COMMENT: Maximum usable frequencies (MUFs) in the Australian
region on UT day 5-Feb were 15-30% enhanced. Sporadic E was observed
throughout the Australian region. MUFs are expected to be near
predicted monthly values to 15% enhanced over 6-8 Feb, with a
chance of depressions over 6-8 Feb due to possible geomagnetic
activity caused by a group of equatorial coronal holes currently
in a geoeffective position and possible glancing impacts from
CMEs first observed on 3-Feb and 4-Feb. Sporadic E is possible
during local night, affecting lower frequencies.
