Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 150 Issued at 2200Z on 30 May 2015

IA.  Analysis of Solar Active Regions and Activity from 29/2100Z to
30/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 2 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 (31 May,
01 Jun, 02 Jun).

IIA.  Geophysical Activity Summary 29/2100Z to 30/2100Z: 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 482 km/s at
29/2133Z. Total IMF reached 6 nT at 30/0208Z. The maximum southward
component of Bz reached -5 nT at 30/1044Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (31 May, 01 Jun, 02
Jun).
