NOAA Kp index breakdown Oct 23-Oct 25 2017

            Oct 23     Oct 24     Oct 25
00-03UT        3          2          6 (G2)
03-06UT        1          2          6 (G2)
06-09UT        2          2          5 (G1)
09-12UT        2          2          5 (G1)
12-15UT        1          3          4     
15-18UT        1          3          4

21-00UT        2          5 (G1)     5 (G1)

Rationale: G1 (Minor) geomagnetic storm conditions are likely late on
day two (24 Oct) and increasing to G2 (moderate) conditions on day three
(25 Oct) due to the anticipated onset of a positive polarity CH HSS.

B. NOAA Solar Radiation Activity Observation and Forecast

Solar radiation, as observed by NOAA GOES-13 over the past 24 hours, was
below S-scale storm level thresholds.

Solar Radiation Storm Forecast for Oct 23-Oct 25 2017

              Oct 23  Oct 24  Oct 25
S1 or greater    1%      1%      1%

Rationale: 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

No radio blackouts were observed over the past 24 hours.

Radio Blackout Forecast for Oct 23-Oct 25 2017

              Oct 23        Oct 24        Oct 25

R3 or greater    1%            1%            1%

Rationale: No R1 (Minor) or greater radio blackouts are expected.  No
significant active region flare activity is forecast.
