Highlights of Solar and Geomagnetic Activity
30 September - 06 October 2024

Solar activity reached high levels on all seven days (30 Sep - 06
Oct). There were a total of 30 R1 (Minor) flares, two R2 (Moderate)
flares, and two R3 (Strong) flares. Region 3842 (S15, L=178,
class/area Ekc/1150 on 04 Oct) produced the largest flare of the
week, an X9.0 flare at 03/1218 UTC. This event had a Castelli-U
signature, as well as Type II (est speed 582 km/s) and Type IV radio
sweeps. Region 3842 also produced an X7.1/2b flare at 01/2220 UTC
that had a Castelli-U radio signature and a Type II radio sweep (est
speed 1246 km/s) associated with it. Additionally, Region 3842
contributed an M7.7/2n event on 30 Sep that peaked at 2359 UTC.
Region 3843 (S09, L=211, class/area Eko/290 on 04 Oct) added the
other R2 event, an M6.7/2b flare, at 03/2028 UTC. This event had a
Type II (est speed 1241 km/s) and Type IV radio sweeps associated
with it. The X7.1, X9.0, and M6.7 flares all had associated
Earth-directed CMEs that were expected to impact Earth between 04-06
Oct.

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 all seven days (30 Sep - 06 Oct).

Geomagnetic field activity reached active levels on 30 Sep as
negative polarity CH HSS influence persisted. G1 (Minor) geomagnetic
storm levels were observed on 06 Oct following the likely arrival of
one of several CMEs anticipated to impact earth.
