  2. Coronal hole - Wikipedia

    en.wikipedia.org/wiki/Coronal_hole

    A coronal hole at the Sun's north pole observed in soft X-ray. Coronal hole size and population correspond with the solar cycle. As the Sun heads toward solar maximum, the coronal holes move closer and closer to the Sun's poles. [4] During solar maxima, the number of coronal holes decreases until the magnetic fields on the Sun reverse.

  5. Coronal loop - Wikipedia

    en.wikipedia.org/wiki/Coronal_loop

    In solar physics, a coronal loop is a well-defined arch-like structure in the Sun's atmosphere made up of relatively dense plasma confined and isolated from the surrounding medium by magnetic flux tubes. Coronal loops begin and end at two footpoints on the photosphere and project into the transition region and lower corona.

  6. Stellar corona - Wikipedia

    en.wikipedia.org/wiki/Stellar_corona

    Coronal loops are the basic structures of the magnetic solar corona. These loops are the closed-magnetic flux cousins of the open-magnetic flux that can be found in coronal holes and the solar wind. Loops of magnetic flux well up from the solar body and fill with hot solar plasma. [12]

  8. List of solar storms - Wikipedia

    en.wikipedia.org/wiki/List_of_solar_storms

    A coronal mass ejection (CME) Solar storms of different types are caused by disturbances on the Sun, most often from coronal mass ejections (CMEs) and solar flares from active regions, or, less often, from coronal holes.

  9. Carrington Event - Wikipedia

    en.wikipedia.org/wiki/Carrington_Event

    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]
