Active region 4478, which appeared in Earth's field of view just three days ago, is rapidly growing and has now reached an area of 825 m.s.p. (a unit of measurement for sunspot area), making it the second-largest active region of the year. Among the approximately 160 sunspot groups recorded since January 1, it is second only to region 4366, observed in the first half of February.
