Solar activity report
Report of Solar-Geophysical Activity 2026 Apr 08 2200 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 98 Issued at 2200Z on 08 Apr 2026IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z Solar activity has been at low levels for the past 24 hours.
There are currently 7 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with
a chance for M-class flares and a slight chance for an X-class flare on
days one and two (09 Apr, 10 Apr) and expected to be low with a chance
for M-class flares on day three (11 Apr).
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 453 km/s at 08/0106Z. Total IMF reached 6
nT at 08/1358Z. The maximum southward component of Bz reached -5 nT at
07/2221Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 7322 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on day one (09 Apr), quiet to minor
storm levels on day two (10 Apr) and active to minor storm levels on day
three (11 Apr). Protons have a slight chance of crossing threshold on
days one, two, and three (09 Apr, 10 Apr, 11 Apr).
