Solar Activity

» 24 hr Summary: Solar activity was very low. All numbered active regions on the visible disk were either stable or in decay. No Earth-directed CMEs were observed in available coronagraph imagery.

» Forecast: Solar activity is expected to reach low levels with a slight chance for R1-R2 (Minor-Moderate) radio blackouts over 05-07 Jul.

Energetic Particle

» 24 hr Summary: The greater than 2 MeV electron flux was at normal to moderate levels. The greater than 10 MeV proton flux was at background levels.

» Forecast: The greater than 2 MeV electron flux is expected to continue at normal to moderate levels over 05-07 Jul. The greater than 10 MeV proton flux is expected to persist at background levels through 07 Jul.

Solar Wind

» 24 hr Summary: Solar wind parameters reflected the onset of negative polarity coronal hole influence during the period. The total magnetic field strength varied between 8-13 nT, and the Bz component reached as far south as -10 nT. Solar wind speeds steadily increased from a low of 330 km/s early in the period to a peak of around 480 km/s.

» Forecast: Solar wind parameters are expected to remain mildly elevated over 05-07 Jul due to negative polarity coronal hole influence.

Geospace

» 24 hr Summary: The geomagnetic field reached active levels in response to negative polarity coronal hole influence.

» Forecast: The geomagnetic field is expected to reach active levels on 05 Jul, with quiet to unsettled levels expected over 06-07 Jul, due to negative polarity coronal hole influence.
