Hallo,
es wird zwar der M1/2n aus 9727 (S22W36) mit Maxi. 1451 UT genannt,
nicht aber der CME vom Westrand, der hier 1418 UT schon weit draußen ist: http://sohowww.nascom.nasa.gov/data/rea ... 418_c3.gif
Der CME zum Zeitpunkt des X 2.8 wird als vermutlich n i c h t erdgerichtet geschätzt, womit allerdings noch nicht klar ist, ob dieser mit dem X 2.8 seine Ursache hat.

KORR.: X 2 ....associated with...., ..., and a CME
SDF Number 345 Issued at 2200Z on 11 Dec 2001
IA. Analysis of Solar Active Regions and Activity from 10/2100Z
to 11/2100Z: Solar activity increased to high levels. Region 9733
(N15E32) produced an impulsive X2/Sf flare at 11/0808 UTC. The flare
was associated with Type II and IV radio sweeps, a 2600 sfu
Tenflare, and a coronal mass ejection (CME) that did not appear to
be Earth-directed. Region 9733 showed increased area and magnetic
complexity with at least one magnetic delta configuration within its
northern-most trailer spots. Region 9727 (S22W36) produced an
impulsive M1/2n flare at 11/1451 UTC associated with relatively
minor radio emission. This region showed minor growth in spot number
and area with two delta magnetic configurations evident within its
large trailing spot mass.
IB. Solar Activity Forecast: Solar activity is expected to be at
moderate to high levels. Isolated M-class flares are expected from
Regions 9727 and 9733. Either region could produce a major flare
during the period as well.
IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z:
Geomagnetic field activity was at quiet levels.
IIB. Geophysical Activity Forecast: Geomagnetic field activity is
expected to be at quiet to unsettled levels through the period.
There will be a chance for a proton flare from Regions 9727 and
9733.
