Look for improved propagation on the upper HF bands, as both the sunspot numbers and 10.7-centimeter radio flux remain near or above 100. According to NOAA's Space Weather Prediction Center (SWPC), the increase in activity is being fueled primarily by sunspot Region 4551, which is described as the largest and most complex of six sunspot regions currently visible on the surface of the Sun. Mostly quie...
