A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 2 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Nov 06-Nov 08 2026 is 5.00 (NOAA Scale
G1).

NOAA Kp index breakdown Nov 06-Nov 08 2026

Nov 06 Nov 07 Nov 08
00-03UT 2.33 5.00 (G1) 4.00
03-06UT 2.00 3.67 4.33
06-09UT 2.00 3.33 4.67 (G1)
09-12UT 2.33 3.33 3.00
12-15UT 2.33 3.33 3.33
15-18UT 3.67 3.33 4.00
18-21UT 4.00 3.33 5.00 (G1)
21-00UT 4.67 (G1) 3.33 4.33

Rationale: The geomagnetic field activity is likely to reach G1 (Minor) geomagnetic storm levels on 06-08 Nov, with a chance for G2 (Moderate)
levels on 07-08 Nov, due to the anticipated influences of 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 06-Nov 08 2026

Nov 06 Nov 07 Nov 08
S1 or greater 5% 5% 5%

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

Radio blackouts reaching the R1 levels were observed over the past 24
hours. The largest was at 05/1833Z UTC.

Radio Blackout Forecast for Nov 06-Nov 08 2026

Nov 06 Nov 07 Nov 08
R1-R2 35% 35% 35%
R3 or greater 10% 10% 10%

Rationale: There is a chance for R1-R2 (Minor-Moderate) radio blackouts
and a slight chance for an isolated R3 (Strong) event on 06-08 Nov,
primarily due to the potential from Regions 4565 and 4566.

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 09-Nov 11 2026 is 4.67 (NOAA Scale
G1).

NOAA Kp index breakdown Nov 09-Nov 11 2026

18-21UT 2.67 1.67 2.33
21-00UT 3.67 2.67 2.67

Rationale: G1 (Minor) geomagnetic storm levels are likely on 09 Nov due
to continued negative polarity CH HSS influences.

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 09-Nov 11 2026

Nov 09 Nov 10 Nov 11
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 09-11 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 08/0746Z UTC.

Radio Blackout Forecast for Nov 09-Nov 11 2026

Nov 09 Nov 10 Nov 11
R1-R2 60% 60% 60%
R3 or greater 15% 15% 15%

Rationale: R1-R2 (Minor-Moderate) radio blackouts are likely, with a
slight chance for an R3 (Strong) event, over 09-11 Nov.
