Points Of Interest
2006/05/17 (Wednesday)
S West Slow development of a system of faint loop fronts since
late on previous day (difficult to give an exact time
of first appearance). By 08:54 UT, a brighter feature
appears, also gradually developing [1]. EIT 195 images
show a filament eruption on SW between ~ 06:36 -
08:36 UT.
03:30 UT E Limb Diffuse front that fades throughout C2. Another front
follows at ~ 05:30 UT. By ~ 06:54 UT, the slow
development of a system of faint loop fronts can be
discerned. Pseudo-continuous outflow superposes in
the LOS, all along the day.
08:30 UT N Pole Faint and diffuse jet-like front.
14:54 UT N West Thin and very elongated fan-like front that fades
close to the innner edge of C3.
23:06 UT S West A brighter feature can be seen at around the PA of the
southern leg of the trailing material of the event
reported at the beginning of this report [1]. Afterward,
twisted material can be discerned, well into next day.
