A New Solar Flare from the Sun’s Western Limb
SOLAR FLARE ALERT: Earth-orbiting satellites have just detected a M1.7 class solar flare at 21-Aug-2026 at 09:57:00 UTC (04:57:00 AM CDT). An R1 (minor) radio blackout is possible on the sunlit side of Earth.
UPDATE: The M1.7 flare came from sunspot 4507 at solar coordinates N3W89. That is right at the Sun’s limb.
What this means: the flare site is directed almost entirely away from Earth. Spectacular to image, but not a threat to our geomagnetic field.
