Major solar flare watch!

[Ulrich Rieth]

A very active region is on the suns eastern limb. It has not been numbered by NOAA/SWPC so far, but it will probably be known as 11302.
It produced a X1.4 solar flare at 11 UTC on 2011/09/22.
Further major M and X-class flares are possible.
This first X-class flare of the region also produced a very fast coronal mass ejection off the east limb.
As the region rotates further to the earth-facing side of the sun, any eruption in about 4-6 days should be geoeffective.
There seems to be a high potential of very good solar activity in the days ahead and maybe also high potential for episodes of bigger geomagnetic activity next week.
Keep looking at the sun and the forum in the coming days.
Updates will be posted as events unfold.
Clear skies!

Region 11302 did a couple of more flares in the recent days.
At the time of writing there is a major long duration flare in progress (M6.9 so far).
Earlier today the region produced a more impulsive X1.9 flare with type II and type IV radio events and a fast CME.
More flares, also major ones can be expected.
The region will rotate to more geoeffective positions early next week.
If the flarering continues until then, major geomagnetic effects can also not be ruled out.
Clear skies!
