Additional Comments

Increase in geomagnetic activity is expected during the first two forecast periods due to the anticipated arrival of the coronal mass ejection (CME) observed on the 28th June. The high speed stream from a southern coronal hole could combine with the CME resulting in a stronger impact, with geomagnetic conditions reaching up to STORM G2 levels.
