03:30 UT S East Blob-like front starts to be discernible. 04:30 UT NN East Diffuse jet-like front. 08:30 UT S East Slow development of a diffuse expanding loop front. A loop front follows at ~ 16:06 UT. By that time, the southern leg of the former expanding loop is already past the S Pole. The event is first seen in C3 at 16:18 UT, on the SE. By 22:18 UT, the legs intersect the inner edge of the C3 occulting disk at PAs 95 and 215 (~ 120 deg), the loop front exhibiting an assymetrical shape. At PA 125, the plane-of-sky speed of the LE is abut 430 km/sec, the HT profile showing practically no acceleration (based on C3 data). No significant X-ray activity reported by GOES (below the A-level) during the day. 09:54 UT NN East Diffuse jet-like front.
