A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 4 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Oct 08-Oct 10 2025 is 4.67 (NOAA Scale
G1).

NOAA Kp index breakdown Oct 08-Oct 10 2025

             Oct 08       Oct 09       Oct 10
00-03UT       4.67 (G1)    3.00         1.67

21-00UT       3.00         1.67         1.33     

Rationale: Periods of G1 (Minor) geomagnetic storming are likely on
08 Oct due to the anticipated arrival of two slow-moving CMEs that
left the Sun on 03 Oct.

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 Oct 08-Oct 10 2025

              Oct 08  Oct 09  Oct 10
S1 or greater    5%      1%      1%

Rationale: No S1 (Minor) or greater solar radiation storms are expected.
No significant active region activity favorable for radiation storm
production is forecast.

C. NOAA Radio Blackout Activity and Forecast

No radio blackouts were observed over the past 24 hours.

Radio Blackout Forecast for Oct 08-Oct 10 2025

              Oct 08        Oct 09        Oct 10

R3 or greater   10%            5%            5%

Rationale: A moderate chance for R1-R2 (Minor-Moderate) radio blackouts
due to M-class flare activity, with a slight chance for an isolated R3
(Strong) event, will persist through 08 Oct. Probabilities undergo a
minor decrease on 09-10 Oct as Region 4236 exits the western limb.

R1-R2           40%           40%           35%
R3 or greater   10%           10%            5%

Rationale: A moderate chance for R1-R2 (Minor-Moderate) radio blackouts
due to M-class flare activity, with a slight chance for an isolated R3
(Strong) event, will persist through 08 Oct. Probabilities undergo a
minor decrease on 09 Oct as Region 4236 exits the western limb.
