Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C3 event observed at 01/2233Z. There are currently 12 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with a chance for M-class flares on days one, two, and three (03 Jul, 04 Jul, 05 Jul).
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 449 km/s at 01/2101Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 641 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to minor storm levels on day one (03 Jul), quiet to active levels on day two (04 Jul) and quiet to unsettled levels on day three (05 Jul).
