Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 120 Issued at 2200Z on 30 Apr 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 is currently 1 numbered sunspot region on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
with a slight chance for a C-class flare on days one, two, and three (01
May, 02 May, 03 May).
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 397 km/s at
30/2021Z. Total IMF reached 11 nT at 30/0826Z. The maximum southward
component of Bz reached -8 nT at 30/1640Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (01 May) and quiet levels
on days two and three (02 May, 03 May).
