‘Monster sunspot‘ could bring solar flares
A group of sunspots 11 times wider than the Earth turned to face Earth planet, raising the possibility of solar flares and auroras, CBS news reported. More than 60,000 miles wide, Sunspot Region 1476 became visible over the weekend and two coronal mass ejections (CMEs), where a portion of the sun's atmosphere breaks off, erupted on Tuesday, the report said. NOAA’s Space Weather Prediction Center said the CMEs blasts could cause moderate geomagnetic storms and auroras in the higher altitudes. The CMEs are traveling at 1.5 million miles per hour but, since they are only partially directed at Earth, they aren’t expected to affect communications satellites or other equipment susceptible to space weather, CBS news said. Scientists at NASA’s Space Dynamics Observatory called Sunspot Region 1476 a “monster sunspot” because it is so large and noticeable. The spot is so large that people have been able to see it without the aid of telescopes, said Spaceweather.com. Photographers should only view it through the camera’s LCD, it warns. |
