Highlights of Solar and Geomagnetic Activity
28 November - 04 December 2016
Solar activity ranged from very low to moderate levels over the
period. Very low levels were observed on 01-03 December, low levels
were observed on 28 and 30 November and again on 04 December while
moderate levels were observed on 29 November. Region 2615 (S07,
L=139, class/area Dai/170 on 04 December) was responsible for the
majority of the solar activity over the period since its inception
late on 28 November. This region was responsible for 11 C-class
flares and two M-class flares; an M1/Sn at 29/1723 UTC and an M1/Sf
at 29/2338 UTC. No Earth-directed coronal mass ejections were
observed during the 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 with a maximum flux of 41,607 pfu
observed at 28/1640 UTC.
Geomagnetic field activity ranged from quiet to unsettled levels
during the period. The period began as solar wind parameters were
slowly recovering from a positive polarity coronal hole high speed
stream (CH HSS). Solar wind speeds slowly decreased from
approximately 570 km/s early in the period to near 280 km/s by the
end. Total field values ranged from 1 nT to 7 nT. The geomagnetic
field was at quiet to unsettled levels on 28 November. Quiet levels
were observed from 29 November through 04 December.
