Solar activity was at low levels. Only isolated B-class and low-level C-class events were observed during the period, all from Region 1176 (S16E30). The region grew in area and spot count, mostly from new development just to the NNE of the large leader spot. Both Regions 1177 (N21E24) and 1178 (S15E55) developed penumbra in their leader spots and were classified as bi-polar C-type groups. Two new regions rotated on the disk during the period; Region 1180 (N26E66) and Region 1181 (S23E69), both H-type groups. A partial Halo CME was first observed at 24/1203Z in LASCO C3 imagery extending through the northern hemisphere of the solar disk. The likely source was from the M1/1f flare from Region 1176 at 24/1207Z.

Solar activity is expected to be low for the next three days (26 - 28 March) with a chance for M-class activity, primarily from Region 1176.

The geomagnetic field was quiet. ACE solar wind data indicated a gradual decrease in velocities from a high of near 500 km/s at 24/2304Z to a low of about 400 km/s at 25/1438Z. During the period, IMF Bz was variable between +5 nT and -4 nT.

The geomagnetic field is expected to be at predominately quiet levels for the days one and two (26 - 27 March). By day three (28 March), quiet to unsettled conditions, with isolated active periods, are possible due to effects from the 24 March CME.
