Solar activity was moderate. Region 1195 (S18E28) produced two M-class flares: an M1/Sn at 0457Z and an M1/1n at 1553Z. There was not any indication of a CME associated with either of these events. Region 1195 dominated the activity during the past 24 hours and produced numerous additional C-class x-ray events. The group showed steady growth throughout the period and is currently estimated to have 370 millionths sunspot area. The group also shows some magnetic complexity (Beta-Gamma); particularly interesting is an east-west section of the inversion line in the center of the group which has a favorable configuration for building shear. Region 1193 (N17W45) is gradually decaying and did not produce any flares.

Solar activity is expected to be moderate for the next three days. Additional M-class flares are likely from Region 1195, especially if it continues to grow.

The geomagnetic field was generally quiet during the past 24 hours.

The geomagnetic field is expected to be quiet for the next three days (23-25 April).
