Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 181 Issued at 2200Z on 30 Jun 2018

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 0 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (01 Jul, 02 Jul, 03 Jul).

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
reached a peak of 496 km/s at 30/1843Z. Total IMF reached 5 nT at
30/1137Z. The maximum southward component of Bz reached -3 nT at
30/0719Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 5197 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (01 Jul, 02 Jul)
and quiet levels on day three (03 Jul).
