source of the cloud appears to be sunspot complex 1185-1186, which experienced an episode of magnetic instability during the early hours of April 9th
Stable or quiescent filaments are believed to lie in and along a magnetic trough. It is thought that the sudden disappearance of such a filament is due to a reconfiguration of the field. In essence, the magnetic trough becomes a magnetic ridge (the bottom of the trough elevating in a period of tens of minutes to become the peak of the ridge). In this process, the filamentary material (cooler gas) is thought to be accelerated into the corona. Hyder's explanation is that, in the case of the Hyder flare, some or even most of the filament material, instead of suffering acceleration and ejection, falls down the sides of the magnetic ridge and interacts with the lower chromospheric material producing the flare. If the infall process is symmetrical, then the double parallel ribbon flare will result, if asymmetrical, then only one ribbon results. If the infall is sporadic, or the material insufficient, then only bright knots of flare are produced. Hyder did calculations to show that the kinetic energy of the infalling material should be sufficient to provide the
A magnificent filament of magnetism is curling around the sun's southeastern quadrant today. Measuring more than 700,000 km from end to end, the vast structure is about twice as long as the separation between Earth and the Moon. Arrows trace the filament's meandering path in this extreme UV image from NASA's Solar Dynamics Observatory:
not easy for such a filament to remain suspended indefinitely above the stellar surface, and indeed a collapse is possible. Filaments falling onto the sun can trigger explosions called "Hyder flares." Is one in the offing? Readers with solar telescopes are encouraged to monitor developments.
Well, I think our luck just ran out

When are this "cloud" going to hit earth in GMT time ??
And whats the worst case senario with these hyper flares ?

Oh, I guess I should have asked you about it first. I check it everyday for over a year and never saw anything higher than a K4
this was the 8th, Just a graze.

I saw the B and B just a little while ago , only now they have B9 and C1. Isn't 9 the highest in B, C, K, X?
