2005/04/05 (Tuesday)
06:50 UT W Limb Diffuse front that quickly fades.
09:26 UT N West Very faint and diffuse loop front. By 11:26 UT a
faint and expanding loop front starts to be
discernible at ~3.35 solar radii (PA ~315). A jet-
like front develops by 14:50 UT at a PA that matches
the PA of the northern leg. Reconexion event on
NNW by 18:06 (pair formation).
12:50 UT S East Diffuse front preceding the development of a bright
loop front with twisted interior and trailing material.
Gusty outflow in the form of small ragged fronts
precede the whole event.
