Solar activity remained at low levels. Region 1178 (S17W36) produced a C1/Sf at 31/2221Z associated with a partial-halo CME that appeared to be directed southward, out of the ecliptic plane. Region 1178 decayed to a plage area during the period. Region 1176 (S16W65) produced C3 flares at 01/0156Z and 01/0354Z, each of which were associated with CME activity. This CME activity also appeared to be directed southward, out of the ecliptic plane. Region 1176 gradually decayed during the period with a loss of spot count and area. It was classified as an Fso-type with a simple beta magnetic configuration. Region 1183 (N17E01) showed a gradual increase in spot count and area and was classified as an Esi-type with a beta magnetic configuration. New Region 1184, a single-spot Axx-type, was numbered.

Solar activity is expected to be low during the period (02 - 04 April) with a slight chance for moderate activity (isolated M-class).

Geomagnetic activity increased to quiet to active levels. ACE solar wind observations indicated the onset of a coronal hole high-speed stream (CH HSS) at approximately 01/1600Z. Velocities increased to a peak of 495 km/s at 01/1801Z. IMF changes associated with the CH HSS included increased Bt (peaks to 12 nT during 01/2000 - 2100Z) and intervals of southward Bz (maximum deflection -10 nT at 01/1628Z).

Geomagnetic activity is expected to be at quiet to unsettled levels during day 1 (02 April) with a chance for active levels as CH HSS effects persist. Activity is expected to decrease to mostly quiet levels during days 2 - 3 (03 - 04 April) as CH HSS effects subside.
