Joint USAF/NOAA Solar Geophysical Activity Report and Forecast SDF Number 157 Issued at 2200Z onIA. Analysis of Solar Active Regions and Activity from 05/2100Z to 06/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C1 event observed at 06/1100Z from Region 2712 (N14, L=179). There are currently 0 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low on days one, two, and three (07 Jun, 08 Jun, 09 Jun). IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 462 km/s at 06/1655Z. Total IMF reached 9 nT at 06/2100Z. The maximum southward component of Bz reached -7 nT at 06/1822Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 19491 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one () and quiet levels on days two and three (08 Jun, 09 Jun). III.
