The solar storm of 2012 was a solar storm involving an unusually large and strong coronal mass ejection that occurred on July 23, 2012. 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 25 days.
Comparable in size to the May 2024 storms. [46] Oct 1903 Solar storm of Oct-Nov 1903 An extreme storm, estimated at Dst −531 nT arose from a fast CME (mean ≈1500 km/s), occurred during the ascending phase of the minimum of the relatively weak solar cycle 14, which is the most significant storm on record in a solar minimum period. Aurora was ...
On July 23, 2012, STEREO-A was in the path of the Carrington class CME of the solar storm of 2012. [15] This CME, it is estimated, if it had collided with Earth's magnetosphere, would have caused a geomagnetic storm of similar strength to the Carrington Event, the most intense geomagnetic storm in recorded history.

In 2012, a solar flare far larger than either the May storm or the one now in progress — described by NASA as “big enough to knock modern civilization back to the 18th century” — barely ...
NASA says the sun is in the highly active "maximum phase" of its 11-year solar cycle.. That means there will probably be big solar storms bringing beautiful aurora in the next year or so. Solar ...
The start of solar cycle 25 was declared by SIDC on September 15, 2020 as being in December 2019. [9] This makes cycle 24 the only "11-year solar cycle" to have lasted precisely 11 years. Details of cycles 1 to 25
By 2012, consensus was a small cycle, as solar cycles are much more predictable 3 years after minima. In May 2009 the NOAA Space Weather Prediction Center's Solar Cycle 24 Prediction Panel predicted the cycle to peak at 90 sunspots in May 2013. [11] In May 2012 NASA's expert David Hathaway predicted a peak in Spring of 2013 with about 60 ...
