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.
