COMMENT: Periods of minor to significant MUF enhancements as

today. Minor to significant degradations in HF conditions and 
depressions in MUFs may be expected on 1 January due to expected 
continued rise in geomagnetic activity levels on this day. HF 
conditions in the region may be expected to improve through 2 
and 3 January.
