SUMMARY: 10cm Radio Burst
Begin Time: 2025 Nov 10 0908 UTC
Maximum Time: 2025 Nov 10 0917 UTC
End Time: 2025 Nov 10 0943 UTC
Duration: 35 minutes
Peak Flux: 860 sfu
Latest Penticton Noon Flux: 176 sfu
Description: A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.

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 Nov 11-Nov 13 2025 is 7.33 (NOAA Scale
G3).

21-00UT 5.67 (G2) 4.00 3.00
Rationale: Periods of G1-G2 (Minor-Moderate) geomagnetic storming are
likely on 11-13 Nov in response to the anticipated arrival of the 09 Nov
and 10 Nov asymmetric halo CME.
B. NOAA Solar Radiation Activity Observation and Forecast
Solar radiation, as observed by NOAA GOES-18 over the past 24 hours, was
above S-scale storm level thresholds.
Solar Radiation Storm Forecast for Nov 11-Nov 13 2025
Nov 11 Nov 12 Nov 13
S1 or greater 99% 50% 35%
Rationale: The greater than 10 MeV proton flux to is expected to
continue at S1 (Minor) storm levels on 11 Nov following the X1.2 flare
from Region 4274. There is a chance for S1 (Minor) storm levels on
12-13 Nov due to the flare potential and location of Region 4274.
C. NOAA Radio Blackout Activity and Forecast
Radio blackouts reaching the R3 levels were observed over the past 24
hours. The largest was at Nov 10 2025 0919 UTC.
Radio Blackout Forecast for Nov 11-Nov 13 2025
Nov 11 Nov 12 Nov 13
R1-R2 75% 75% 75%
R3 or greater 35% 35% 35%
Rationale: R1/R2 (Minor/Moderate) radio blackouts are likely, with a
chance for an isolated R3 (Strong) event on 11-13 Nov.
Extended Space Weather Discussion:
Solar Activity
.24 hr Summary...
Solar activity reached high levels this period due to an X-class flare
from Region 4274 (N24W24, Ekc/beta-gamma-delta). The long-duration
X1.2/2B flare (R3-Strong) occurred at 10/0919 UTC, with associated
Type-II (1321 km/s) and Type-IV radio sweeps, and an F10.7 cm radio
burst (860 sfu). This event also had a Castelli-U radio burst as well as
an asymmetric halo CME with the bulk of the ejecta off the NW limb.
Modelling of the event indicated arrival early on 12 Nov.
Region 4274 continued to exhibit growth over the period with some
separation within its intermediate spots. Movement observed along the
inversion lines through the southern half of the spot group indicates
the potential for further shearing. The larger trailing spots appeared
to show some rotation. The rest of the spotted regions were either
stable or in decay. New Region 4280 (S09E61, Bxo/beta) was numbered.
.Forecast...
Solar activity is expected to be moderate (R1-R2, Minor-Moderate) with a
chance for further X-class (R3-Strong) activity on 11-13 Nov due to the
flare potential of Region 4274.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux reached high levels with a peak
flux of 4,280 pfu observed at 10/1535 UTC.
The greater than 10 MeV proton flux began to increase after 10/1000 UTC
following the X1.2 flare at 10/0919 UTC. S1 (Minor) levels were reached
at 10/1125 UTC with a peak flux of 28.2 pfu observed at 10/1405 UTC.
.Forecast...
The greater than 2 MeV electron flux is expected to reach high levels on
11 Nov followed by a decrease to moderate levels on 12-13 Nov following
the arrivals of the 09-10 CMEs.
The greater than 10 MeV proton flux is expected to continue above the S1
(Minor) threshold through 11 Nov with a decreasing chance on 12-13 Nov.
Further enhancements are possible with the arrival of the 09-10 CMEs on
11 and 12 Nov.
Solar Wind
.24 hr Summary...
Solar wind parameters were enhanced under continued HSS influence. Solar
wind speed ranged from 475-597 km/s. Total field ranged from 1-8 nT
while the Bz component was between +7/-4 nT. Phi angle was mostly
negative.
.Forecast...
The solar wind environment is expected to become further enhanced on
11-13 Nov with the arrival of two CMEs. The 09 Nov CME is expected to
arrive late on 11 Nov followed by the 10 Nov CME early on 12 Nov (UTC
day). Solar wind speeds exceeding 700 km/s is likely following the
arrival.
Geospace
.24 hr Summary...
The geomagnetic field was at quiet to active levels.
.Forecast...
G1-G2 (Minor-Moderate) levels are likely with the arrival of the 09 Nov
CME by late on 11 Nov. G1-G3 (Minor-Strong) levels are likely on 12 Nov
with the arrival of the 10 Nov CME. Unsettled to G1 storming is likely
on 13 Nov as conditions slowly wane.
