Richard Christopher Carrington (26 May 1826 – 27 November 1875) [2] was an English amateur astronomer whose 1859 astronomical observations demonstrated the existence of solar flares as well as suggesting their electrical influence upon the Earth and its aurorae; and whose 1863 records of sunspot observations revealed the differential rotation of the Sun.
The first visible and electromagnetic effects of a solar flare reach observers on Earth at the speed of light, which means they were spotted about eight minutes after they occurred on the surface ...
Solar cycle 24 (2008–2019) Solar cycle 25 is the current solar cycle, the 25th since 1755, when extensive recording of solar sunspot activity began. It began in December 2019 with a minimum smoothed sunspot number of 1.8. [ 2] It is expected to continue until about 2030. [ 3][ 4]
The solar storms of May 2024 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. The geomagnetic storm was the most powerful to affect Earth since March 1989 , [ a ] and produced aurorae at far more equatorial latitudes than usual in both ...
The good news is that Earth should be out of the line of fire this time because the flare erupted on a part of the sun moving away from Earth. NASA's Solar Dynamics Observatory captured the bright ...
The exaggerated solar flare activity creates more disturbance, measured on a scale called a K-index, which ranges from 0 to 9, with 9 having the most activity. Friday is expected to have a K-index ...
In solar physics, a solar particle event ( SPE ), also known as a solar energetic particle event or solar radiation storm, [ a][ 1] is a solar phenomenon which occurs when particles emitted by the Sun, mostly protons, become accelerated either in the Sun's atmosphere during a solar flare or in interplanetary space by a coronal mass ejection shock.
Magnetospherics. Solar phenomena. v. t. e. 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.
