“We await the arrival of a glancing blow from a mini-solar storm due to hit today. Although its not expected to be a strong impact, effects might be enhanced by some fast solar wind pushing it from behind. NOAA is expecting storm conditions, especially at high latitudes over the next day or so. Solar flux remains at the low end of marginal so while not optimal, HF radio propagation continues to limp along. At least we have no threat for any major flares and radio blackouts. Learn details of these solar conditions and the coming solar storm, catch up on aurora photos from recent activity, and see what else the Sun has in store this week”
