04:54 UT N West Faint and diffuse ragged front.
09:54 UT N West Very thin and elongated front followed at 13:32 UT by
a faint and veru diffuse elongated front. They fade
throughout C2.
11:30 UT ES East 'Explosive' ragged loop front. Some infalling material.
GOES reported a C1.1 X-ray flare from NOAA AR 10693
(S14E53) between 10:51 - 10:57 UT with peak emission
at 10:55 UT.
00:06 UT ES East Ragged loop front preceded by a faint expanding loop
front. It fades throughout C3.
02:30 - 05:30 UT Temporary Data Gap.
05:30 UT WN West Faint and big ragged front already under development
after data gap. Later:
* by 06:54 UT on W, a bright and wide ragged loop front,
* by 07:31 UT, faint circular extensions are discernible
all above the E - SE - S Limb. The extensions are not
discernible in C3.
* at 09:30 UT, a big expanding loop front follows right
above the W Limb,
* at 12:06 UT, a bright loop front developing mainly
toward WSW follows.Circular extensions on NW and all
above the E - SE - E Limb are discerned. The extensions
are not visible in C3,
* at 15:06 UT, a relatively small ragged loop front on W,
(HALO) * at 16:54 UT, another bright ragged loop front developing
slightly toward WSW. By 17:30 UT, faint circular
extensions are discernible above the E - SE - E Limb,
and also on NW. An even fainter and diffuse front seems
to develop also on NE. By 18:18 UT, the event looks
like a very asymmetric 'full' halo CME in C3,
* at 18:06 UT, a relatively small and asymmetric loop
front follows,
* and by 20:30 UT, a diffuse and asymmetric loop front
develops slightly toward WNW.
On the other hand, GOES reported lot of X-ray activity
on NOAA AR 0691 since late on previous day. In
particular, on 2004/10/30:
- a C9.7 X-ray flare (N14W19) between 00:39 - 00:53 with
peak emission at 00:49 UT,
- a M3.3 X-ray flare (N13W20) between 03:23 - 03:37 with
peak emission at 03:33 UT,
- a M4.2 X-ray flare (N13W22) between 06:08 - 06:22 with
peak emission at 06:18 UT,
- a C5.5 X-ray flare (N16W22) between 06:55 - 07:05 with
peak emission at 07:01 UT,
- a M3.7 X-ray flare (N14W24) between 09:09 - 09:30 with
peak emission at 09:28 UT,
- a C7.2 X-ray flare (N13W25) between 10:20 - 10:41 with
peak emission at 10:35 UT,
- a C1.0 X-ray flare (N12W26) between 11:17 - 11:27 with
peak emission at 11:22 UT,
- a X1.2 X-ray flare (N13W25) between 11:38 - 11:50 with
peak emission at 11:46 UT,
- a C2.6 X-ray flare (N12W27) between 13:59 - 14:10 with
peak emission at 14:06 UT,
- a M5.9 X-ray flare (N13W28) between 16:18 - 16:37 with
peak emission at 16:33 UT (this is the one most likely
associated to the HALO CME at 16:54 UT).
Please also note that there was a C3.7 X-ray flare
from NOAA AR 0687 (N13W59) between 12:45 - 13:03 UT
with peak emission at 12:51 UT.
19:54 UT ES East Elongated loop front.
01:31 UT W Limb Ragged loop front.
01:54 UT N West Asymmetric and diffuse expanding loop front.
03:30 UT ES East Spray-like front that fades close to the inner edge of
C3.
03:30 UT N East Elongated and diffuse loop front that feades throughout
C2.
06:30 UT WS West Ragged loop front followed by gusty outflow. GOES
reported an M2.3 X-ray flare from NOAA AR 0691 (N12W36)
between 05:23 - 05:39 UT with peak emission at 05:32 UT.
Extremely faint extensions seem to surround the C2
occulter during the development of the event. However,
no extensions can be seen in C3.
12:06 UT N West Faint elongated loop front.
18:30 UT ES East Elongated expanding loop front preceded by a diffuse
and also elongated loop front from which is difficult
to give an exact time of first appearance.
20:30 UT W Limb Elongated and ragged loop front. It fades throughout C3.
22:30 UT W Limb Big ragged loop front and gusty outflow. GOES reported
a C7.0 X-ray flare from NOAA AR 0691 (N11W45) between
21:08 - 021:38 UT with peak emission at 21:27 UT.
00:54 UT W Limb Ragged loop front. GOES reported a B7.8 X-ray flare
(N13W48) between 00:34 - 00:40 with peak emission at
00:38 UT.
03:54 UT W Limb Bright ragged loop front. Faint extensions ahead to N.
An extremely faint circula halo seems to develop in
C2 starting at 04:54 UT, which is not discernible in C3.
On the other hand, GOES continues reporting lot of
X-ray activity on NOAA AR 0691. In particular, an M1.1
X-ray flare (N12W49) between 03:04 - 03:26 with
peak emission at 03:22 UT. EIT 195 images show a strong
brightening on NOAA AR 0691 at ~ 03:24 UT followed by
an intensity disturbance toward W and S.
06:06 UT W Limb Big and very wide loop front and trailing material.
Proton storm starting at ~06:30 (C2 time). The event is
very fast, and it is first seen in C3 above the W Limb
at 06:42 UT. By 08:18 UT seems to have completely
surpassed the CME reported to start at 03:54 UT. EIT
195 images show a big CME coming from behind the W Limb,
starting at 05:48 UT.
