Solar wind shock wave arrived at Earth

A slow shock wave arrived today around 08:25 UTC at DSCOVR. The source is unclear but it could have come from a filament eruption back on 6 January or one that took place on 8 January. The resulting coronal mass ejections were not expected to arrive at Earth but one of these two eruptions likely grazed our planet today.
