SDF Number 118 Issued at 2200Z on 28 Apr 2018
IA. Analysis of Solar Active Regions and Activity from 27/2100Z to
28/2100Z: 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 (29 Apr, 30 Apr, 01 May).
IIA. Geophysical Activity Summary 27/2100Z to 28/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 409 km/s at 28/1625Z. Total IMF reached 6 nT at
27/2332Z. The maximum southward component of Bz reached -2 nT at
28/1303Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 2359 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (29 Apr, 30 Apr, 01
May).
