:Product: 0629RSGA.txt :Issued: 2015 Jun 29 2200 UTC # Prepared jointly by the U.S. Dept. of Commerce, NOAA, # Space Weather Prediction Center and the U.S. Air Force. # Joint USAF/NOAA Solar Geophysical Activity Report and Forecast SDF Number 180 Issued at 2200Z on 29 Jun 2015 IA. 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. The largest solar event of the period was a C2 event observed at 29/1807Z from Region 2373 (N15E55). There are currently 3 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a slight chance for an M-class flare 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, as measured by the ACE spacecraft, reached a peak speed of 464 km/s at 29/1052Z. Total IMF reached 8 nT at 29/0730Z. The maximum southward component of Bz reached -5 nT at 29/0622Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 5 pfu at 29/0240Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 7557 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one and three (30 Jun, 02 Jul) and quiet to unsettled levels on day two (01 Jul). III.
