A. NOAA Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 3 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Nov 16-Nov 18 2025 is 5.00 (NOAA Scale
G1).
Rationale: G1 (Minor) geomagnetic storms are likely over 16-17 Nov due
to the anticipated influence of a negative polarity coronal hole.
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.
Solar Radiation Storm Forecast for Nov 16-Nov 18 2025
Nov 16 Nov 17 Nov 18
S1 or greater 15% 10% 5%
Rationale: There exists a slight chance for S1 (Minor) or greater solar radiation storms over 16-17 Nov due to the eruptive potential from
Region 4274.
C. NOAA Radio Blackout Activity and Forecast
No radio blackouts were observed over the past 24 hours.

Nov 16 Nov 17 Nov 18
R1-R2 60% 55% 40%
R3 or greater 20% 15% 5%
Rationale: R1 (Minor) radio blackouts are likely, with a chance for R3 (Strong), over 16-17 Nov due to the flare potential from Region 4274. By
18 Nov, there is a chance for R1 (Minor) radio blackouts due to the
flare potential from Region 4274.

A. NOAA Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 9 (NOAA Scale
G5).
The greatest expected 3 hr Kp for Nov 13-Nov 15 2025 is 8.33 (NOAA Scale
G4).
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.
Solar Radiation Storm Forecast for Nov 13-Nov 15 2025
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
No radio blackouts were observed over the past 24 hours.

Nov 13 Nov 14 Nov 15

R3 or greater 55% 55% 55%
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.

Rationale: G1 (Minor) storm levels are likely due to the onset of
positive polarity CH HSS effects. Later on 28 Aug, G2 (Moderate) storm
levels are likely due to additional disturbances caused by the
anticipated arrival of the CMEs that left the Sun on 25-26 Aug. G1 to G2
