Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 86 Issued at 2200Z on 27 Mar 2015
IA. Analysis of Solar Active Regions and Activity from 26/2100Z to
27/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
27/1509Z from Region 2309 (N14W79). There are currently 8 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (28 Mar, 29 Mar,
30 Mar).
IIA. Geophysical Activity Summary 26/2100Z to 27/2100Z: 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
465 km/s at 26/2152Z. Total IMF reached 7 nT at 27/1817Z. The maximum
southward component of Bz reached -5 nT at 27/0354Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 4691 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at active to minor storm levels on days one and two (28 Mar, 29
Mar) and quiet to active levels on day three (30 Mar).
