“The Sun wakes up this week with several new bright regions that have rotated into Earth-view. The newest of these regions has been actively firing solar flares since it was on the Sun’s backside. All this activity has boosted the solar flux so amateur radio operators and emergency responders are enjoying decent radio propagation. Meanwhile some pockets of fast wind continue to pummel Earth, keeping things at unsettled conditions. The wind isn’t fast enough to bring us up to storm levels and bring aurora down to mid-latitudes, but it is enough to help improve GPS
reception at low latitudes. Learn more about the new active regions, when the next solar storm is expected, and what else the Sun has in store for us this week. “
