COMMENT: HF conditions were Normal with some nighttime depressions
at low latitudes in the north due to prevailing neutral wind
and electric field conditions in the equatorial anomaly. Expect
similar conditions for 10-11 August. A high speed solar wind
stream from a coronal hole should be effective 12 Aug, causing
Unsettled geomagnetic conditions, possibly translating to slightly more
suppressed MUFs.
