Solar activity is expected to be at the R1 level on UT day 18-Aug,
with a chance of R2. The solar wind speed is expected to be moderate
to strong. G0-G1 geomagnetic conditions are expected, with a chance of
G2 due to the combined effects of a coronal hole high speed wind
stream and the expected arrival of three CMEs first observed on 14-Aug
and 15-Aug. Degraded HF conditions are possible for middle to high
latitudes. Shortwave fadeouts are possible.
