ein paar wenige LASCO-Bilder (C2/C3) sind inzwischen eingetrudelt:Daniel Ricke hat geschrieben:LASCO ist echt mal wieder zum Schreien. Sollten doch noch mal die wichtigen Bilder kommen, so rechne ich etwa in 2 Tagen damit....
Full Halo Event on 2006/12/13, frontsided
LASCO/EIT observed a Full Halo Event on 2006/12/13. The event was first
seen in the LASCO C2 FOV at 02:54 UT as a very bright and wide loop front
all above the S Pole, preceded by a diffuse front that fully surrounds
the occulting disk (signal barely above the limb on N, almost at the end
of the C2 FOV on the S). An increase of cosmic rays (proton storm) starts
to be observed at 03:06 UT; by 03:34 UT the images are almost fully
degraded by the ongoing proton storm. The event is first seen in C3 at
03:18 UT, all above the S Pole. The bulk of the CME heads toward S (as
projected onto the plane of the sky). The C3 occulting disk is fully
surrounded by 03:42 UT. The mean plane-of-sky speed of the LE (as
measured at the edge of the brightest part of the LE) at PA ~ 190 deg
was ~ 1440 km/sec. If measured at the outermost edge of the event (i.e.,
that of the diffuse front ahead of the bulk of the CME) the plane-of-sky
speed is ~ 1800 km/sec (both determinations based on C2 and only a
couple of C3 frames - afterward images too degraded by the ongoing
proton storm).
GOES recorded a X3.4 X-ray flare on NOAA AR 10930 (S06W23) between
02:14 - 02:57 UT with peak emission at 02:40 UT. EIT 195 images show a
sudden increase in brightness on AR 10930 by 02:24 UT. A rather circular
wave (and dimming) with epicenter on the AR mentioned can be seen
afterwards quickly covering the full disk.
In summary, the event has therefore been determined as a full halo event,
frontsided.
Movies and images of the event will shortly be made available at:

Welches aber nur die letzten 24h betrachtet.nein, keine Anzeichen; ja, Du deutest falschBenjamin Witt hat geschrieben: jetzt wundert mich aber, dass ich auf dieser seite hier ---> http://www.meteoros.de/polar/polwarn.htm meiner meinung anch keine anzeichen für polarlichter sehe.
oder deute ich da die grafiken falsch?
