Extended Three Day Forecast:

A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 3 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Jun 08-Jun 10 2026 is 6.67 (NOAA Scale
G3).

21-00UT       5.67 (G2)    4.00         2.67

Rationale: Periods of G1-G3 (Minor-Strong) geomagnetic storming are
likely on 08 Jun, with G1-G2 (Minor-Moderate) levels likely on 09 Jun,
due to the anticipated passage 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 08-Jun 10 2026

              Jun 08  Jun 09  Jun 10
S1 or greater   25%      5%      5%

Rationale: There is a chance for the greater than 10 MeV proton flux to
reach S1 (Minor) levels on 08 June with the shock arrival of the 06 June
CME.

C. NOAA Radio Blackout Activity and Forecast

No radio blackouts were observed over the past 24 hours.

R3 or greater   10%           10%           10%

Rationale: R1-R2 (Minor-Moderate) radio blackouts are likely, with a
slight chance for an R3 (Strong) or greater event, over 08-10 Jun.

Extended Space Weather Discussion:

Solar Activity

.24 hr Summary...
Solar activity returned to low levels with only lower level C-class
flare activity. Region 4455 (N15W75, Hsx/alpha) underwent decay and
remained relatively quiet. Region 4456 (N17W48, Dai/beta-gamma)
underwent minor decay as well and produced a C3.3 flare at 07/0419 UTC,
which was the largest of the period. Regions 4462 (N15E05, Dsi/beta) and
4464 (S12E38, Dai/beta) experienced growth as they gained additional
spots and tacked on C-class flares as well.

No new Earth-directed CMEs were observed in available coronagraph
imagery.

.Forecast...
A chance for isolated M-class flare activity (55%) will persist through
10 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 2,870 pfu at 07/1540 UTC. The greater
than 10 MeV proton flux remained slightly enhanced due to the eruption
from the M1.8 flare event on 06 June, but was well below the S1 (Minor)
radiation storm threshold

.Forecast...
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to return 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 and continue at high
levels through 10 June. The greater than 10 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 positive polarity CH HSS influences.
Total field primarily ranged 4-5 nT and the Bz component was +/- 4 nT.
Solar wind speeds peaked at approximately 589 km/s, but overall
gradually declined to under 550 km/s.

.Forecast...
A disturbed and enhanced solar wind environment is expected by early to
mid UTC-day on 08 June with the shock arrival from the 06 June CME
bringing enhanced magnetic field and faster solar wind. These
enhancements are anticipated to continue into 09 June before gradually
diminishing through 10 June.

Geospace

.24 hr Summary...
Geomagnetic field activity was at quiet to unsettled levels.

.Forecast...
G1-G2 (Minor-Moderate) 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. G3 (Strong) geomagnetic storming is likely during the latter half
of 08 June, but this outcome is dependent upon how much the CME has
expanded into the Sun-Earth line as the model indicates a bulk of the
material to be mostly south and east of Earth. 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 that carry into
10 June.

'The' Aurora Forecast Index: Learn more
These are two good options for predicting Auroras.

The Aurora Forecast Index takes into account many data sources. As a general rule if it stays high for many hours there is a good possibility of an Aurora present.

Aurora Forecast website usage is also a good indicator, as visitors to the site come from many traffic sources. General internet and community chatter transplating to visits is a great indicator.

AF Index (Experemental) AF Community Activity (Hits)
Planatary K Index (Kp): Learn more
The Kp number is a system of measuring aurora strength. The range goes from 0 to 9 (0 being calm, 1 very weak, all the way up to 9, which would represent a major geomagnetic storm with strong auroras visible).

Kp 5 and above is classified as a geomagnetic storm. Most Aurora Hunters consider prolonged 3+ or higher worth investigation.

Ovation (Model) Short Term Forecast (GW):' Learn more
The Ovation-Prime Model produced by SWPC calculates the energy interacting with the Earths magnetic field. This is a good indicator for Aurora activity.

Northern Hemisphere (Aurora Borealis) Southern Hemisphere (Aurora Australis)
DSCOVR Observatory (L1): Learn more

The DSCOVR or Deep Space Climate Obervatory sits 1.5 million Kilometers from Earth, between the Earth and the Sun in the L1 orbit point, the neutral gravity point between the Earth and the Sun. DSCOVR provides space weather readings, allowing for up to an hour of warning on weather events. This is why DSCOVR's data appears in the future on the graph.

Strong negative Bz direction is linked to Aurora's because the solar wind magnetic direction is in direct oposition with the Earths magnetic field.

ACE Observatory (L1): Learn more

ACE or Advanced Composition Explorer sits 1.5 million Kilometers from Earth, between the Earth and the Sun in the L1 orbit point, the neutral gravity point between the Earth and the Sun. ACE has now been replaced by DSCOVR, but the data is still useful for comparing to DSCOVR.

GOES Satalites: Learn more

GOES or Geostationary Operational Environmental Satellites sit 46 Kilometers above the Earth in geostationary orbit. They provide local space weather data and are a good indicator for current geomagnetic conditions.

Primary Secondary Variation (Pri - Sec)
Terrestrial Magnetometer Sources: Learn more
Terrestrial or surface magnetometers detect fluctuations in the Earths magnetic field from the ground.
These do not work as well as satalites as the magnetic field obsorbs some of the effects from the solar winds.
