:Product: Weekly Highlights and Forecasts
:Issued: 2016 Nov 14 0648 UTC # Prepared by the US Dept. of Commerce, NOAA, Space Weather Prediction Center # Product description and SWPC contact on the Web # http://www.swpc.noaa.gov/weekly.html # # Weekly Highlights and Forecasts # Highlights of Solar and Geomagnetic Activity 07 - 13 November 2016 Solar activity was very low through the period with only a few low-level B-class flares observed from Regions 2605 (N07, L=191, class/area Cro/030 on 31 October), 2607 (S17, L=143, class/area Dai/100 on 11 November), and 2610 (N15, L=022, class/area Cro/030 on 12 November). No Earth-directed coronal mass ejections (CME) were observed in available satellite imagery during the reporting period. No proton events were observed at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels on 09, and 11-12 November and high levels on 07-08, 10, and 13 November. The maximum flux of 10,253 pfu was observed at 13/1825 UTC. Geomagnetic field activity was at quiet to active levels with an isolated period of G1 (Minor) storming reported during the 11/0000-0300 UTC synoptic period in response to a negative polarity coronal hole high speed stream. Solar wind speed increased steadily from background levels near 300 km/s to a peak of 767 km/s towards the end of the period. Total field ranged between 3 and 16 nT while the Bz component reached a maximum southward deviation of -11 nT. The geomagnetic field was at mostly quiet levels on 07-09 November, quiet to active levels on 10 and 12-13 November, and quiet to G1 (Minor) levels on 11 November. Forecast of Solar and Geomagnetic Activity 14 November - 10 December 2016 Solar activity is expected to be at very low levels with a slight chance for C-class flares over the forecast period. No proton events are expected at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal to moderate levels with high levels likely on 14-19, 22 November - 05 December, 07 and 10 December due to recurrent CH HSS influence. Geomagnetic field activity is expected to be at unsettled to active levels on 14-15, 19-29 November, and 07-10 December with G1 (Minor) geomagnetic storm levels likely on 21-23 and 25 November, G2 (Moderate) levels likely on 21-22 November, and G3 (Strong) levels likely on 21 November due to recurrent CH HSS effects. |
