On July 23, in the year 2012, The Solar storm of 2012 was an unusually large coronal mass ejection that was emitted by the Sun which barely missed the Earth by nine days. If it hit, it would have caused up to US$2.6 trillion in damages to electrical equipment worldwide. This event is recorded as a Historical Events event in the history of July 23, one of 434 recorded events on this date across all of history.

On July 23, 2012 at 02:08 UTC, a solar storm involving an unusually large and strong coronal mass ejection occurred. It missed Earth by a margin of roughly nine days, as the Sun's equator rotates around its own axis once over a period of about 27 days. The region that produced the outburst was thus not pointed directly towards Earth at that time. The strength of the eruption has been predicted to be comparable to the 1859 Carrington Event that caused damage to electrical equipment worldwide, which at that time consisted mostly of telegraph systems. Had it hit Earth, it is believed that the storm would have caused widespread technological damage.
