A Fleeting Sunspot & A Familiar Hole | Space Weather News 12-19-2019

This week our Sun’s activity picks up a little bit. We have a small coronal hole that is rotating through the Earth-strike zone and the fast wind it is sending us is causing aurora at high latitudes. Although we have seen this coronal hole before, it is closing so the fast wind is much weaker this time around. Expect unsettled conditions over the next few days and aurora that will likely stay confined to high latitudes. In addition to the fast solar wind, we are also seeing another solar cycle 25 bright region rotating into Earth-view on the Sun’s east limb. This region has briefly emerged strongly enough to become a sunspot, but it likely wont last long enough to get an official number designation before it disappears below the Sun’s surface again. Nonetheless, it is yet another indicator of the new cycle that is nearly here! Learn details of the current fast wind hitting Earth, how the new bright region is affecting radio propagation as well as GPS reception on Earth’s dayside, and see what else our Sun has in store!
