COMMENT: MUFs were mostly near monthly predicted values over
the last 24 hours, with significant enhancements seen at Cocos
Island. Some depressed conditions are expected over the next
2 days due to geomagnetic activity. This is expected to depress
the MUFs by up to 20% for southern regions. Central regions may
experience some depressions and northern Australia should be
around predicted monthly values. Current conditions do not yet
show significant depressions. The situation will be monitored
and an IPS HF warning issued if MUFs become significantly degraded
over the next 24 hours.
