The stunning aurora borealis, caused by solar flares, is expected to be visible again on Sunday night across much of the United States as the geomagnetic storm continues. According to a report by Mike Bettwy, the operations chief of the Space Weather Prediction Center, there is a chance that the intensity of the aurora could be comparable to what was witnessed on Friday night. Bettwy emphasized that darker skies increase the likelihood of spotting the celestial display. However, the report notes that the forecast of rain in the central US could make it difficult to see the northern lights. On a more positive note, meteorologist Tony Fracasso of the National Weather Service’s Weather Prediction Center predicts that the clearest skies are expected in much of the West, as well as from Ohio to the Mid-Atlantic region, and possibly in North Dakota and Minnesota.
