SDF Number 37 Issued at 2200Z on 06 Feb 2018
IA. Analysis of Solar Active Regions and Activity from 05/2100Z to
06/2100Z: 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
06/1858Z from Region 2699 (S08E51). There are currently 1 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares on day one (07 Feb) and expected to
be very low with a slight chance for a C-class flare on days two and
three (08 Feb, 09 Feb).
IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 465 km/s at 06/1518Z. Total IMF reached 7 nT at
06/0101Z. The maximum southward component of Bz reached -4 nT at
06/0942Z.
