Highlights of Solar and Geomagnetic Activity
11 - 17 November 2024

Solar activity ranged from low to moderate levels this period. R1
(Minor) radio blackouts were observed on 11 Nov, 13 Nov and 15-16
Nov. Regions 3889 (S09, L=006, class/area Fki/540 on 15 Nov) and
3893 (S19, L=289, class/area Cso/050 on 15 Nov) produced a majority
of the activity this period. The largest flare of the period was an
M1.7 event observed on 13/1708 UTC from Region 3889. During the
period, a total of 33 C-class and 7 M-class flares were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
normal to moderate levels.

Geomagnetic field activity ranged from quiet to active levels.
Unsettled to active levels were observed on 11 Nov and 13-17 Nov,
all associated with positive polarity coronal hole high speed
streams (CH HSSs). During the period, solar wind parameters were at
mostly nominal levels through early on 14 Nov. Early on 14 Nov,
total field increased to 14 nT, while the Bz component dropped to
-13 nT. Wind speeds increased from about 305 km/s to a peak of about
460 km/s by late on 15 Nov. Wind speeds ended the period near 310
km/s. The phi angle was in a predominately positive sector
throughout the period.
