Und nem CME...aber der muss ein paar Minütchen eher losgegangen sein...

http://dxlc.com/solar/May 6: A full halo CME was observed in LASCO C3 images beginning at 18:18 UTC. Material distribution around the disk suggest a centrally placed backsided source in the northern hemisphere. Another and more interesting moderately fast CME was observed nearly simultaneously with most of the ejected material seen over the southeast limb. This was at least a partial halo CME, the presence of the other CME makes it hard to determine the full extent. Its source was the long duration event in region 10758.
ja, das habe ich heute Morgen mit etwas Verwunderung zur Kenntnis genommen.Daniel Ricke hat geschrieben:Der dxlc spricht zusätzlich von einem nahezu simultanen full-halo backside CME.

LASCO/EIT observed complex event on 2005/05/06. A Partial Halo event
was first seen in C2 at 17:28 UT as a bright and wide loop front
(hereafter Event #1) above the SE Limb. By 17:54 UT, faint and diffuse
extensions can be seen above the W Limb and N Pole (Event #2). The
Event #2 surrounds the C2 occulting disk by 18:06 UT. The Event #1 was
first seen in C3 at 17:42 UT appearing above the SE Limb, while the
Event #2 shows up at 18:18 UT just above the N Pole. The Event #2
surrounds the C3 occulting disk by 19:12 UT. The Event #1 spans ~
185 deg by 21:18 UT (LE almost at the end of the C3 FOV), from PA 25 -
210. The mean plane-of-sky speed of the LE of Event #1 (based on C3
data) at PA 108 was ~ 1100 km/sec, showing an slight deceleration. As
for the Event #2, the mean C3-plane-of-sky speed of the LE at PA 355
was about 675 km/sec, showing practically no acceleration.
GOES reported a long duration C8.5 X-ray flare on NOAA AR 10758 (S09E29)
between 16:03 - 18:09 UT with peak emission at 17:05 UT. EIT 195 images
show a strong brightening on the aforementioned region starting at
16:12 UT. A big change in the magnetic field topology in and around the
AR between the frames taken at 16:24 and 17:21 UT (no frames in between) can
be observed. By 17:21 UT post-flares loop begin to appear as well as
dimming regions to N and S of the AR. By that time, EIT 195 running
difference images show a huge intensity disturbance all across the
eastern hemisphere. The signatures observed in EIT clearly indicate the
association of the X-ray event with the Event #1 observed by LASCO C2/C3.
It is difficult to say whether the Event #2 is part of the Event #1 or
signature of an apparently backsided CME with source region on the northern
hemisphere. Observation of the evolution of the complex event in C3 seems
to indicate that the latter is more likely.
In summary, the Event #1 has therefore been determined as a Partial Halo
CME, frontsided, associated with a long duration C-class X-ray flare
on NOAA AR 10758. A faint full halo CME (Event #2), apparently backsided,
developed by the time.
Movies and images of the complex event will shortly (I hope) be made
available at:
ftp://ares.nrl.navy.mil/pub/lasco/halo/20050506
(I'm actually abroad and experiencing technical difficulties to access
my software resources. I do apology for that).
Best wishes,

PS: I was attending during the past week a meeting in Europe and therefore
was not able to report in time the Halo events occurred during first days
of May. The corresponding analysis of the events will be made as usual and
made available through the LASCO CME List in about a week and a half time.
Thanks for your understanding.
