A solar flare from a sunspot region associated with this activity and preceding this period produced the then largest flare detected during the Space Age at about X20 (the first event to saturate spaceborne monitoring instruments, this was exceeded in 2003) but was directed away from Earth.
A solar flare is a relatively intense, localized emission of electromagnetic radiation in the Sun's atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other eruptive solar phenomena. The occurrence of solar flares varies with the 11-year solar cycle.
The flares and CMEs of the August 1972 solar storms were similar to the Carrington event in size and magnitude; however, unlike the 1859 storms, they did not cause an extreme geomagnetic storm. The March 1989 geomagnetic storm knocked out power across large sections of Quebec , while the 2003 Halloween solar storms registered the most powerful ...
A growing body of research is finding evidence of violent solar flares deposited in natural archives like tree rings and glacial ice.. Scientists have so far identified five extreme solar particle ...

The peak of Solar Cycle 25 started in January and goes through October, which means we could see more solar flares in the coming months. Solar flares decrease as the sun nears solar minimum.
Solar flares decrease as the sun nears solar minimum. So, throughout the 11-year solar cycle, flares may occur several times a day or only a few times per month, according to NASA.
Since 1996, geomagnetic storms and solar flares have been monitored from the Solar and Heliospheric Observatory (SOHO) satellite, a joint project of NASA and the European Space Agency (ESA). Extreme geomagnetic storms were registered in 2003 and 2024, both sparking northern lights as far south as Florida.
