Additional Comments

Overall low geomagnetic activity this weekend is expected to become slightly elevated, with chances of ACTIVE and brief STORM G1 intervals, due to the anticipated glancing effects from coronal mass ejections (CMEs) observed on 03-04 Aug.
A high speed stream from a small coronal hole might cause some further minor enhancements in geomagnetic activity.
