Extended Three Day Forecast:

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 Jun 06-Jun 08 2026 is 4.67 (NOAA Scale
G1).

Rationale: G1 (Minor) geomagnetic storming are expected during the
middle portions of 06 June due to lingering CME effects. Quiet to
unsettled conditions are expected on 07-08 June as any CME and weak
CH HSS effects gradually wane.

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.

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.

Rationale: There is a chance for R1-R2 (Minor-Moderate) radio blackouts,
and a slight chance for R3 (Strong) or greater events, over 06-08 Jun.


Extended Space Weather Discussion:

Solar Activity

.24 hr Summary...
Solar activity remained at low levels with isolated C-class flare
activity observed. Region 4462 (N16E27, Dai/beta) produced a C4.7 flare
at 05/2245 UTC, the strongest of the period, as the region underwent
evolution and gained additional spots. Region 4455 (N15W55,
Dsi/beta-gamma) continued to display signs of gradual decay as it
produced a C4.1 flare at 05/1503 UTC. Region 4456 (N17W27,
Cro/beta-gamma), which had
previously decayed to plage, underwent rapid flux emergence as it
reformed and exhibited a mixed polarity configuration. Region 4458
(S05W42, Dao/beta) underwent consolidation and growth in its
trailing penumbra while forming a weak delta signature, but was
relatively quiet in comparison to other active regions. Finally, new
Region 4464 (S12E58, Cai/beta) was numbered.

The halo CME first observed in GOES CCOR-1 imagery at approximately
05/0945 UTC was determined to have originated on the far side of the
Sun. No Earth-directed CMEs were observed in available coronagraph
imagery.

.Forecast...
Solar activity is expected to remain at low levels, but with a high
chance (50%) for isolated M-class flare activity through 08 June.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux at geosynchronous orbit was at low
to moderate levels. The greater than 10 MeV proton flux remained at
background levels.

.Forecast...
The greater than 2 MeV electron flux at geosynchronous orbit is
anticipated to rise to high levels on 06 June in response to CME
effects, and remain high through 08 June. The greater than 10 MeV proton
flux is expected to remain at background levels barring a new
significant event particularly from Regions 4455 or 4458.

Solar Wind

.24 hr Summary...
Solar wind parameters reflected CME arrivals from the 03 June events
beginning at 05/0425 UTC. Total field jumped from 7 nT to 17 nT with
initial shock arrival and then reached a peak of 20 nT. The Bz component
of the IMF was initially northward with shock arrival, but eventually
rotated southward reaching extended periods of southward deflection
measuring up to -17 nT. Solar wind speeds initially increased to around
570 km/s during shock arrival, but then gradually increased over the
course of the period to a range between 640-740 km/s. Total field began
to settle and return to nominal-like levels after ~05/1920 UTC with what
was likely magnetic cloud or magnetic cloud periphery passage. Phi was
predominantly positive with brief excursions into a negative solar
sector.

.Forecast...
An additional disturbance to the solar wind environment cannot be ruled
out primarily for the remainder of 06 June due to any lingering CME
influences. Lingering CME and possible positive polarity CH HSS
influences are expected to wane over the course of 07 and 08 June.

Geospace

.24 hr Summary...
Geomagnetic field activity reached G1 (Minor) geomagnetic storm levels
with an isolated bout of G2 (Moderate) storming during the 1500-1800 UTC
reporting period.

.Forecast...
G1-G2 (Minor-Moderate) geomagnetic storming is expected during the early
portions of 06 June due to lingering CME effects. Quiet to unsettled
conditions are expected on 07-08 June as any CME and weak CH HSS effects
slowly come to a close.

  • GRAPH OPTIONS: Learn more
    It is recommended that you start out with the default options. As you get used to AF you can disable additional information and combine data series' together to maxamise the use of screen space.

  • DATA SOURCES: Learn more
    Some data sources can only be enabled or disabled via the tick box. Others are disabled using the slider set to 0, or enabled by setting the slider from 0.5 to 4. This number also represents the thinkness of the line plot onto the graph.

  • '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.

  • 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.
  • 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.

  • 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.
    There is a mix of govenment and citizen science stations listed here, including two run by Aurora Forecast in Hobart.
