# 3-Day Forecast
#
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 01-Mar 03 2026 is 4.33 (below NOAA
Scale levels).

NOAA Kp index breakdown Mar 01-Mar 03 2026

Mar 01 Mar 02 Mar 03
00-03UT 3.33 3.33 2.00
03-06UT 4.33 3.67 2.67

21-00UT 3.00 3.00 2.33

Rationale: No G1 (Minor) or greater geomagnetic storms are expected.

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 01-Mar 03 2026

Mar 01 Mar 02 Mar 03
S1 or greater 1% 1% 1%

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

No radio blackouts were observed over the past 24 hours.

Radio Blackout Forecast for Mar 01-Mar 03 2026

Mar 01 Mar 02 Mar 03
R1-R2 25% 25% 25%
R3 or greater 5% 5% 5%

Rationale: There exists a chance for R1-R2 (Minor-Moderate) radio
blackouts over 01-03 Mar.
