Solar flare activity was very low during 30 Mar UT and it is expected
to remain very low during the next 2 days. Active Region (AR) 2526 is
the only significant sunspot group visible on the solar disk. Coronal
Hole (CH) 725 is located near the equator and is rotating through the
Western Hemisphere. The frontal disturbance ahead of fast wind
emanating from this coronal hole drove a minor geomagnetic storm
during the previous solar rotation. There is a possibility of a repeat
performance during 2-3 Apr. Conditions will likely reach the G1 level,
possibly the G2 level briefly. The solar wind speed trended downward
during 30 Mar and is presently about 500 km/s. Geomagnetic conditions
are expected to be mostly quiet with unsettled intervals for most of
31 Mar and 1 Apr. Conditions for HF radio wave propagation were mildly
depressed in the Northern Hemisphere and near predicted monthly values
in the Australian region.
