Highlights of Solar and Geomagnetic Activity 14 - 20 November 2016
Solar activity was very low through the period with only a few low-level B-class flares observed from Regions 2610 (N16, L=018, class/area Dao/050 on 17 November), and 2611 (N03, L=291, class/area Cao/020 on 18 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 high levels throughout the period (14-20 November). The maximum flux of 19,442 pfu was observed at 15/1530 UTC.
Geomagnetic field activity was at quiet to unsettled levels on 14-15 November in response to waning influence from a negative polarity coronal hole high speed stream (CH HSS). Solar wind speed steadily decreased from a peak of 681 km/s to period ending values below 400 km/s. Total field ranged between 1 and 7 nT while the Bz component reached a maximum southward deviation of -6 nT. Quiet conditions were observed on 16-20 November under an ambient solar wind environment.
Forecast of Solar and Geomagnetic Activity 21 November - 17 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 22 November - 07 December, and 10-17 December due to recurrent CH HSS influence.
Geomagnetic field activity is expected to be at unsettled to active levels on 21-29 November and 07-11 December, with G1 (Minor) geomagnetic storm levels likely on 22-24 November, due to recurrent CH HSS effects.
