Solar activity has been very low today (20 March, UT). The effect of a
coronal hole is expected to strengthen the solar wind stream from late
in the UT day 21 March. Very Low levels of solar activity are expected
for the next 3 days (21 to 23 March). Quiet geomagnetic conditions
were observed today. Due to the coronal hole effect, geomagnetic
activity may rise to unsettled levels on 21 March, to active levels on
22 March and to minor storm levels on 23 March. MUFs were mostly near
predicted monthly values today. MUFs and HF conditions are expected to
stay mostly normal on 21 March. Minor to moderate MUF depressions and
degradations in HF conditions are possible on 22 and 23 March due to
expected rise in geomagnetic activity levels on these days.
