CME watch, coronal hole stream incoming
We are currently awaiting the possible arrival of a glancing blow coronal mass ejection passage related to an M2.4 solar flare from 9 February. The coronal mass ejection was expected to arrive early this morning but there are no signs in the solar wind data that suggest that the coronal mass ejection has arrived. The low energy protons as measured by ACE EPAM are slightly elevated which could suggest that the coronal mass ejection has yet to come. Any impact (if any) will likely be minor and it is unlikely that it can cause a geomagnetic storm but you should nonetheless be alert in the coming hours for a possible impact.
