Additional Comments

A small coronal hole high speed stream may impact the Earth later during the first forecast period. This combined with the possible glance from a small CME may lift geomagnetic conditions to ACTIVE.
A larger more southerly coronal hole is likely to elevate solar winds again in the third period, again leading to ACTIVE possibly STORM G1 spells.
