Spaceweather Aurora Warnung

[Wolfgang Dzieran]

Spaceweather gibt mal wieder eine Aurora-Warnung heraus:

AURORA WARNING: A lopsided full- halo coronal mass ejection (pictured right) raced away from the Sun on March 11 at 2306 UT. Although it was not squarely Earth- directed, the expanding cloud will probably deliver a glancing blow to our planet's magnetosphere on March 14th. High-latitude sky watchers -- e.g., those in northern Europe, Canada, and along the northern tier of US states -- should be alert for auroras this week.

Mal sehen, das am 11.3. kurz vor Mitternacht war ja nur ein C-Flare, aber damit hatten wir ja schon 2000 eine gute Überaschung erlebt, wenn ich mich richtig erinnere. Also soltle man - wenn es denn nicht regnet wie hier bei uns, besonders im Norden der Republik heute und morgen Nacht mal gut aufpassen! Vielleicht ist ja zumindest fotografisch was drin.

Hi,

ich geb' die Info einfach mal so weiter, hatte selber bisher keine Zeit mir die LASCO-Filmchen anzuschauen.

"EIT and LASCO observed a full HALO CME Event 2002/03/11. This event was first seen in C2 begining at 23:06 UT on 2002/03/11 as a double loop front with bright LE and wide cavity. First entering the field at PA 120 degrees and developing to a full HALO with faint material off the West limb. The event was first seen in C3 at 23:42 UT and tracked to 16Rs before a temporary DSN data gap. The plane-of-sky speeds averaged in both fields to 883 km/sec with acceleration through C3.

This event was first seen in EIT at 22:35 UT with a Southward transient dimming of AR 9866 at location [S7.8; E43.5]. The observation was less than good during this period as we were taking cal images and loading a new observation plan.

Images and movies of the event are on the FTP server at:
