Coronal mass ejection arrival
The X8.2 coronal mass ejection has arrived. A weak impact was observed at 19:29 UTC with a minor increase in the solar speed, density and the total strength of the interplanetary field (Bt). This is without a doubt the glancing blow arrival of the X8.2 coronal mass ejection as the low energy protons measured by ACE/EPAM peaked at the moment of impact, a classic sign of a CME arrival.
