Extended Space Weather Discussion:

Solar Activity

.24 hr Summary...
Solar activity continued at low levels. Region 4465 (N08W04, Cao/beta)
developed a few rudimentary leader spots, and new Region 4468 (N10E46,
Cro/beta) was numbered this period. The remaining regions were either
stable or in decay. The strongest flare of the period was a C2.5/Sf at
13/1309 UTC associated with a filament eruption near S21W73. The
subsequent CME, first observed in LASCO C2 imagery off the SW at 13/1326
UTC, is expected to miss Earth.

.Forecast...
Solar activity is expected to remain at low levels through 16 Jun, with
a slight chance for M-class (R1-R2/Minor-Moderate) flares.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux reached high levels, with a peak
flux of 1,519 pfu. The greater than 10 MeV proton flux remained at
background levels.

.Forecast...
The greater than 2 MeV electron flux is likely to reach high levels on
14-16 Jun. The greater than 10 MeV proton flux is expected to continue
at background levels through 16 Jun.

Solar Wind

.24 hr Summary...
Solar wind parameters reflected the continued influence of a negative
polarity CH HSS, with some lingering CME enhancements early in the
period. Total field strength reached 7 nT, and the Bz component varied
between +/-5 nT. Solar wind speeds gradually decreased from a peak near
625 km/s early in the period to a low of around 475 km/s by the end of
the period.

.Forecast...
The solar wind environment is expected to remain mildly enhanced over
14-15 Jun under continued, but waning -CH HSS influences. An additional
enhancement is likely on 16 Jun due to the anticipated glancing-blow
arrival of a CME from 12 Jun.

Geospace

.24 hr Summary...
The geomagnetic field was at mostly quiet to unsettled levels, with an
isolated active period, under -CH HSS and CME influences.

.Forecast...
The geomagnetic field is expected to be at quiet to unsettled levels,
with a chance for active conditions, on 14-15 Jun as -CH HSS influences
slowly diminish. Periods of active conditions are likely on 16 Jun due
to the anticipated glancing-blow arrival of a CME that left the Sun on
12 Jun.

  • 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.
