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 Jul 06-Jul 08 2026 is 2.67 (below NOAA

Rationale: No G1 (Minor) or greater geomagnetic storms are expected.  No

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.

              Jul 06  Jul 07  Jul 08
S1 or greater   10%     10%      5%

Rationale: There is a slight chance for a greater than 10 MeV proton
event (S1-Minor) on 06-07 Jul due to the recent and potential flare
activity of Regions 4478, 4479, and 4482.

C. NOAA Radio Blackout Activity and Forecast

Radio blackouts reaching the R2 levels were observed over the past 24
hours. The largest was at Jul 05 2026 1757 UTC.

Radio Blackout Forecast for Jul 06-Jul 08 2026

              Jul 06        Jul 07        Jul 08
R1-R2           75%           55%           20%
R3 or greater   20%           10%            5%

Rationale: R1-R2 (Minor-Moderate) radio blackouts are expected, with a
slight chance for an isolated R3 (Strong) event, through 06 Jul. As
Regions 4479 and 4480 rotate around the west limb by 07 Jul, activity is
expected to decrease. However, moderate levels are likely to persist
until these regions rotate another day beyond the limb. Activity should
decrease to a slight chance for R1-R2 (Minor-Moderate) levels on 08 Jul
as these regions complete their transit of the limb.


Extended Space Weather Discussion:

Solar Activity

.24 hr Summary...
Solar activity decreased slightly, but remained at high levels with five
M-class (R1/R2-Minor/Moderate) flares observed during the period. Region
4479 (N17W91, Eko/beta-gamma-delta) was responsible for all five events,
the largest being an M5.3 (R2-Moderate) at 05/1757 UTC, as it transited
the W limb. One of the M-flares, an M1.4 at 05/1645 UTC, had an
associated Type II sweep (959 km/s velocity) and a CME off the WNW limb.
Modeling suggests this CME will pass well ahead of Earths orbit. Along
with the other three M-class flares, this region also contributed
multiple C-class flares throughout the period.

Regions 4478 (S06W83, Eko/beta-gamma) and 4482 (S09E61, Eko/beta-gamma)
each added low-level C-class flares. Region 4482 was the only active
spot group to exhibit any sort of growth, with the remaining regions
remaining unchanged or in slight decay.

A CME first noted in LASCO C2 imagery around 06/0624 UTC that was
associated with a filament lift-off centered near N18E70, was analyzed
and is not expected to have an Earth-directed component.

.Forecast...
Solar activity is expected to remain at moderate levels (R1-R2,
Minor-Moderate) with a slight chance for X-class flares (R3-Strong),
through 06 Jul. As Regions 4479 and 4480 rotate around the west limb by
07 Jul, activity is expected to decrease. However, moderate levels
are likely to persist until these regions rotate another day beyond the
limb. Activity should decrease to a slight chance for (R1-R2,
Minor-Moderate) levels on 08 Jul as these regions complete their transit
of the limb.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels late in the period. The greater than 10 MeV proton flux was
near background levels.

.Forecast...
The greater than 2 MeV electron flux is expected to be at moderate
to high levels on 06-08 Jul. There is a slight chance for a greater than
10 MeV proton event (S1-Minor) on 06-07 Jul due to the recent and
potential flare activity of Regions 4478, 4479, and 4482.

Solar Wind

.24 hr Summary...
Solar wind parameters continued to wane from diminishing CME effects
from the 30 Jun CME, coupled with influence from +CH72. Total field
strength averaged 4-6 nT, the Bz component was mostly southward from -1
to -5 nT, and solar wind speeds decreased to average around 450 km/s.
Phi was near neutral with a slightly positive bias throughout the
period.

.Forecast...
Slightly enhanced solar wind conditions are likely to persist through 06
Jul from diminishing CME effects from the 30 Jun CME, coupled with
influence from +CH72. A return to near background levels is expected for
07-08 Jul, barring any interaction with potential CME activity from the
01-02 Jul events.

Geospace

.24 hr Summary...
Geomagnetic field activity was mostly unsettled with isolated active
periods early.

.Forecast...
Diminishing CME effects from the 30 Jun CME, coupled with decreasing
influence from +CH72, should keep conditions at quiet to unsettled
levels, with isolated active periods possible on 06 Jul. Barring
additional CME activity from the 01-02 Jul CME, mostly quiet to
unsettled levels are likely on 07-08 Jul.

  • 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.
