What appears to be a shock passage was just detected by the ACE spacecraft at 09:56 UTC (June 13). This is likely the CME observed leaving the Sun on 6/11 arriving a little later than predicted. The solar wind speed increased from around 570 km/s to currently near 650 km/s.

A solar flare measuring M9.3 was detected around Earth facing sunspot region 4455 peaking at 01:36 UTC (June 3). A further update will be provided if a CME is associated with this event. So far it appears that an eruption with this event would likely be minor. More to follow.

Impressive CME produced by X2.5 flare on Friday morning is heading mostly away from Earth. Extreme edge of CME may pass close to Earth in days ahead, however no major impacts should be expected. SolarHam.com
