Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 170 Issued at 2200Z on 19 Jun 2015
IA. Analysis of Solar Active Regions and Activity from 18/2100Z to
19/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C8 event observed at
19/0927Z from Region 2371 (N13E27). There are currently 2 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be moderate
with a slight chance for an X-class flare on days one, two, and three
(20 Jun, 21 Jun, 22 Jun).
IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
444 km/s at 18/2115Z. Total IMF reached 5 nT at 19/1148Z. The maximum
southward component of Bz reached -4 nT at 19/0948Z. Protons greater
than 10 MeV at geosynchronous orbit reached a peak level of 12 pfu at
18/2125Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1057 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (20 Jun), quiet to unsettled levels on
day two (21 Jun) and quiet to minor storm levels on day three (22 Jun).
Protons have a chance of crossing threshold on days one, two, and three
(20 Jun, 21 Jun, 22 Jun).
