Extended Three Day Forecast:

A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 5 (NOAA Scale
G1).
The greatest expected 3 hr Kp for Jul 01-Jul 03 2026 is 5.67 (NOAA Scale
G2).

18-21UT       3.00         2.00         4.33
21-00UT       4.33         1.67         4.33

Rationale: G1 (Minor) storming is expected, with a chance for isolated
periods reaching G2 (Moderate) through early on 01 Jul as CME activity
persists. Unsettled to active conditions are expected on 02 Jul with the
possible arrival of another CME that left the Sun on 27 Jun, but
confidence is lower for this event. G1-G2 conditions are possible by 03
Jul pending further analysis of the CME associated with the X1.1 flare.

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 Jul 01-Jul 03 2026

              Jul 01  Jul 02  Jul 03
S1 or greater   20%     20%     20%

Rationale: The probability for S1 (Minor) or greater solar radiation
storms increases beginning 03 Jul as Regions 4478 and 4479 continue to
develop and move westward into a more favorable position to connect with
Earth.

C. NOAA Radio Blackout Activity and Forecast

Radio blackouts reaching the R3 levels were observed over the past 24
hours. The largest was at Jun 30 2026 2050 UTC.

Radio Blackout Forecast for Jul 01-Jul 03 2026

              Jul 01        Jul 02        Jul 03
R1-R2           70%           70%           70%
R3 or greater   20%           20%           20%

Rationale: Isolated R1-R2 (Minor-Moderate) radio blackouts are likely
with a slight chance for R3 (Strong) or greater events primarily due to
the potential of Regions 4478 and 4479.


Extended Space Weather Discussion:

Solar Activity

.24 hr Summary...
Solar activity reached high levels due to an X1.1 flare at 30/2050 UTC
from AR 4479 (N16W31, Eki/beta-gamma-delta). Associated with the flare
were Type II (1496 km/s) and IV radio sweeps, a 410 sfu tenflare, and
EUV dimming observed at 30/2059 UTC suggesting a CME emission. This
region was also responsible for four impulsive low-level M-class flares.
Other activity included an M5.8 flare at 30/1257 UTC from Region 4475
(S09W70, Dai/beta). Region 4478 (S05W13, Fki/beta-gamma-delta), the
largest region on the disk, was not as active but produced a C9.1 flare
at 30/1958 UTC. These three regions appeared to be in a growth phase.
Several small deltas were observed on the periphery of Regions 4478 and
4479.

A full-halo CME associated with the X1.1 flare is first visible in
GOES-19 CCOR-1 imagery at 30/2145 UTC. CME analysis is ongoing at the
time of this writing, but preliminary analysis suggests Earth impacts
03-04 Jul.

.Forecast...
Solar activity is likely to reach moderate levels (R1-R2,
Minor-Moderate) with a slight chance for X-class flares (R3-Strong) due
to the flare potential of Regions 4475, 4478, and 4479.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux was at moderate to high levels with
a peak flux of 5,687 pfu observed at 30/1315 UTC. The greater than 10
MeV proton flux was at background levels.

.Forecast...
The greater than 2 MeV electron flux is expected to again reach high
levels on 01 and 03 Jul. Moderate levels are likely on 02 Jul due to the
possible arrival of the 27 Jun CME. There is a slight chance for a
greater than 10 MeV proton event (S1-Minor) due to the flare potential
of Regions 4475, 4478, and 4479.

Solar Wind

.24 hr Summary...
Solar wind parameters were enhanced due to CME arrival. Total field
strength gradually increased to 18 nT throughout the period. The Bz
component has been variable with a few southward deflections to -10 nT.
Solar wind speeds have been steady near 425 km/s. Phis has been
negative.

.Forecast...
Solar wind parameters are expected to continue to be enhanced on 01 Jul
as CME active persists. Further enhancements are possible late on 01 to
early on 02 Jul with the possible arrival of the 27 Jun CME. An
additional enhancement is possible on 03 Jul due to the likely arrival
of a CME that left the Sun late on 30 Jun.

Geospace

.24 hr Summary...
The geomagnetic field was initially quiet until the arrival of the
aforementioned CME that left the Sun on 26 Jun. Active to G1 (Minor)
conditions were observed during the latter half of the summary period.

.Forecast...
G1 (Minor) storming is expected, with a chance for isolated periods
reaching G2 (Moderate) through early on 01 Jul as CME activity persists.
Unsettled to active conditions are expected on 02 Jul with the possible
arrival of another CME that left the Sun on 27 Jun, but confidence is
lower for this event. G1-G2 conditions are possible by 03 Jul pending
further analysis of the CME associated with the X1.1 flare.

  • 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.
  • User Magnetometer ID's: Learn more
    If you have a TAFS Magnetometer and you want to add it to the graph you can do it here.
