Solar Flare Alert
Tonight's X2.1 flare appears to be a long-duration flare which is still ongoing.
It's coming from active region AR3842 which gave us the X7 and X9 flares last week. It's now rotated close to the west limb so is unlikely to throw any CMEs (coronal mass ejections) in our direction. The solar flares will, though, still cause radio blackouts on the HF radio bands (and noise on higher frequencies due to radio bursts) on earth's dayside as long as they're on this side of the sun.
