Points Of Interest
2006/04/21 (Friday)
01:31 UT W Limb Reconnection event very close to the limb. The feature
coming out is first seen in C3 at 02:42 UT, a little
bit to N of the event described in entre at 22:30 UT on
previous day. GOES recorded a B4.5 X-ray flare on
NOAA AR 10871 (S05W90) between 00:41 - 00:58 UT with
peak emission at 00:49 UT.
01:54 UT ES East Faint and diffuse loop-like front preceding the
development of a system of diffuse and expanding loop
fronts. Some extremely faint extension can be since
since late on previous day expanding toward the S Pole.
The system partly superposes in the LOS with a brighter
(though slower and elongated) system on E that develops
slightly toward ESE.
03:30 UT EN East Ragged blob-like front.
07:31 UT N West Very thin fan-like front that fades throughout C2.
16:54 UT S East System of faint exapnding loop fronts. It fades
throughout C3.
19:31 UT WN West Diffuse jet-like front.
22:30 UT N West Diffuse and extremely faint front preceding the
development of a system of very faint expanding fronts.
This faint system fades throughout C3.

E Limb Gusty outflow all along the day.
14:30 UT E Limb Diffuse and extremely faint front preceding a brighter
feature to N (first clearly seen at 15:54 UT) that
fades throughout C3. Some very faint and diffuse
extensions above the E limb.
18:54 UT S West Faint and elongated loop-like front. It fades very
close to the inner edge of C3.
2006/04/23 (Sunday)
E Limb Some gusty outflow all along the day.
01:54 UT N East Faint fan-like front.
05:30 UT EN East Couple of brightenings that quickly fade.
14:30 UT EN East Elongated fan-like front. Some faint loop-like fronts
follow (both on ENE and ESE)
15:06 UT S West Extremely faint expanding (toward S) front. Barely
discernible in C3.
20:06 - 24:00 UT Temporary Data Gap.
