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 Mar 06-Mar 08 2026 is 4.67 (NOAA Scale
G1).
NOAA Kp index breakdown Mar 06-Mar 08 2026
Mar 06 Mar 07 Mar 08
00-03UT 2.00 3.67 4.00
03-06UT 2.33 3.33 2.00
06-09UT 3.33 2.00 2.00
09-12UT 3.33 1.67 2.00

18-21UT 4.67 (G1) 3.67 2.67
21-00UT 4.33 3.33 3.00
Rationale: Isolated G1 (Minor) geomagnetic storms are possible on 06 Mar
due to the anticipated arrival of a CIR associated with a negative
polarity coronal hole high speed stream.
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 2026
Mar 06 Mar 07 Mar 08
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 06-Mar 08 2026
Mar 06 Mar 07 Mar 08
R1-R2 20% 20% 20%
R3 or greater 1% 1% 1%
Rationale: There is a slight chance for R1-R2 (Minor-Moderate) radio
blackouts through 08 Mar.
