Analysis of Solar Active Regions and Activity from 15/2100Z to
16/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C4 event observed at
16/1924Z from Region 1748 (N12E36). There are currently 10 numbered
sunspot regions on the disk.
Solar Activity Forecast: Solar activity is expected to be high with
a chance for X-class flares on days one, two, and three (17 May, 18 May,
Geophysical Activity Summary 15/2100Z to 16/2100Z: 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
450 km/s at 15/2326Z. Total IMF reached 7 nT at 15/2115Z. The maximum
southward component of Bz reached -6 nT at 16/0139Z. Protons greater
than 10 MeV at geosynchronous orbit reached a peak level of 32 pfu at
16/0410Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 117 pfu.
Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (17 May) and quiet to
unsettled levels on days two and three (18 May, 19 May). Protons are
expected to cross threshold on day one (17 May), are expected to cross
threshold on day two (18 May) and are expected to cross threshold on day
three (19 May).
