Massive sunspot glares at the Earth
Abstract
A huge sunspot has been seen within firing rage of the earth. "Yesterday, sunspot AR3038 was big. Today, it's enormous," Tony Phillips, author of SpaceWeather, wrote on Wednesday. Sunspots have an 11-year cycle, growing stronger towards the end of the cycle. Interestingly, sunspots are actually cooler than other parts of the sun. "If you have a couple of rubber bands twisting around on your finger, they eventually get twisted too much, and they break. The difference with magnetic fields is that they reconnect. And when they reconnect, it's in that process that a flare is generated." In case a sunspot blasts out coronal mass ejection( CME), the charged parts could react with the earth's magnetic fields and cause a colorful light display in the atmosphere. Experts remain observant, with NASA and NOAA watching the sunspots for any significant changes. For now, there is no cause for alarm or anything to fear about the sunspots.
