Info/Session URL: None Entered
Note:

Triangulation between SOHO LASCO C2/C3 and STEREO A COR2 with a higher degree of uncertainty. This is due to the lack of clean observed source, faint leading edge in SOHO LASCO, a large data gap in STEREO A COR2 spanning most of this event, and the lobed front which is partially chopped off for this analysis focusing on the main equatorial lobe best viewed from COR2A. While uncertainty lies in the latitude, longitude, and half width, there is higher certainty in the speed being <=250 km/s.
