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 07-Jun 09 2026 is 7.00 (NOAA Scale
G3).

Rationale: Periods of G1-G3 (Minor-Strong) geomagnetic storming are
likely on 08 Jun, with G1-G2 (Minor-Moderate) storm periods likely on 09
Jun, following the anticipated arrival of a CME that left the Sun on 06
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 07-Jun 09 2026
Jun 07 Jun 08 Jun 09
S1 or greater 15% 25% 10%
Rationale: There is a slight chance for S1 (Minor) solar radiation
storms on 07 and 09 Jun, with a chance for S1 levels on 08 Jun following
the anticipated shock arrival of the 06 June CME.
C. NOAA Radio Blackout Activity and Forecast
Radio blackouts reaching the R1 levels were observed over the past 24
hours. The largest was at Jun 06 2026 1401 UTC.
Radio Blackout Forecast for Jun 07-Jun 09 2026
Jun 07 Jun 08 Jun 09
R1-R2 55% 55% 55%
R3 or greater 10% 10% 10%
Rationale: R1-R2 (Minor-Moderate) radio blackouts are likely, with a
slight chance for R3 (Strong) or greater events, over 07-09 Jun.
Extended Space Weather Discussion:
Solar Activity
.24 hr Summary...
Solar activity reached moderate levels due to an M1.8/2N flare from
Region 4461 (S21E18, Cro/beta), which was the largest of the period.
Region 4456 (N18W34, Dai/beta-gamma-delta) was responsible for a C8.8
flare at 06/1318 UTC as it continued to undergo evolution, gaining
additional spots with asymmetric penumbra and a relatively weak delta
signature in its intermediate area. New spots just north of Region 4462
(N16E19, Dai/beta) formed, but remain unnumbered at this time as we
await corroborating solar observatory reports.
The aforementioned M1.9/2N flare resulted in a F10.7 cm radio burst
measuring 190 sfu, an approximately 11 degree-long filament eruption
centered near S25E28, and a type-II sweep with an estimated speed of 838
km/s. The resulting partial halo CME, first seen in LASCO C2 coronagraph
imagery at 06/1401 UTC, is anticipated to arrive around midday on 08
June.
.Forecast...
A chance for isolated M-class flare activity (55%) will persist through
09 June primarily due to the flare potential exhibited by Regions 4456,
4458 and 4462 alongside the flare history of Region 4455.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels with a peak flux of 1,280 pfu at 06/1710 UTC. The greater
than 10 MeV proton flux became enhanced just after 06/1515 UTC due to
the eruption from the M1.8 flare event.
.Forecast...
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to remain at high levels through 07 June before returning to
normal to moderate levels on 08 June with the arrival of the 06 June
CME. 2 MeV electron flux levels are likely to return to high levels by
the close of 09 June. The greater than 2 MeV proton flux is expected to
remain at background levels with a chance for an S1 (Minor) event on 08
June with the shock arrival of the 06 June CME.
Solar Wind
.24 hr Summary...
Solar wind parameters reflected waning CME and possible weak positive
polarity CH HSS influences. Total field decreased to 4-5 nT and the Bz
component was mostly benign with only brief southward deflections
reaching -5 to -6 nT early in the reporting period. Solar wind speeds
mostly averaged between 550 km/s to 650 km/s. Phi was predominantly
positive.
.Forecast...
Current solar wind conditions are expected to continue to wane over the
course of 07 June. A disturbed solar wind environment is expected to
return by early to mid UTC-day on 08 June with the shock arrival from
the 06 June CME bringing enhanced magnetic field and much faster solar
wind speeds. The enhancements are anticipated to continue into 09 June
with a waning trend beginning by mid UTC-day.
Geospace
.24 hr Summary...
Geomagnetic field activity was at quiet to active levels.
.Forecast...
Quiet to unsettled levels are expected on 07 June under the current
solar wind regime. G1-G2 (Minor-Moderate), with isolated periods of G3
(Strong), geomagnetic storming are likely to begin by mid UTC-day on 08
June with the arrival of the CME that left the Sun on 06 June. G1-G2
(Minor-Moderate) geomagnetic storming is likely to linger into the early
portions of 09 June before giving way to unsettled to active conditions.
