    :Product: 3-Day Forecast
    :Issued: 2022 Jul 18 0030 UTC
    # Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center
    #
    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 Jul 18-Jul 20 2022 is 4 (below NOAA
    Scale levels).

    NOAA Kp index breakdown Jul 18-Jul 20 2022

    Jul 18 Jul 19 Jul 20
    00-03UT 2 2 2
    03-06UT 2 2 2
    06-09UT 3 3 2
    09-12UT 2 2 2
    12-15UT 1 2 2
    15-18UT 2 2 3
    18-21UT 2 2 4
    21-00UT 2 2 4

    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-16 over the past 24 hours, was
    below S-scale storm level thresholds.

    Solar Radiation Storm Forecast for Jul 18-Jul 20 2022

    Jul 18 Jul 19 Jul 20
    S1 or greater 10% 10% 10%

    Rationale: A slight chance for S1 (Minor) radiation storms persists
    through 20 Jul due to the complexity and favorable locations of a few
    active regions in the western portion of the solar disk.

    C. NOAA Radio Blackout Activity and Forecast

    No radio blackouts were observed over the past 24 hours.

    Radio Blackout Forecast for Jul 18-Jul 20 2022

    Jul 18 Jul 19 Jul 20
    R1-R2 45% 45% 40%
    R3 or greater 10% 10% 10%

    Rationale: A chance for R1-2 (Minor-Moderate), with a slight chance for
    R3 (Strong), radio blackouts will persist through 20 July given the
    current active regions on the solar disk.
