# Daily Space Weather Summary and Forecast.
Analysis of Solar Active Regions and Activity from 17/2100Z to
18/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C6 event observed at
18/0345Z from Region 1748 (N12E11). There are currently 9 numbered
sunspot regions on the disk.
Solar Activity Forecast: Solar activity is likely to be moderate
with a chance for X-class flares on days one, two, and three (19 May, 20
May, 21 May).
Geophysical Activity Summary 17/2100Z to 18/2100Z: The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed, as measured by the ACE spacecraft, reached a peak
speed of 476 km/s at 18/0911Z. Total IMF reached 13 nT at 18/0244Z. The
maximum southward component of Bz reached -13 nT at 18/0146Z. Protons
greater than 10 MeV at geosynchronous orbit reached a peak level of 32
pfu at 17/2245Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 131 pfu.
Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to major storm levels on day one (19 May), quiet to
active levels on day two (20 May) and quiet to unsettled levels on day
three (21 May). Protons are likely to cross threshold on day one (19
May) and have a chance of crossing threshold on days two and three (20
May, 21 May).
