COMMENT: Weak ionosphere for the Antarctic region with increased 
absorption. The present proton event is declining. HF propagation 
conditions are expected to improve slightly over the next 2 days. 
Degraded ionospheric conditions possible day 3 affecting higher 
latitudes due to anticipated geomagnetic disturbances.
