When we combine the narrower and broader fields of view of SOHO's coronagraphs, we can easily track in one image the path of two solar storms (likely coronal mass ejections) as they expand into space (Jan. 13-14, 2011).
This combining of images is quite easy to do with the newly released JHelioviewer software, described in the recent Hot Shots web area here.
Before that was released, the effort to overlay images was time-consuming and took a considerable level of skill.
Both of these storms were identified as events from the far side of the Sun that were not headed toward Earth.
