Additional Comments

A coronal hole high speed stream is expected to become geoeffective during the first forecast interval, and is likely to continue to disturb the solar wind for a few days. A coronal mass ejection (CME), associated with an M-class solar flare, which left the Sun on 25th May could also hit the Earth with a glancing blow early on 28th May. Periods of ACTIVE geomagnetic conditions are likely throughout the three forecast intervals, with STORM G1 periods possible, particularly if the CME does arrive.
