Farside Flare Players Rotate into View! | Space Weather Weekend 28 May 2026

This week we keep a watchful eye on an active sun with ten sunspot clusters now in Earth view, dominated by activity along the east limb. Newly arrived regions 4446, 4447, and 4455 are firing solar flares and lunching solar storms, although none are earth-directed yet. Region 4441 launched a massive solar storm as it rotated off the west limb of the Sun that gave us some great eye-candy, but its headed towards the farside. That being said, it was strong enough to trigger an S1 radiation storm that has been creating a bit of extra noise on the amateur radio bands. Luckily, the radiation storm is waning and we should be back to normal levels within the next 24 hours. Fast solar wind driven by coronal holes is creating a “bumpy ride” for near-Earth space, and with SDO, STEREO, and Solar Orbiter providing full-sun coverage, the forecast calls for a 40% chance of M-class flares, potential R1–R2 radio blackouts, and a 35% chance of minor geomagnetic storm conditions for high-latitude aurora photographers over the coming days, while GPS users and polar aviation remain largely unaffected.
