Solar activity has been very low today (23 March, UT). As anticipated,
the effect of the coronal hole is continuing to keep the solar wind
stream strong. Very Low levels of solar activity are expected for the
next 3 days (24 to 26 March) with a slight chance of C-class activity.
Although isolated periods of minor storm were observed on high
latitudes, geomagnetic activity did not rise to the expected levels as
the north-south component of IMF, Bz did not stay south during most
parts of the UT day (23 March). Due to the continued effect of the
coronal hole, geomagnetic activity may rise up to active levels with a
slight possibility of isolated minor storm periods in Aus/NZ regions
on 24 March. Geomagnetic activity in this region is then expected to
gradually decrease to unsettled and then to quiet levels through the
days 25 and 26 March. MUFs were mostly near predicted monthly values
today (23 March, UT) with some periods of minor enhancements. Minor to
mild MUF depressions and degradations in HF conditions are expected on
24 March due to expected continued rise in geomagnetic activity levels
on this day. HF conditions are expected to stay mostly at normal
levels on 25 and 26 March.
