COMMENT: The HF propagation conditions were mostly normal at 
mid latitudes during UT day, 27 March, Moderate f0F2 depressions 
were noted at Cocos and Niue stations. f0F2 depressions were 
also observed as high latitudes due to minor geomagnetic activity 
associated with high speed solar wind stream. Expect mild to 
moderate depressions for MUFs at mid to high latitudes due to 
increase in the geomagnetic activity over the next 48 hours.
