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 NOV -
17 DEC 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.
