Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 137 Issued at 2200Z on 17 May 2015
IA. Analysis of Solar Active Regions and Activity from 16/2100Z to
17/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 6 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares and a slight chance for an M-class
flare 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 levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 428 km/s at
17/0716Z. Total IMF reached 8 nT at 17/2057Z. The maximum southward
component of Bz reached -5 nT at 17/1617Z. Electrons greater than 2 MeV
at geosynchronous orbit reached a peak level of 9241 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on days one and two (18 May, 19 May) and
quiet levels on day three (20 May).
