At http://science.nasa.gov/science-news/science-at-nasa/2010/13dec_globaleruption/ we have a video clip and a story on a sunspot eruption way back in August (see also www.dailygalaxy.com december 14th). What prompted the post was a paper just published in the Journal of Geophysical Research on the electro-magnetic significance of the eruption.

At www.jpl.nasa.gov/news/news.cfm?release=2010-415&cid=release_2010-415 we learn that NASAs Voyager I spacecraft has reached a spot on the edge of the solar system where solar wind is absent, or minimal. It is not expected to pass fully through the heliosphere for another 4 years.
