Since stars apparently identical to the Sun can produce superflares it is natural to ask if the Sun itself can do so, and to try to find evidence that it has done in the past.Large flares are invariably accompanied by energetic particles, and these particles produce effects if they reach the earth.The Carrington event of 1859, the largest flare of which we have direct observation, produced global auroral displays extending close to the equator.
