Noch ein M-Flare

[Roland Harter]

derzeit schon M1.1 noch steigend.

Quelle?

Im http://sec.noaa.gov/sxi/current_sxi_4MKcorona.png sind zwei leuchtende Stellen, eine müsste 786 sein, die andere am Rand ??

M3.0 scheint das Ende zu sein.

Hallo Roland,

zumindest gab es einen Typ II Radio-Sweep:

Ich erwarte mir aber trotzdem nichts, das Ding war zu impulsiv.
Viele Grüße

Hallo zusammen,

Ralf, der M3 ist ja nicht gerade sehr stark, aber immerhin war er doch ein halbe Stunde im M - Bereich.

Ich will mal zur Diskussion stellen, wann oder besser wie kurz ist es ein "impulsiver" und ab wann nicht mehr ?

Halte uebrigens Ausschau zum Eintreffen des ersten M´s vom Freitag.

Gruss
Peter

hallo peter,

die erste, wenn auch kleine schockfront ist durch. (kurz vor 3) sieht aber so aus, dass da noch mehr unterwegs ist. leider truebt sich das wetter ein. wobei ich mir eh nicht viel erhofft hatte.

gruss heiko

LASCO/EIT observed a Full Halo Event on 2005/07/09-10. The event was 
first seen in C2 at 22:30 UT all above the NW limb, as a wide and 
ragged loop front front. Faint and diffuse extensions all above both 
poles can also be discerned. By 23:06 UT, the C2 occulting disk is 
already completely covered. Note that the development of a typical 
3-part structure CME can be seen on ENE since 21:54 UT. Signatures 
of the halo event were first seen in C3 at 23:18 UT all above the W 
Limb. A very faint and diffuse front can be seen ahead (shock?) 
spanning all above the N Pole. The C3 occulting disk is completely 
covered by 23:42 UT. The mean plane-of-sky speed of the LE of the halo
CME (where the intensity gradient is maximum) at PA ~ 306 is around 
1140 km/sec, showing practically no acceleration (based on C3 data).

GOES reported an M2.8 X-ray flare on NOAA AR 10786 (N12W28) between 
21:47 - 22:19 UT with peak emission at 22:06 UT. Note also the 
occurrence of a C1.5 X-ray flare on NOAA AR 10789 (N17E15) between
20:23 - 21:01 UT with peak emission at 20:45 UT preceded by a B5.8
X-ray flare on the same AR 10789 that peaked at 19:38 UT. EIT 195 
images show a small brightening on AR 10789 starting at 20:36 UT with
the formation of a dimming region toward NE of the AR afterward. The
eruption of at least part of a filament on NE can be seen more or less
coincident with the development of the dimming. The EIT events just 
described are most likely related to the X-ray activity reported by
GOES on NOAA AR 10789 (and seem to be the EIT counterpart of the 
3-part structure CME seen by the LASCO coronagraphs). Later, at 22:00 
UT, a strong brightening can be seen on AR 10786 followed by the 
formation of a dimming toward NW, N, and NE of the AR. Corresponding 
running difference EIT 195 images show a strong intensity disturbance 
developing radially away of the AR, mainly toward N. The bulk of the
material ejected seems to develop mainly toward NW. These EIT events 
are related to the M2.8 X-ray flare on AR 10786.

In summary, the event has therefore been determined as an asymmetric 
full halo event, frontsided, associated with an M2.8 X-ray flare on 
NOAA AR 10786.

Movies and images of the event (including the event on AR 10789)
will shortly be made available at:
