According to the report of Space Weather Prediction Center (NOAA), posted on Sunday and collaborative work of USAF/NOAA Solar Geophysical Activity Report and Forecast SDF Number 249 Issued at 2200Z (September 6, 2015).

AI. Analysis show that Solar activity has been at very low levels for the past 24 hours. There are currently 3 numbered sunspot regions on the disk.

IB. Solar Activity Forecast: Solar activity is expected to be very low with a slight chance for a C-class flare on days one, two, and three (07 Sep, 08 Sep, 09 Sep).

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, as measured by the ACE spacecraft, reached a peak speed of 557 km/s at 06/1507Z. Total IMF reached 9 nT at 06/0826Z. The maximum southward component of Bz reached -7 nT at 06/0807Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1973 pfu.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (07 Sep), quiet to unsettled levels on day two (08 Sep) and quiet levels on day three (09 Sep).
