Solar activity was very low. Only weak B-class activity was observed. Three new regions were numbered during the period. Regions 1065 (S32W16) and 1066 (S27E16) formed on the disk as single, unipolar spot groups. Region 1067 (N23E56) rotated on the disk as a bi-polar spot group.

Solar activity is expected to be very low to low. C-class activity is likely from Region 1067.

The geomagnetic field ranged from quiet to major storm levels during the period. Activity was quiet through about 1100Z when levels increased to active to minor storming at middle latitudes, with major storm periods observed at high latitudes. At about 0900Z, observations from the ACE spacecraft indicated increases in temperature, density and wind velocity, while the Bz component of the interplanetary magnetic field showed strong negative incursions to -20 nT. Wind speeds gradually increased from about 375 km/s to near 700 km/s by 1645Z. Thereafter, wind speeds leveled out to about 650 km/s, and remained so through the balance of the period. These signatures were indicative of a co-rotating interaction region in advance of a recurrent coronal hole high speed wind stream.

The geomagnetic field is expected to be at unsettled to active levels, with isolated minor storm periods at middle latitudes for days one and two (03 - 04 May). During the same period, high latitudes should expect similar conditions with isolated major storm periods. This activity is due to a geoeffective, recurrent coronal hole high speed wind stream. By day three (05 May), activity is expected to decrease to mostly quiet to unsettled levels with isolated active periods at middle latitudes, while high latitudes could see isolated minor storm periods.
