Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 136 Issued at 2200Z on 16 May 2015
IA. Analysis of Solar Active Regions and Activity from 15/2100Z to
16/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
15/2329Z from Region 2339 (N12W59). There are currently 7 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low with
a slight chance for an M-class flare on days one and two (17 May, 18
May) and expected to be very low with a chance for a C-class flares on
day three (19 May).
IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: 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 518 km/s at
16/0033Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 11005 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to minor storm levels on day one (17 May), quiet to
active levels on day two (18 May) and unsettled levels on day three (19
May).
