Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Jun 02 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was at low levels. Region 2661 (N05E60, Dao/beta) produced the strongest flare of the period, a C3 at 01/2259 UTC. The region developed slightly more area over the reporting period. No Earth-directed CMEs were observed during the reporting period.

Forecast: Solar activity is likely to be at low levels over the next three days (02-04 Jun) with a slight chance for M-class (R1-R2/Minor-Moderate) flares.

Energetic Particle

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

Forecast: The greater than 2 MeV electron flux is expected to continue at moderate levels throughout the period (02-04 Jun) with a chance for high levels on days one and three (02, 04 Jun). 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 DSCOVR spacecraft, reflected a weak disturbance at the beginning of the period which gradually transitioned towards nominal conditions by the periods end. Total magnetic field strength slowly declined from a peak of around 9 nT at the beginning of the period to around 3 nT by the periods end. The Bz component was predominantly positive until after 01/2230 UTC, when a predominantly negative trend was observed. Solar wind speeds were mostly between 350-400 km/s with an enhancement to 400-450 km/s between roughly 01/1900-02/0100 UTC. Phi exhibited a slow transitions from the positive sector to the negative sector between 01/1600-2230 UTC.

Forecast: Solar wind parameters are expected to be slightly enhanced over the next three days (02-04 Jun) due to the anticipated influence of a positive polarity CH HSS and the possible arrival of a CME from 30 May on day two (03 Jun).

Geospace

24 hr Summary: The geomagnetic field was quiet to unsettled.

Forecast: The geomagnetic field is expected to be quiet to unsettled over the next three days (02-04 Jun) with active conditions expected on day two (03 Jun) due to the influence of a positive polarity CH HSS and the possible arrival of the 30 May CME.
