A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 5 (NOAA Scale
G1).
The greatest expected 3 hr Kp for Nov 08-Nov 10 2026 is 5.00 (NOAA Scale
G1).

NOAA Kp index breakdown Nov 08-Nov 10 2026

             Nov 08       Nov 09       Nov 10
00-03UT       4.67 (G1)    5.00 (G1)    3.67         
03-06UT       5.00 (G1)    4.00         3.67         
06-09UT       4.00         4.67 (G1)    2.67         
09-12UT       3.00         4.00         2.67         
12-15UT       3.33         2.67         1.67         
15-18UT       3.67         2.67         1.67         
18-21UT       4.67 (G1)    3.67         1.67         
21-00UT       4.67 (G1)    2.67         2.67         

Rationale: The geomagnetic field is expected to reach G1 (Minor)
geomagnetic storm levels, with a chance for G2 (Moderate) storm levels
on 08 Nov, likely continuing into 09 Nov due to anticipated influence
from a negative polarity CH HSS

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 08-Nov 10 2026

              Nov 08  Nov 09  Nov 10
S1 or greater   15%     15%     15%

Rationale: There is a slight chance for the greater than 10 MeV proton
flux to exceed S1 (Minor) levels over 08-10 Nov.

C. NOAA Radio Blackout Activity and Forecast

Radio blackouts reaching the R1 levels were observed over the past 24
hours. The largest was at 07/1842Z UTC.

Radio Blackout Forecast for Nov 08-Nov 10 2026

              Nov 08        Nov 09        Nov 10
R1-R2           60%           60%           60%
R3 or greater   20%           20%           20%

Rationale: R1-R2 (Minor-Moderate) radio blackouts are likely, with a
chance for an isolated R3 (Strong) event over 08-10 Nov.
