23 Feb    70    Normal-fair      Near predicted monthly values/depressed

COMMENT: MUFs depressions up to nearly 20% were observed on many 
locations today. Periods of near predicted monthly values and 
enhancements by about 15% were also observed, mainly on low and 
mid latitudes. Mostly normal to fair HF conditions on low and 
mid latitudes and fair to poor on high latitudes may be expected 
on 23 and 24 February due to expected rise in geomagnetic activity 
levels on these days. HF conditions may return to mostly normal 
levels on 25 February.
