Product: 3-Day Forecast - Issued: 2026 Aug 06 1250 UTC
Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center.

Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 1 (below NOAA Scale levels). The greatest expected 3 hr Kp for Aug 06-Aug 08 2026 is 3.67 (below NOAA Scale levels).

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

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.

Rationale: No S1 (Minor) or greater solar radiation storms are expected. No significant active region activity favorable for radiation storm production is forecast.

Radio Blackout Activity and Forecast

No radio blackouts were observed over the past 24 hours.

Rationale: With ongoing region decay and several active regions in the western hemisphere expected to rotate off the disk over the coming days, there is a decreasing chance for M-class (R1-R2/Minor-Moderate) flares over 06-08 Aug. Current Solar Orbiter HMI imagery suggests no significant returning regions during the forecast period.
