Additional Comments

The solar wind speed has now returned to ambient levels. Geomagnetic activity expected to remain QUIET until the latter part of the second forecast interval when we should start to see some influence from the next coronal hole high speed stream. On arrival, ACTIVE periods are likely with a chance of STORM G1 possible.
