Here is the current forecast discussion on space weather and geophysical activity, issued 2015 Jul 16 1230 UTC.

Solar Activity

24 hr Summary: Solar activity continued at very low levels. New Region 2387 (N17E68, Cao/beta) rotated around the NE limb and was numbered. The rest of the numbered regions were relatively stable. No Earth-directed coronal mass ejections were observed.

Forecast: Solar activity is expected to be very low with a chance for C-class flares over the next three days (16-18 Jul).

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux was at moderate to high levels levels with a maximum flux of 3160 pfu at 15/1725 UTC. The greater than 10 MeV proton flux remained at background levels throughout the period.

Forecast: The greater than 2 MeV electron flux is expected to be at moderate to high levels for the forecast period (16-18 Jul). The greater than 10 MeV proton flux is expected to remain at background levels (Below S1-Minor).

Solar Wind

24 hr Summary: Solar wind parameters continued to be enhanced with wind speeds ranging from 433 km/s to 620 km/s. Total field was 1 nT and 7 nT while the Bz component fluctuated between +/-5 nT. Phi angle remained predominantly in a positive (away) sector.

Forecast: Solar wind speed is likely to remain enhanced over the next few days (16-18 Jul), however total field is likely to continue at ambient levels.

Geospace

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

Forecast: Quiet to unsettled levels are expected for the forecast period (16-18 Jul).
