A group of three very large sunspots have emerged into view as they rotate from the backside of the sun. These sunspots could be the first feature needed for Northern Lights soon.
The sun is coming out of the sunspot minimum and the number of sunspots are increasing. The newest group of three sunspots are each at least the size of Earth.
Mike Murray, astronomer and Program Director at Delta College’s Planetarium in Bay City, MI, says the sunspots are on the side of the sun today. As the sun rotates, the sunspots will be pointing directly at Earth in an estimated five to six days, according to Murray. Once the sunspots are facing Earth, the chance for Northern Lights increases. The sunspots will point at Earth for about three to four days sometime next week.
