COMMENT: Mostly normal HF conditions were observed on most 
locations during the UT day today with periods of minor to 
moderate depressions at some low and mid latitude locations. 
Minor to moderate MUF depressions and degradations in HF 
conditions may be expected for the next 3 days as geomagnetic 
activity may rise during this period due to coronal hole effect.
