Solar activity was moderate. A gradual rise in X-rays began at around 04/1000Z and continued through the end of this period. Since 04/1500Z, the X-ray baseline ranged from C4 - C8 with occasional fluctuations to the M1 level. Development within regions near the SE limb, the SW limb and within Region 9601 (N13W22) are the likely sources of the enhanced X-rays. Region 9606 (S17E45) produced an impulsive M1/1n at 04/2017Z. Region 9601, at almost 800 millionths of white light area is moderately complex and the largest region on the visible disk. Several plage fluctuations were observed in this region, but only minor C-class flareS were observed. The two M-class flares observed yesterday at 03/1545Z and 03/1841Z were likely associated with CMEs off the SE limb. New region 9607 (S16E68) was numbered today.

Solar activity is expected to be at moderate to high levels. New regions near the SE limb and developing regions near the SW limb have potential for isolated M-class flares. Region 9601 also has potential for M-class flares.

The geomagnetic field was mostly at unsettled to active levels. A high speed coronal hole stream and possibly some weak CME effects are producing the disturbed conditions.

The geomagnetic field is expected to return to quiet to unsettled conditions by the end of day one and persist through days two and three.
