The Carrington Event was the most intense geomagnetic storm in recorded history, peaking on 1–2 September 1859 during solar cycle 10. It created strong auroral displays that were reported globally and
Sunspots of 1 September 1859, as sketched by Richard Carrington. A and B mark the initial positions of an intensely bright event, which moved over the course of five minutes to C and D before disappearing.
Image of the July 2012 solar storm, which generated CMEs of comparable strength to the one of 1859. The small bright circle in the light baffle demonstrates the size of the Sun.

A coronal mass ejection is a significant ejection of plasma mass from the Sun's corona into the heliosphere. CMEs are often associated with solar flares and other forms of solar activity, but a broadl

…displays that were reported globally and caused sparking and even fires in telegraph stations. The geomagnetic storm was most likely the result of a coronal mass ejection (CME) from the Sun colliding with Earth's magnetosphere. The geomagnetic storm was associated with a very bright solar flare on 1 September 1859. It…
When observed in white-light coronagraph imagery, CMEs sometimes resemble a light bulb, possessing a bright bulb-like outer shell surrounding a dark void and compact inner structure.
