The rapidly growing sunspot AR3663 became the most active spot of the 25th solar cycle. On 5 May alone, it emitted two X-class (strongest) flares and six M-class (medium) flares. Each of these flares resulted in a short-term but profound disconnection of the Earth's radio signal, resulting in signal loss at frequencies below 30 MHz. [95]
The Carrington Event was the most intense geomagnetic storm in recorded history, peaking on 1–2 September 1859 during solar cycle 10.It created strong auroral displays that were reported globally and caused sparking and even fires in telegraph stations. [1]
The solar storms of August 1972 were a historically powerful series of solar storms with intense to extreme solar flare, solar particle event, and geomagnetic storm components in early August 1972, during solar cycle 20. The storm caused widespread electric- and communication-grid disturbances through large portions of North America as well as ...
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.
It's the biggest flare of this 11-year solar cycle, which is approaching its peak, according to NOAA. ... NASA's Solar Dynamics Observatory captured the bright flash of the X-ray flare. It was the ...

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 solar storms of May 2024 (also known as 2024 Mother's Day solar storm [1] or Gannon storm in memory of Jennifer Gannon, [2] a space weather physicist [3]) were a series of powerful solar storms with extreme solar flares and geomagnetic storm components that occurred from 10–13 May 2024 during solar cycle 25.
