A. NOAA Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 6 (NOAA Scale
G2).
The greatest expected 3 hr Kp for Mar 14-Mar 16 2026 is 5.67 (NOAA Scale
G2).

Rationale: G1 (Minor) and G2 (Moderate) geomagnetic storms are expected
over 14 Mar due to coronal hole influence.
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 Mar 14-Mar 16 2026
Mar 14 Mar 15 Mar 16
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
Radio blackouts reaching the R1 levels were observed over the past 24
hours. The largest was at Mar 13 2026 0955 UTC.

Mar 14 Mar 15 Mar 16
R1-R2 25% 25% 20%
R3 or greater 1% 1% 1%
Rationale: There exists a chance for R1-R2 (Minor-Moderate) radio
blackouts over 14 Mar and a slight chance for R1-R2 (Minor-Moderate)
radio blackouts over 15-16 Mar.
Extended Space Weather Discussion:
Solar Activity
.24 hr Summary...
Solar activity reached moderate levels. Region 4384 (N09W81, Dai/beta)
produced an M1.2/Sf (R1-Minor) flare at 13/0955 UTC, the strongest of
the period. The region continued to show rapid growth in its
intermediate and trailer spots as it approached the W limb. Decay was
observed in Regions 4390 (N26W12, Bxo/beta) and 4388 (S14W71, Bxo/beta),
with Region 4387 (N08, L=076) decaying fully to plage. Only minor
changes were observed in the remaining spotted active regions.
Other activity included a large filament eruption in the southern
hemisphere. It began slowly lifting off after ~12/2100 UTC. Subsequent
SOHO/LASCO C2 coronagraph imagery contained a CME signature to the SW
beginning at 13/0036 UTC. Analysis and modeling of the event suggests
the ejecta will predominantly pass below and ahead of Earths orbit.
However, this is a slight chance of a minor glancing blow late on 15
Mar.
No other potentially Earth-directed CMEs were observed in available
coronagraph imagery.
.Forecast...
Solar activity is expected to be at low levels, with a chance for
M-class (R1-R2/Minor-Moderate) flares over 14-15 Mar, entirely due to
the flaring potential of Region 4384. The probability of M-flares
decreases to a slight chance as this region moves beyond the limb on 16
Mar.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux reached high levels with a peak
flux of 1,170 pfu observed at 13/1725 UTC. The greater than 10 MeV
proton flux was at background levels.
.Forecast...
The greater than 2 MeV electron flux is expected to reach moderate
levels on 14 Mar, and high levels again on 15-16 Mar. The greater than
10 MeV proton flux is expected to continue at background levels through
16 Mar.
Solar Wind
.24 hr Summary...
Solar wind parameters contained enhancements after ~13/0500 UTC,
indicative of the arrival of a CIR before an anticipated CH HSS. Total
magnetic field strength increased to a peak of 13 nT. Bz rotated as far
south as -8 nT for an hour period around 0715 UTC, then rotated back
north where it stayed for the majority of the rest of the period. Solar
wind speeds increased from ~400 km/s to ~700 km/s, beginning after
13/0830 UTC. Phi angle transitioned from negative to positive at 13/0854
UTC.
.Forecast...
Enhanced solar wind conditions are expected to prevail through 16 Mar
due to positive polarity CH HSS influences.
Geospace
.24 hr Summary...
The geomagnetic field was at quiet to G2 (Moderate) geomagnetic storm
levels.
.Forecast...
Periods of G1 (Minor) and G2 (Moderate) geomagnetic storming are
expected early on 14 Mar, with active conditions likely on 15-16 Mar,
due to positive polarity CH HSS influences.
