Update: The X3.1 solar flare did not produce a CME.

Solar alert: Major X3.1 solar flare from AR 2192

The massive sun spot group AR 2192 has done it again tonight, letting off a pretty big solar flare tonight. The X3.1 flare peaked at around 21h40 UT.



AR 2192 produces an X3.1 flare

The flare has caused a big R3 radio blackout across the sunlit part of the world on the HF bands. It also appears to have sparked some sporadic E activity in the VHF bands due to ionization in the E-layer. Aurora is also being reported in Scotland, but this may be a coincidental effect from the flares a couple of days ago. No major CMEs have been seen coming from these flares so far.


The recent aurora seems to have ended

Active sun: Nine "M" flares in 48 hours!

Massive Solar Region AR2192, which is so big that it's naked-eye visible (with suitable solar filters) has been extremely active since it came into view a few days ago. Since producing a non-eruptive X1.1 flare on Sunday, it's popped off no less than nine M-class flares, including an M8.8 at 01h32 UT this morning. It certainly has the potential to produce more X-flares.

UV radiation from the flares is ionizing Earth's upper atmosphere, causing minor radio blackouts on the sunlit side of the earth. Aurora has been visible in the northern latitudes, with occassional forays into the mid-latitudes.


AR2192 is now almost earth-facing, so any major flares over the next 48 hours will surely have the potential to cause some major effects here on earth.

UPDATE: Since this post, an X1.6 flare at 14h28 UT has occurred. No CME has been detected at this stage.
