CME INBOUND
A CME is headed for Earth.
Launched Oct 6, 06:23 UT at 570 km/s.
Expected around Oct 9, 12:42 UT in 1 d 12 h
80% window: Oct 8, 16:44 UT to Oct 10, 09:56 UT.
If it arrives: most likely Kp 4.4 (below storm level), up to Kp 6.4 (G2 moderate) if its magnetic field points south. Nobody can know that until about an hour before it arrives.
2 more Earth-directed CMEs are behind it.
