Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 138 Issued at 2200Z on 17 May 2016
IA. Analysis of Solar Active Regions and Activity from 16/2100Z to
17/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
17/0408Z from just beyond the western limb. There are currently 2
numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be low on days
one and two (18 May, 19 May) and expected to be very low with a chance
for a C-class flares on day three (20 May).
IIA. Geophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 585 km/s at 17/0642Z. Total IMF reached 7
nT at 17/0303Z. The maximum southward component of Bz reached -6 nT at
17/0840Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1372 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (18 May), quiet to active
levels on day two (19 May) and unsettled to minor storm levels on day
three (20 May).
