Has the CME arrived yet (Oct 30, 2021)? |

The ACE satellite sits 1.4M km sunward from Earth, measuring the solar wind speed. You can see the data here: ACE SWEPAM DATA. The yellow trace shows the current solar wind speed and when this rapidly increases well above 400 km/s then the CME is 15 minutes away! |
