# 3-Day Forecast
#
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 Jul 06-Jul 08 2026 is 4.00 (below NOAA
Scale levels).

NOAA Kp index breakdown Jul 06-Jul 08 2026

Jul 06 Jul 07 Jul 08
00-03UT 3.33 1.67 1.33
03-06UT 4.00 1.33 1.33
06-09UT 3.33 1.33 1.33
09-12UT 3.33 1.67 1.67
12-15UT 2.67 1.67 1.33
15-18UT 1.67 1.33 1.33
18-21UT 2.00 1.33 1.67
21-00UT 2.00 1.33 1.67

Rationale: No G1 (Minor) or greater geomagnetic storms are expected
through 08 Jul.

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 Jul 06-Jul 08 2026

Jul 06 Jul 07 Jul 08
S1 or greater 20% 10% 1%

Rationale: There is a slight chance for S1 (Minor) or greater solar
radiation storms on 06-07 Jul due to the complexity of the regions
transiting the western limb.

C. NOAA Radio Blackout Activity and Forecast

Radio blackouts reaching the R2 levels were observed over the past 24
hours. The largest was at Jul 05 2026 1757 UTC.

Radio Blackout Forecast for Jul 06-Jul 08 2026

Jul 06 Jul 07 Jul 08
R1-R2 75% 60% 15%
R3 or greater 20% 10% 1%

Rationale: R1-R2 (Minor-Moderate) radio blackouts are expected on 06
Jul, decreasing to likely on 07 Jul, and a slight chance on 08 Jul.
There is a slight chance for R3 (Strong) or greater events through 07
Jul.
