“The fast solar wind we have been enjoying over the past week from an extended coronal hole is finally beginning to wane. We will likely remain at unsettled conditions over the next few days and return to quieter conditions by the end of the week. We also have 3 new bright active regions on the Earth facing Sun that are boosting solar flux for amateur and shortwave radio operators and emergency responders. This means radio propagation is back to marginal levels on Earth’s day side and will likely remain that way over the next week. See the details of these bright regions, catch up on aurora photos from the recent solar storms, and see what else our Sun has in store this week!”
