Solar activity report
Report of Solar-Geophysical Activity 2023 Jul 02 2200 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 183 Issued at 2200Z on 02 Jul 2023IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M2 event observed at
02/0235Z from Region 3359 (S22E41). There are currently 7 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be moderate
with a slight chance for an X-class flare on days one, two, and three
(03 Jul, 04 Jul, 05 Jul).
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 510 km/s at 02/0402Z. Total IMF reached 6 nT at
02/1729Z. The maximum southward component of Bz reached -4 nT at
02/0840Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 2201 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on day one (03 Jul) and quiet to unsettled levels
on days two and three (04 Jul, 05 Jul). Protons have a slight chance of
crossing threshold on days one, two, and three (03 Jul, 04 Jul, 05 Jul).
