Extended Three Day Forecast:
A. NOAA Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 5 (NOAA Scale
G1).
The greatest expected 3 hr Kp for Feb 15-Feb 17 2026 is 5.67 (NOAA Scale
G2).

21-00UT 3.67 3.33 2.67
Rationale: Periods of G1-G2 (Minor-Moderate) geomagnetic storming are
expected on 15 Feb due to CIR effects and the onset of positive polarity
CH HSS influences. Weak CME enhancements are possible on 15 Feb as a CME
from 11 Feb passes in close proximity. Periods of G1 (Minor) storming
are likely on 16 Feb, with a chance for G2 (Moderate) storm periods,
under continued positive polarity CH HSS influences.
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 Feb 15-Feb 17 2026
Feb 15 Feb 16 Feb 17
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 Feb 15-Feb 17 2026
Feb 15 Feb 16 Feb 17
R1-R2 10% 10% 10%
R3 or greater 1% 1% 1%
Rationale: There is a slight chance for M-class (R1-R2/Minor-Moderate)
flares through 17 Feb.
Extended Space Weather Discussion:
Solar Activity
.24 hr Summary...
Solar activity remained at low levels. The largest flare of the period
was C1.3 at 15/0727 UTC from a plage region located near S13W46. Region
4377 (N06E52, Cro/beta) developed a few additional rudimentary spots,
while the remaining regions were stable or in decay. No Earth-directed
CMEs were detected in available imagery.
.Forecast...
Solar activity is expected to be at low levels, with a slight chance for
M-class (R1-R2/Minor-Moderate) flares through 17 Feb.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux reached moderate levels. The
greater than 10 MeV proton flux remained at background levels.
.Forecast...
The greater than 2 MeV electron flux is expected to reach moderate
levels on 15-16 Feb, before increasing to high levels on 17 Feb. The
greater than 10 MeV proton flux is expected to continue at background
levels through 17 Feb.
Solar Wind
.24 hr Summary...
Solar wind parameters were consistent with the onset of CIR effects
preceding positive polarity CH HSS influences.
Total magnetic field strength reached a peak of 15 nT. The Bz component
was sustained southward, by as much as -14 nT, between 14/1830-15/0120
UTC. Solar wind speeds steadily increased from a low of around 370 km/s
to a peak of around 700 km/s by the end of the period.
.Forecast...
The solar wind environment is expected to remain enhanced through 17 Feb
due to CIR influences, followed by the onset of positive polarity CH HSS
influences. Weak CME enhancements are possible on 15 Feb as a CME from
11 Feb passes in close proximity.
Geospace
.24 hr Summary...
The geomagnetic field reached G1 (Minor) storm levels in response to CIR
effects preceding positive polarity CH HSS influences.
.Forecast...
Periods of G1-G2 (Minor-Moderate) geomagnetic storming are expected on
15 Feb due to CIR effects and the onset of positive polarity CH HSS
influences. Weak CME enhancements are possible on 15 Feb as a CME from
11 Feb passes in close proximity. Periods of G1 (Minor) storming are
likely on 16 Feb, with a chance for G2 (Moderate) storm periods, under
continued positive polarity CH HSS influences. Active conditions are
likely on 17 Feb as CH HSS influences begin to wane.
