Here is the current forecast discussion on space weather and geophysical activity, issued 2015 Nov 15 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low with no reportable events observed this period. All four spotted regions were quiet and stable as was the remainder of the disk and limb. No Earth-directed coronal mass ejections (CMEs) were observed in available coronagraph imagery. Forecast: Solar activity is expected to be very low with a chance for C-class flares over the next three days (15-17 Nov).

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux reached high levels with a peak flux of 2,730 pfu observed at 14/1415 UTC. 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 reach high levels over the next three days (15-17 Nov) while 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 were indicative of waning coronal hole high speed stream (CH HSS) influence and the transition to a background solar wind environment. Solar wind speeds began the period near 475 km/s and steadily decreased to end-of-period speeds at about 390 km/s. IMF total field strength values ranged between 1-7 nT while the Bz component did not vary much beyond +/-5 nT. The phi angle began the period in a negative (toward) solar sector when it transitioned to a positive (away) solar sector orientation after 14/2040 UTC.

Forecast: Solar wind parameters are expected to remain at background levels over the next three days (15-17 Nov) under a nominal solar wind regime.

Geospace

24 hr Summary: The geomagnetic field was at quiet to unsettled levels throughout the period due to waning CH HSS influence and the return to a background solar wind environment.

Forecast: The geomagnetic field is expected to be at quiet to unsettled levels over the next three days (15-17 Nov) under a nominal solar wind regime.
