3 Day Forcast for K-Index - Current Day is 4 at 22:53 UTC

The K-index indicates background noise on 160 thru 40 meters.
0 to 2 = Low Noise levels: S1 to S2
3 to 4 = Moderate Noise levels: S2 to S3
5 to 7 = High Noise levels: S4 to S9
8 to 9 = Radio Blackouts.

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.

S1 or greater    1%      1%      5%

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

C. NOAA Radio Blackout Activity and Forecast

Radio blackouts reaching the R1 levels were observed over the past 24
hours. The largest was at Dec 03 2022 1741  UTCC.

Radio Blackout Forecast for Dec 04-Dec 06 2022

              Dec 04        Dec 05        Dec 06
R1-R2           25%           25%           25%
R3 or greater    5%            5%            5%

A chance for R1-2 (Minor-Moderate) radio blackouts from
M-class flare activity will persist through the forecast period mainly
due to the potential exhibited by Regions 3153 and 3155 as well as the
recent history of Region 3157.
