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.
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.
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 ...
Reports initially predicted that the CME could graze Earth, [40] however geomagnetic storms on 30–31 October only reached a moderate K p index of 4. [41] On 3 and 4 November, the K p index reached 8−, equivalent to a G4 geomagnetic storm. [42] This was the most intense geomagnetic storm to hit Earth since September 2017.
This is the third geomagnetic storm to reach G4 status during the current 11-year solar cycle, which began in 2019, officials said.
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. [1] [2]
The lights, also known as aurora borealis, might be visible as far south as Alabama, according to NOAA.
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 ...
