The best time to view auroras is typically between 10 p.m. and 2 a.m., the Space Weather Prediction Center said. They may be seen earlier but are not as active and visually appealing.
There are five geomagnetic storm categories, ranging from G1 (minor) to G5 (extreme). According to NOAA, a category G4 (severe) storm, like the one that’s forecast for this weekend, can cause ...
A geomagnetic storm, also known as a magnetic storm, is a temporary disturbance of the Earth's magnetosphere caused by a solar wind shock wave. The disturbance that drives the magnetic storm may be a solar coronal mass ejection (CME) or (much less severely) a corotating interaction region (CIR), a high-speed stream of solar wind originating ...
The aurora is expected to be bright and visible in multiple northern U.S. states Oct. 3 through Oct. 5 as well as from the lower Midwest to Oregon.
The official planetary K p-index is derived by calculating a weighted average of K-indices from a network of 13 geomagnetic observatories at mid-latitude locations.Since these observatories do not report their data in real-time, various operations centers around the globe estimate the index based on data available from their local network of observatories.
The March 1989 geomagnetic storm included multiple space weather effects: SEP, CME, Forbush decrease, ground level enhancement, geomagnetic storm, etc.. The 2000 Bastille Day event coincided with exceptionally bright aurora. April 21, 2002, the Nozomi Mars Probe was hit by a large SEP event that caused large-scale failure. The mission, which ...
Solar storms include: Solar flare, a large explosion in the Sun's atmosphere caused by tangling, crossing or reorganizing of magnetic field lines; Coronal mass ejection (CME), a massive burst of plasma from the Sun, sometimes associated with solar flares; Geomagnetic storm, the interaction of the Sun's outburst with Earth's magnetic field
The lights, also known as aurora borealis, might be visible as far south as Alabama, according to NOAA.
