Analysis of Solar Active Regions and Activity from 28/2100Z to 29/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 10 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 (30 Jun, 01 Jul, 02 Jul). IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 697 km/s at 29/0652Z. Total IMF reached 5 nT at 29/1824Z. The maximum southward component of Bz reached -4 nT at 29/1629Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 6349 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one and two (30 Jun, 01 Jul) and quiet to active levels on day three (02 Jul). III.
