Welcome to August! The year 2018 is now 212 days old and according to the numbers from the NOAA SWPC, the Sun has been spotless during 120 days this year thus far. The sunspots regions that did face Earth this year have been far from impressive and we had no M or X-class solar flares yet this year.
A lot of people come to SpaceWeatherLive to follow the Sun's activity or if there is aurora to be seen, but with more traffic comes higher server costs. Consider a donation if you enjoy SpaceWeatherLive so we can keep the website online!
