On 14 August 2010, a C4.4-class flare produced the first solar radiation storm of cycle 24. The proton storm event was minor, rating at S1, and was easily absorbed by the Earth's ionosphere. On 6 November 2010, active region AR11121 emitted an M5.4 flare.
May 2024 solar storms: X1.2(X1.3)-class flares [93] and X4.5-class flare. [94] The flares with a magnitude of 6–7 occurred between 30 April and 4 May 2024. On 5 May the strength of the solar storm reached 5 points, which is considered strong according to the K-index. The rapidly growing sunspot AR3663 became the most active spot of the 25th ...

It's the biggest flare of this 11-year solar cycle, which is approaching its peak, according to NOAA. The sun produced its biggest flare in nearly a decade Tuesday, just days after severe solar ...
Solar flares erupted 21-22 Feb. Seen here from GOES-16; an R3 flare in the NE, followed by an R1 from beyond the SE limb, and another R3 event from the NE again.
Solar flares strongly influence space weather near the Earth. They can produce streams of highly energetic particles in the solar wind, known as a solar proton event. These particles can impact the Earth's magnetosphere in the form of a geomagnetic storm and present radiation hazards to spacecraft and astronauts. A solar flare
Energy released in a solar storm led to increased aurora activity in Earth's atmosphere on Thursday and Friday.
English: The coronal mass ejection starts at 2:36 UTC and ends at 3:56 UTC on August 1 in this animation on STEREO Ahead images. The animation shows the cloud of particles moving away toward Earth at more than 1,000 kilometres per second (3.6 million kilometres per hour), moving more quickly than any other coronal mass ejection in years.
