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.
The sun has been especially active over the last 48 hours. It's released many M-class solar flares as well as an X-class flare — the most powerful type. The radiation from these flares travel at ...

The aurora is expected to be bright and visible in multiple northern U.S. states Oct. 3 through Oct. 5 as well as from the lower Midwest to Oregon.
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.
On 8 May 2024, a solar active region which had been assigned the NOAA region number 13664 (AR3664) produced an X1.0-class and multiple M-class solar flares and launched several coronal mass ejections (CMEs) toward Earth. [6] On 9 May, the active region produced an X2.25- and X1.12-class flare each associated with a full-halo CME.

As at Feb 20, 2025, solar cycle 25 is averaging 37% more spots per day than solar cycle 24 at the same point in the cycle (Feb 20, 2014). Year 1 of SC25 (Dec 2019 to Nov 2020) averaged 101% more spots per day than year 1 of SC24.
