Highlights of Solar and Geomagnetic Activity 27 Nov-3 Dec 2017

Solar activity was at very low levels. The only spotted region on
the disk, Region 2689 (N13, L=108, class/area Cao/060 on 26 Nov),
was quiet and stable. No Earth-directed CMEs were detected.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
moderate flux levels throughout the period. A maximum flux of 602
pfu was observed at 27/1435 UTC.

Geomagnetic field activity was at predominately quiet levels through
the period. Isolated unsettled and active periods were observed on
28 and 30 Nov and again on 01-02 Dec due to waning, negative
polarity CH HSS influence. Solar wind speed averaged about 425 km/s
through the period with a peak speed of 525 km/s observed midday on
30 Nov and again early on 01 Dec.

FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 04 – 30 DECEMBER 2017

Solar activity is expected to be at very low levels thoughout the
outlook period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach high levels on 05-10, 12-17 and 19-21 Dec due to
recurrent CH HSS influence. Normal to moderate levels are expected
for the remainder of the outlook period.

Geomagnetic field activity is expected to be at G1 (Minor) levels on
04-06 Dec and 18 Dec with G2 (Moderate) levels expected on 04-05 Dec
due to recurrent CH HSS effects. Unsettled to active levels are
expected on 07-08, 11-14, 17-21 and 27-28 Dec due to recurrent CH
HSS effects. Mostly quiet levels are expected for the remainder of
the outlook period.
