Rare Display of Northern Lights Visible Across US, Causing Awe Among Sky-Gazers.
A powerful geomagnetic storm swept across much of the United States on Tuesday and Wednesday, creating a spectacle that allowed people in dozens of states to witness the breathtaking display of the northern lights. The phenomenon, also known as the aurora borealis, is caused by charged particles from the sun colliding with gases in the Earth's upper atmosphere.
Photographs posted on social media showed vibrant, colorful displays of light stretching across the night sky from New York to Washington state, Texas, Oklahoma, and Tennessee. From Nevada to Massachusetts, Georgia, Alabama, Montana, Alaska, Wyoming, California, Louisiana, New Mexico, Florida, South Carolina, North Carolina, Nebraska, Iowa, Idaho, South Dakota, and other states, people marveled at the beauty of the northern lights.
The National Oceanic and Atmospheric Administration's Space Weather Prediction Center had issued a severe geomagnetic storm watch for 11 and 12 November due to fast-moving coronal mass ejections hurled out by the sun. Shawn Dahl, a forecaster at the SWPC in Boulder, Colorado, warned that two or three anticipated CMEs had already reached Earth and "packed quite a punch," causing G4 severe level conditions.
However, forecasters now expect the third CME to arrive around midday on Wednesday, potentially leading to higher levels of geomagnetic activity. According to Marc Chenard, a meteorologist at the Weather Prediction Center, the northern lights could return again on Wednesday night across the country, although cloudy skies may obstruct views for those in parts of the west coast and north-east.
The Space Weather Prediction Center reported that G3 conditions were currently being observed, with a chance for higher levels of geomagnetic activity possible throughout the day.
