Space weather update
Solar activity is at low levels with only the occasional C-class solar flare mainly from sunspot region 2164. There has also not been any clear sign of a Coronal Mass Ejection passage which was expected from a filament eruption back on September 12 (news item) so it does seem likely that there wasn't any ejecta heading towards Earth after all. The Low Energy Protons as measured be ACE EPAM continue to trend back towards background levels which also suggest there is no Coronal Mass Ejection on it's way to Earth.
