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 Oct 30-Nov 01 2026 is 5.00 (NOAA Scale
G1).

21-00UT 3.67 4.00 3.33
Rationale: G1 (Minor) geomagnetic storms are likely on 31 Oct and 01 Nov
due to 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 Oct 30-Nov 01 2026
Oct 30 Oct 31 Nov 01
S1 or greater 1% 1% 1%
Rationale: No S1 (Minor) or greater solar radiation storms are expected
through 01 Nov.
C. NOAA Radio Blackout Activity and Forecast
No radio blackouts were observed over the past 24 hours.
Radio Blackout Forecast for Oct 30-Nov 01 2026
Oct 30 Oct 31 Nov 01
R1-R2 1% 1% 1%
R3 or greater 1% 1% 1%
Rationale: No R1 (Minor) or greater radio blackouts are expected through
01 Nov.
