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 24-Mar 26 2026 is 3.67 (below NOAA
Scale levels).

Rationale: No G1 (Minor) or greater geomagnetic storms are expected
through 26 Mar.
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.
