Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Jul 03 1230 UTC.

Solar Activity

24 hr Summary: Solar activity remained at very low levels. Region 2664 (N18, L=313) produced multiple B-class flares, including a B8/Sf flare at 03/0637 UTC, after rotating around the west limb. There were no Earth-directed CMEs observed in available satellite imagery.

Forecast: Solar activity is expected to continue at very low levels over the next three days (03-05 Jul).

Energetic Particles

24 hr Summary: The greater than 2 MeV electron flux was at normal levels and the greater than 10 MeV proton flux remained at background values.

Forecast: The greater than 2 MeV electron flux is expected to be at normal to moderate levels over the next three days (03-05 Jul) and the greater than 10 MeV proton flux is expected to remain at background levels.

Solar Wind

24 hr Summary: Solar wind parameters, as measured by the DSCOVR spacecraft, reflected waning transient enhancements. Solar wind speeds showed a decreasing trend with a reported high value of 551 km/s at 02/1438 UTC and end of period values near 420 km/s. Total field strength also showed a decreasing trend, beginning the period near 9 nT and ending at approximately 2 nT. The Bz component was predominantly north with slight southward deviation to a low of -4 nT. Phi angle was oriented in a positive solar sector until approximately 03/0200 UTC when it began a gradual transition into negative territory.

Forecast: Enhancements in the solar wind are expected to continue through day one (03 Jul) from the passage of the 28 Jun CME. Day two and three (04-05 Jul) will likely transition into weak enhancements from a small, negative polarity CH HSS.

Geospace

24 hr Summary: The geomagnetic field was at quiet to active levels due to persistent CME effects.

Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (03 Jul) with a chance for G1 (Minor) storm levels due to waning influence from the 28 Jun CME. A return to mostly quiet to unsettled conditions is expected on days two and three (04-05 Jul) as diminishing CME effects transition to the weak influence of a small, negative polarity CH HSS.
