Solar Activity

.24 hr Summary...
Solar activity was at low levels due to occasional C-class flares.
Region 2644 (N12E11, Dki/beta-gamma) exhibited consolidation in its
leader spots, but separation between the leader and trailer spots. This
region was responsible for several B-class and a few C-class flares
during the period. Region 2645 (S09E51, Dao/beta) continued to show
signs of growth in both areal coverage and magnetic complexity. It was
responsible for occasional C-class flares, to include the largest flare
of the period, a C5/Sf at 27/1820 UTC. Region 2646 (N07W67, Axx/alpha)
decayed to a single spot during the period and was inactive.

A couple of narrow CMEs were observed in SOHO/LASCO-C2 imagery ejecting
off the eastern side of the solar disk. Analysis of the CMEs indicated
that both appeared to be on a more eastern trajectory and are not
expected to have an Earth-directed component.

.Forecast...
Solar activity is expected to be very low, with C-class flares likely,
and a slight chance of M-class flares (R1-R2, Minor-Moderate) the next
three days (28-30 Mar) due to the instability and magnetic complexity of
Regions 2644 and 2645.
