01:54 UT WN West Diffuse front that quickly fades.
06:54 UT N Pole Diffuse and elongated fan-like front.
06:54 UT WS West Thin and elongated fan-like front precedes an
elongated loop front (~ 08:54 UT). The loop front
fades throughout C3, not far from its inner edge.
11:30 UT S East Faint feature precedes the development of a ragged
loop front with faint asymmetric extensions that
expand toward S (difficult to give an exact time of
first appearance). The extensions cross the S pole.
The ragged loop front is first seen in C3 at 15:18 UT.
Its width in C3 by 19:42 UT is ~ 30 deg. The extensions
are barely discernible.
