Additional Comments

Coronal hole influence is gradualy waning with solar wind speeds on the declining trend. However, isolated ACTIVE periods of geomagnetic activity cannot be ruled out in the first interval. Another coronal hole high speed stream is anticipated to become geo-effective late during the second interval. This will likely lead to ACTIVE geomagnetic conditions with a chance of STORM G1.
