According to NASA, nearly 40 CMEs occurred last week, but most did not cause space weather impacts on Earth. This photo shows a vivid northern lights display over a home in Alaska on Nov. 23, 2024.
The 2003 Halloween solar storms had a peak Dst index of −383 nT, although a second storm on 20 November 2003 reached −422 nT while not reaching G5-class. [16] [17] The March 1989 geomagnetic storm had a peak Dst index of −589 nT, [18] while the May 1921 geomagnetic storm has been estimated to have had a peak Dst index of −907 ± 132 nT.

Post-eruptive loops in the wake of a solar flare, image taken by the TRACE satellite (photo by NASA). 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 ...
A solar storm is a disturbance on the Sun, which can emanate outward across the heliosphere, affecting the entire Solar System, including Earth and its magnetosphere, and is the cause of space weather in the short-term with long-term patterns comprising space climate.
