A. NOAA Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 7 (NOAA Scale
G3).

Rationale: G1-G3 (Minor-Strong) geomagnetic storms are likely on 07 Nov,
and G1-G2 (Minor-Moderate) on 08 Nov, due to the effects of a coronal
hole combined with multiple CMEs.
B. NOAA Solar Radiation Activity Observation and Forecast
Solar radiation, as observed by NOAA GOES-18 over the past 24 hours, was
below S-scale storm level thresholds.

Rationale: There exists a slight chance for S1 (Minor) or greater solar radiation storms over 07-09 Nov due primarily to the eruptive potential
of Region 4274.

Radio blackouts reaching the R1 levels were observed over the past 24
hours. The largest was at Nov 06 2025 0431 UTC.

Rationale: G1 (Minor) geomagnetic storms are likely over 10 Nov due to potential influence from a CME that left the Sun on 07 Nov. G2
(Moderate) conditions are possible on 11-12 Nov due to anticipated
influence from a CME that left the Sun on 09 Nov.

A. NOAA Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 9 (NOAA Scale

Rationale: G4 (Severe) geomagnetic storming remains likely, primarily
during the early hours of the 13 Nov UTC-day, due to ongoing CME
effects. Primarily G1 (Minor) to G2 (Moderate) geomagnetic storming is
likely thereafter, carrying on into the early hours of the 14 Nov
UTC-day as CME effects gradually wane.
B. NOAA Solar Radiation Activity Observation and Forecast
Solar radiation, as observed by NOAA GOES-18 over the past 24 hours, was
above S-scale storm level thresholds.

Nov 13 Nov 14 Nov 15
S1 or greater 99% 75% 45%
Rationale: S1 (Minor) to S2 (Moderate) solar radiation storms are
expected to continue through 13 Nov before decreasing to the lower ends
of the S1 (Minor) threshold over the course of 14 Nov as CME influences
pass beyond the near-Earth environment.
C. NOAA Radio Blackout Activity and Forecast

Nov 13 Nov 14 Nov 15
R1-R2 85% 85% 85%

Rationale: R1-2 (Minor-Moderate) radioblackouts are expected through 15
Nov and are likely to be accompanied by isolated R3 (Strong) events as
AR 4274 makes it approach towards the western limb of the solar disk.
