  2. Solar flare - Wikipedia

    en.wikipedia.org/wiki/Solar_flare

    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.

  3. List of solar storms - Wikipedia

    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 ...

    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.

  5. Carrington Event - Wikipedia

    en.wikipedia.org/wiki/Carrington_Event

    The March 1989 geomagnetic storm knocked out power across large sections of Quebec, while the 2003 Halloween solar storms registered the most powerful solar explosions ever recorded. On 23 July 2012, a "Carrington-class" solar superstorm (solar flare, CME, solar electromagnetic pulse) was observed, but its trajectory narrowly missed Earth.

    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.

    It was classified as an X1.2 flare.X-class flares are the strongest, and powerful X-class flares have the ability to create world-wide blackouts. Solar flares are ranked by their strength, with ...

  8. Coronal mass ejection - Wikipedia

    en.wikipedia.org/wiki/Coronal_mass_ejection

    CMEs are often associated with solar flares and other forms of solar activity, but a broadly accepted theoretical understanding of these relationships has not been established. If a CME enters interplanetary space, it is referred to as an interplanetary coronal mass ejection (ICME).

  9. Active region - Wikipedia

    en.wikipedia.org/wiki/Active_region

    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]
