Additional Comments

Solar wind speed is starting to reach elevated levels due to the ongoing coronal hole high-speed stream.
Coronal mass ejections (CMEs) associated with a filament eruption on 06-May and an M-class flare observed around 15:00 UT on 07-May are not expected to be fully Earth-directed, however glancing impact cannot be ruled out.
Enhanced geomagnetic conditions are anticipated over the weekend, with increased chances of STORM G1 intervals.
