Here is the current forecast discussion on space weather and geophysical activity, issued 2015 Nov 29 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Only mid level B-class flares were observed from Regions 2458 (N08W15, Cao/beta) and 2459 (N04E10, Axx/alpha). The largest was a B6/Sf at 29/0737 UTC from Region 2459. Slight growth was observed in the intermediate spots of Region 2458. The remaining spotted regions were stable. No Earth-directed coronal mass ejections (CMEs) were observed during the period.

Other activity included a full halo CME that was observed in STEREO A COR 2 imagery beginning at 29/0824 UTC. STEREO A EUVI imagery showed a correlated filament eruption on the backside around 29/0755 UTC.

Forecast: Solar activity is expected to be at very low levels with a chance for C-class flares over the next three days (29 Nov-01 Dec).

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux was at normal levels while 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 normal to moderate levels over the next three days (29 Nov-01 Dec). The greater than 10 MeV proton flux is expected to persist at background levels for the forecast period.

Solar Wind

24 hr Summary: Solar wind speed increased from approximately 300 km/s to 415 km/s over the period. Total field continued to be slightly enhanced between 7 nT and 15 nT while the Bz component was mostly north ranging from -10 nt to +13 nT. Phi angle was mostly negative (towards) with minor deviations into a positive (away) sector around mid-day.

Forecast: Nominal conditions are expected through late on day two (29-30 Nov). Late on day two into day three (30 Nov-01 Dec), arrival of a co-rotating interaction region (CIR) and subsequent coronal hole high speed stream (CH HSS) is expected to cause enhancements in the solar wind environment.

Geospace

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

Forecast: The geomagnetic field is expected to be at quiet to unsettled levels through late on day two (29-30 Nov). By late on day two, a positive polarity CH HSS is expected to become geoeffective causing unsettled to active periods. Active to G1 (Minor) storm conditions are expected on day three (01 Dec) due to continued CH HSS effects.
