Extended Three Day Forecast:
A. NOAA Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 4 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Jun 14-Jun 16 2026 is 4.67 (NOAA Scale
G1).

Rationale: The geomagnetic field is likely to reach G1 (Minor) storm
levels on 14 Jun due to -CH HSS influences and the passage of CMEs that
left the Sun on 09 Jun and 11 Jun.
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.
Solar Radiation Storm Forecast for Jun 14-Jun 16 2026
Jun 14 Jun 15 Jun 16
S1 or greater 5% 5% 5%
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.

R1-R2 20% 20% 20%
R3 or greater 1% 1% 1%
Rationale: There is a slight chance for R1-R2 (Minor-Moderate) radio
blackouts on 14-16 Jun.
Extended Space Weather Discussion:
Solar Activity
.24 hr Summary...
Solar activity continued at low levels. All active regions were either
mostly stable or in gradual decay. The strongest flare of the period was
a C2.5/Sf flare at 13/1309 UTC associated with a filament eruption near
the SW limb. Subsequent GOES-19 CCOR-1 coronagraph imagery contained a
CME signature towards the SW beginning at 13/1345 UTC. Analysis and
modeling of the event indicated a miss well ahead of Earth.
.Forecast...
Solar activity is expected to remain at low levels through 16 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 a peak
flux of 1,519 pfu. The greater than 10 MeV proton flux remained at
background levels.
.Forecast...
The greater than 2 MeV electron flux is expected to continue to reach
high levels over 14-16 Jun. The greater than 10 MeV proton flux
is expected to continue at background levels through 16 Jun.
Solar Wind
.24 hr Summary...
Solar wind parameters reflected influence from a negative polarity CH
HSS, with a slight enhancement in IMF noted at 13/0952 UTC, which may be
associated with arrival of transient influence anticipated for early to
midday on 13 Jun. Total magnetic field strength increased from a steady
5 nT during the HSS to a peak of 8 nT at 13/0900 UTC. The Bz component
briefly reached as far south as -6 nT. Solar wind speeds increased from
a steady ~550 km/s to a peak of ~674 km/s at 13/1026 UTC, then returned
to near 550 km/s by the end of the period.
.Forecast...
The solar wind environment is expected to remain enhanced over 14-16 Jun
due to continued -CH HSS influences. Additional enhancements are
possible over 14 Jun with the anticipated passage of CMEs from 09 and 11
Jun, and again on 16 Jun with the likely glancing blow of the CME from
12 Jun.
Geospace
.24 hr Summary...
The geomagnetic field was at mostly quiet to unsettled levels, with an
isolated active period, under -CH HSS and CME influences.
.Forecast...
The geomagnetic field is likely to reach G1 (Minor) storm levels on 14
Jun due to -CH HSS influences and the passage of CMEs that left the Sun
on 09 Jun and 11 Jun. Periods of active conditions are likely on 15-16
Jun as -CH HSS influences persist, with possible weak interactions with
the CME from 12 Jun.
