Earth-directed
CMEs were observed in available satellite imagery.

.Forecast...
Solar activity is expected to be very low over 01-03 Jun.

Energetic Particle

.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 values.

.Forecast...
The greater than 2 MeV electron flux is expected to continue at normal
to moderate levels 01-03 Jun and the greater than 10 MeV proton flux is
expected to remain at background levels.

Solar Wind

.24 hr Summary...
Solar wind parameters continued at nominal levels over the period with
solar wind speed ranging from 370-435 km/s. Total field ranged from 2-4
nT while the Bz component was between +/-3 nT. Phi angle was oriented in
a negative (towards) solar sector.

.Forecast...
Solar wind parameters are expected to be at or near nominal levels
through 03 Jun.

Geospace

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

.Forecast...
Mostly quiet levels are expected for 01-03 Jun under a nominal solar
wind regime.

  • 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.
