Solar wind stream blowing from big coronal hole, new sunspot regions forming

coronal-hole-solar-wind-stream-sunspot

The dark vertical coronal hole, about 120,000 km wide and more than a million km long, stretches in the center of the Sun. A solar wind stream flowing from the indicated coronal hole should reach Earth on Jan. 16-17, possibly sparking auroras at high-latitudes. Coronal holes are places where the sun’s magnetic field opens up and allows the solar wind to escape.

New sunspots formed yesterday, including fast growing Sunspot 1396 in the northern hemisphere. A second region AR 1397 formed in the southern hemisphere and third sunspot is forming just to the southwest of existing region 1395, and was numbered 1398. An active region is hiding on the northeast limb and will soon begin to rotate into direct Earth view. An explosion Thursday morning, produced a Coronal Mass Ejection (CME) off the northeast limb. That blast registered as a very long duration C-Class flare. (Watch the video!) (SolarHam)
