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.
Three solar flares occurred over a 24-hour period this week. While we may not see them with a naked eye, they can affect Earth. Here's how.
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 ...
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.
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 ...
In solar physics and observation, an active region is a temporary feature in the Sun's atmosphere characterized by a strong and complex magnetic field.They are often associated with sunspots and are commonly the source of violent eruptions such as coronal mass ejections and solar flares. [1]
The first CME scheduled to reach our planet on New Year's Eve is likely associated with a recent M2 solar flare. The CME left the sun on Sunday at 1 a.m. ET, according to SpaceWeatherLive .
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.
