Hallo Peter .
Das wusste Ich nicht,das CME mit dem Zeit langsamer wird.
Danke.
Wojtek.
ex 365 produziert einen ersten X-class flare...

noch mehr Verwirrung gefällig?
Hi Wojtek!
> Das wusste Ich nicht,das CME mit dem Zeit langsamer wird.
Es gibt nämlich auch CME's die sich "nachbeschleunigen".
Sowas passiert z.B. evtl. dann, wenn vorher schon ein schneller CME den Weg freigeräumt hat.
Folgt jetzt ein zweiter CME mit ähnlicher Geschwindigkeit recht schnell nach, so kann dieser quasi auf der Welle des Ersten reiten.
Und dort wird er dann immer schneller...
Gruß

Halo CME Mail
LASCO and EIT observed a 'full halo CME' on 2003/06/15. The
event was first observed in C2 at 23:54 UT as a bright loop
front over the E limb; this had developed to a full halo
CME by 00:30 UT, albeit faint in the E. The front first
appeared in C3 at 00:18 UT with full coverage of the C3
occultor by 01:42 UT. The mean plane-of-sky speed for this
event was 2002 km/s at PA87 , with possible evidence for
moderate deceleration, though this could easily be due to
significant measurement errors of the faint front far into
the C3 field of view.
The CME was probably most associated with an X1.3 X-ray flare
observed by EIT between 23:48 - 00:24 UT, centered at S05E78
with peak emission at 00:00. GOES records this flare from
AR 0386 (probably old AR 0365) at S07E80 between 23:25 - 00:25 UT
with peak emission at 23:56 UT. No obvious EIT wave nor dimming
were observed in association with this event. Considering the
location of the flare and the faint emission in the W hemisphere
this event has been determined probably frontsided.
Movies and images of this event are available at:
ftp://ares.nrl.navy.mil/pub/lasco/halo/20030615
Apologies for the rather late sending of this report. I am
attending the AAS-SPD meeting in Laurel, MD all week. If
similar activity continues from AR 0386, please bear in
mind that these reports will not appear until late in
the day.
Best wishes,
Gareth Lawrence.
