Extended Three Day Forecast:
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 Oct 23-Oct 25 2018 is 3 (below NOAA
Scale levels).

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-15 over the past 24 hours, was
below S-scale storm level thresholds.
Solar Radiation Storm Forecast for Oct 23-Oct 25 2018
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.

Oct 23 Oct 24 Oct 25
R1-R2 1% 1% 1%
R3 or greater 1% 1% 1%
Rationale: No R1 (Minor) or greater radio blackouts are expected. No
significant active region flare activity is forecast.
Extended Space Weather Discussion:
Solar Activity
.24 hr Summary...
Solar activity was very low and the solar disk was spotless. No CMEs
were observed in coronagraph imagery.
.Forecast...
Solar activity is expected to be very low on 23-25 Oct.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux reached moderate levels this period
and the greater than 10 MeV proton flux was steady at background levels.
.Forecast...
The greater than 2 MeV electron flux is expected to reach moderate to
high levels on 23-25 Oct and the greater than 10 MeV proton flux is
expected to persist at background levels throughout the forecast period.
Solar Wind
.24 hr Summary...
Solar wind parameters were at near-background levels. Solar wind speeds
were less than 350 km/s by the end of the reporting period. Both total
field and the Bz component were benign and unremarkable. Phi angle was
indicative of a positive solar sector.
.Forecast...
Near-background conditions are expected on 23 Oct. An enhanced solar
wind is anticipated on 24-25 Oct as a result of a recurrent, negative
polarity CH HSS.
Geospace
.24 hr Summary...
The geomagnetic field was at quiet levels.
.Forecast...
Quiet levels are expected on 23 Oct. Mostly unsettled levels are
expected 24-25 Oct in response to a recurrent, negative polarity CH HSS.
