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 Mar 04-Mar 06 2026 is 4.67 (NOAA Scale
G1).
NOAA Kp index breakdown Mar 04-Mar 06 2026
Mar 04 Mar 05 Mar 06
00-03UT 4.67 (G1) 2.33 4.33
03-06UT 3.67 2.33 4.33
06-09UT 2.67 1.00 3.33
09-12UT 1.67 1.33 3.33
12-15UT 0.67 1.00 3.00

18-21UT 1.67 2.33 3.00
21-00UT 2.00 3.33 4.33
Rationale: Isolated G1 (Minor) geomagnetic storms are possible on 04 Mar
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 Mar 04-Mar 06 2026
Mar 04 Mar 05 Mar 06
S1 or greater 1% 1% 1%
Rationale: No S1 (Minor) or greater solar radiation storms are expected.
C. NOAA Radio Blackout Activity and Forecast
No radio blackouts were observed over the past 24 hours.
Radio Blackout Forecast for Mar 04-Mar 06 2026
Mar 04 Mar 05 Mar 06
R1-R2 25% 25% 25%
R3 or greater 5% 5% 5%
Rationale: There is a chance for R1-R2 (Minor-Moderate) radio blackouts,
with a slight chance for R3 (Strong) events, through 06 Mar.
