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 Jun 16-Jun 18 2026 is 4.00 (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-18 over the past 24 hours, was
below S-scale storm level thresholds.

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.

Rationale: There is a slight chance for R1-R2 (Minor-Moderate) radio
blackouts through 18 Jun.
Extended Space Weather Discussion:
Solar Activity
.24 hr Summary...
Solar activity was at low levels. The majority of the low level C-class
flares were observed at or beyond the NE limb near N08. The largest
flare was a C1.8 at 15/1315 UTC from Region 4465 (N08W24,
Dai/beta-gamma). Slight growth was observed in this region, particularly
in the SE trailing spots along with umbral separation within its larger
spots. Region 4464 (S14W70, Hsx/alpha) was in decay as it approached the
SW limb. No Earth-directed CMEs were observed.
.Forecast...
Solar activity is expected to remain at low levels over 16-18 Jun, with
a slight chance for M-class (R1-R2/Minor-Moderate) flares.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux reached high levels, with peak
value of 1,488 pfu observed at 15/1740 UTC. The greater than 10 MeV
proton flux remained at background levels.
.Forecast...
The greater than 2 MeV electron flux is likely to reach high levels on
16-17 Jun and decrease to moderate levels on 18 Jun. The greater than 10
MeV proton flux is expected to continue at background levels through 18
Jun.
Solar Wind
.24 hr Summary...
Solar wind parameters were near nominal levels with solar wind speed
ranging from approximately 395 to 480 km/s. Total field was at or below
5 nT, with the Bz component between +/- 4 nT. Phi angle was
predominantly negative.
.Forecast...
The solar wind environment is expected to be enhanced on 16-18 Jun due
to a possible glancing-blow arrival of a CME that left the Sun on 12
Jun, followed by the onset of positive polarity CH HSS influences.
Geospace
.24 hr Summary...
The geomagnetic field was quiet.
.Forecast...
Unsettled to active levels are expected on 16-17 Jun due to a possible
glancing blow from the 12 Jun CME followed by CH HSS onset. Quiet to
unsettled levels are expected on 18 Jun.
