Here is the current forecast discussion on space weather and geophysical activity, issued 2016 Jul 06 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Region 2559 returned to plage after losing its spots. Region 2560 (S08E48, Axx/alpha) remained unremarkable and was absent of significant flare activity. The CME mentioned in the previous discussion product which lifted off of the northwest limb and was first observed in LASCO C2 imagery at 05/2117 UTC was deemed to not contain an Earth-directed component. There were no geoeffective CMEs observed in available satellite imagery during the reporting period.

Forecast: Solar activity is expected to be very low throughout the forecast period (06-08 Jul).

Energetic Particles

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 throughout the period.

Forecast: The greater than 2 MeV electron flux is expected to be at normal to moderate levels throughout the forecast period (06-08 Jul). The greater than 10 MeV proton flux is expected to persist at background levels throughout the forecast period.

Solar Wind

24 hr Summary: Solar wind parameters, as measured by the ACE spacecraft, reflected background conditions. Total magnetic field strength was between 3 and 5 nT. Wind speed steadily decreased from 360 km/s to around 320 km/s by periods end. Phi angle was oriented in a negative (towards) sector.

Forecast: The solar wind environment is expected to continue at background levels for the remainder of day one (06 Jul). Day two (07 Jul) is likely to see an enhancement in total IMF strength due to CIR effects, followed by an increase in solar wind speed due to the onset of a positive polarity CH HSS. The enhanced solar wind environment is expected to continue into day three (08 Jul).

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be quiet for the remainder of day one (06 Jul). Day two (07 Jul) is expected to experience unsettled to active levels of response, with a likely period of G1 (Minor) geomagnetic storming later in the day due to CIR and CH HSS effects. Unsettled to active conditions are expected on day three (08 Jul) as CH HSS influences persist.
