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 Mar 06-Mar 08 2025 is 4.00 (below NOAA
Scale levels).

18-21UT 2.33 1.33 3.00
21-00UT 2.33 1.33 4.00

Rationale: No G1 (Minor) or greater geomagnetic storms are expected. No significant transient or recurrent solar wind features are forecast.

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 06-Mar 08 2025

Mar 06 Mar 07 Mar 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 Mar 05 2025 1150 UTC.

Radio Blackout Forecast for Mar 06-Mar 08 2025

Mar 06 Mar 07 Mar 08
R1-R2 45% 45% 45%
R3 or greater 10% 10% 10%

Rationale: There is a chance for R1-R2 (Minor-Moderate) radio blackouts
through 08 Mar.

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 Mar 09-Mar 11 2025 is 5.00 (NOAA Scale
G1).

21-00UT 3.67 4.00 3.33

Rationale: G1 (Minor) conditions are expected on 09-10 Mar due to
influence from a negative polarity coronal hole.

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 09-Mar 11 2025
