; itself primarily an interdisciplinary combination of stellar astronomy and planetary science. In the Solar System, the Sun can produce intense geomagnetic and proton storms capable of causing severe damage to technology including but not limited to large scale power power outages, disruption or blackouts of radio communications (including GPS systems), and temporary or permanent disabling of satellites and other spaceborne technology. Intense solar storms may also be hazardous to high-latitude, high-altitude aviation and to human spaceflight. Geomagnetic storms are the cause of auroras. The most significant known solar storm occurred in September 1859 and is known as the "Carrington event". The damage from the most potent solar storms is capable of threatening the stability of modern human civilization.
