how long can a solar flare knock out power
Geomagnetic storm According to a study by Metatech corporation, a storm with a strength comparable to that of 1921 would destroy more than 300 transformers and leave over 130 million people without power in the United States, costing several trillion dollars.[27] The Daily Mail even claims that a massive solar flare could knock out electric power for months, but[28] these predictions are contradicted by a NERC report that concludes that a geomagnetic storm would cause temporary grid instability but no widespread destruction of high-voltage transformers. The report points out that the widely quoted Quebec grid collapse was not caused by overheating transformers but by the near-simultaneous tripping of seven relays.[29]
Solar eclipse of April 8, 2024 A total solar eclipse will take place on Monday, April 8, 2024, visible across North America. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. With a magnitude of 1.0566, its longest duration of totality will be of four minutes and 28 seconds near the town of Nazas, Durango, Mexico, and the nearby city of Torreón, Coahuila.
