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 Jun 12-Jun 14 2024 is 2.33 (below NOAA
Scale levels).

21-00UT       2.33         1.67         1.33

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

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 Jun 12-Jun 14 2024

              Jun 12  Jun 13  Jun 14
S1 or greater   75%      5%      5%

Rationale: The greater than 10 MeV proton flux is expected to reached S1
(Minor) solar radiation levels on 12 Jun. Levels should begin to tapper
off by 13 Jun, and eventually return to near background levels by 14
Jun.

C. NOAA Radio Blackout Activity and Forecast

No radio blackouts were observed over the past 24 hours.

Radio Blackout Forecast for Jun 12-Jun 14 2024

              Jun 12        Jun 13        Jun 14
R1-R2           25%           25%           25%
R3 or greater   10%            5%            5%

Rationale: There is a decreasing chance for isolated moderate activity
(R1/Minor Radio Blackouts) through 14 Jun.
