Additional Comments

Solar wind has now returned to background levels and overall low geomagnetic activity is expected.
Several coronal mass ejections (CMEs) were observed between 03-04 Aug, most of which are not believed to be fully Earth-directed. However, possible glancing impacts can be anticipated on 07-08 Aug, increasing the chances of ACTIVE and STORM G1 intervals.
