Analysis of Solar Active Regions and Activity from 10/2100Z to
11/2100Z: Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M2 event observed at
11/1526Z. There are currently 9 numbered sunspot regions on the disk.
Solar Activity Forecast: Solar activity is expected to be moderate
with a chance for X-class flares on days one, two, and three (12 Sep, 13
Sep, 14 Sep).
Geophysical Activity Summary 10/2100Z to 11/2100Z: 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
404 km/s at 11/0248Z. Total IMF reached 9 nT at 10/2252Z. The maximum
southward component of Bz reached -7 nT at 11/0356Z. Protons greater
than 10 MeV at geosynchronous orbit reached a peak level of 28 pfu at
11/0515Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 154 pfu.
Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to major storm levels on day one (12 Sep), active to
severe storm levels on day two (13 Sep) and unsettled to minor storm
levels on day three (14 Sep). Protons are expected to cross threshold on
days one and two (12 Sep, 13 Sep) and are expected to cross threshold on
day three (14 Sep).
