Rationale: No G1 (Minor) or greater geomagnetic storms are expected.  No
significant transient or recurrent solar wind features are forecast.

B. NOAA Solar Radiation Activity Observation and Forecast

Solar radiation, as observed by NOAA GOES-16 over the past 24 hours, was
below S-scale storm level thresholds.

              Jun 07  Jun 08  Jun 09
S1 or greater   10%     10%     10%

Rationale: There is a slight chance for S1 (Minor) or greater solar
radiation storms all three days primarily due to the flare potential
from Region 3327.

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 07 2023 1146 UTC.

Radio Blackout Forecast for Jun 07-Jun 09 2023

R1-R2           30%           30%           30%
R3 or greater   10%           10%           10%

Rationale: There is a chance for R1-R2 (Minor-Moderate) radio blackouts,
and a slight chance for R3 (Strong) or greater blackouts all three days
primarily due to the flare potential from Region 3327.

Extended Space Weather Discussion:

Solar Activity

.24 hr Summary...
Solar activity reached moderate levels with an M4.7 flare from Region
3327 (S14E34, Dki/beta-gamma-delta) at 07/1146 UTC. The most interesting
regions were 3323 (S08W20, Eki/beta-gamma) and 3327. Region 3323
underwent notable decay, but maintained its mixed polarity signature.
Region 3327 spread out further east-west and developed a delta
configuration in the trailing spot field. The region was also the
primary source of occasional C-class flares, to include a C7.1 at
07/0645 UTC which had an associated Type II sweep (543 km/s) and CME off
the SE. This event is being analyzed at the time of this writing. No
other potentially Earth-directed CMEs were observed.

Solar activity is expected to be low, with a chance for M-class (R1-R2,
Minor-Moderate) flares and a slight chance of an X-class flare
(R3-Strong) through 09 Jun.

Energetic Particles

.24 hr Summary...
The greater than 2 MeV electron flux was at normal to moderate levels
and the greater than 10 MeV proton flux remained at background levels.

The greater than 2 MeV electron flux is expected to be at moderate
levels through 09 Jun and the greater than 10 MeV proton flux is
expected to be at background levels. There is a slight chance of a S1
(Minor) event all three days.

Solar Wind

.24 hr Summary...
Solar wind parameters were near background levels. Total field strength
was at 5 nT and Bz briefly reached -5 nT but was otherwise in a neutral
or northward orientation. Wind speeds decreased to near 325 km/s. The
phi angle was predominately positive.

Ambient conditions are most likely for 07 Jun. The periphery of the CME
from 04 Jun is forecast to affect Earth on 08 Jun, with effects
lingering into 09 Jun.


.24 hr Summary...
The geomagnetic field was quiet.

Mostly quiet levels are anticipated on 07 Jun. Unsettled to active
levels are forecast on 08-09 Jun with the 04 Jun CME proximity.

  • 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.
    Insent your Mag's Unique ID.
