COMMENT: Nearly normal HF conditions were observed today
with isolated periods of minor MUF depressions on low and
high latitudes. Due to continued Very Low levels of solar
activity less ionising radiation is being received. Nearly
similar HF conditions may be expected for the next 3 days.
Periods of partial to complete blanketing by Sporadic E-layer
were observed at some low and mid latitude locations today.
Similar effect of Sporadic E-layer may continue to be observed
over the next few days.
