Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 142 Issued at 2200Z on 22 May 2015
IA. Analysis of Solar Active Regions and Activity from 21/2100Z to
22/2100Z: 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 on days one, two, and three (23 May,
24 May, 25 May).
IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: 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 611 km/s at
22/0332Z. Total IMF reached 5 nT at 22/0705Z. The maximum southward
component of Bz reached -3 nT at 21/2143Z. Electrons greater than 2 MeV
at geosynchronous orbit reached a peak level of 159 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (23 May, 24 May) and quiet to
unsettled levels on day three (25 May).
