The K7RA Solar Update

The past week saw increased solar activity, with average daily sunspot numbers rising from 5.3 to 19.6 and average daily solar flux from 69.8 to 74.5. We haven’t seen such strong activity since the beginning of last summer, when ARLP016 in 2018 reported average daily sunspot number at 22.6 and average daily solar flux at 75.3. But sunspots only persisted …
