Scale levels).

Rationale: G1 (Minor) geomagnetic storms are likely on 01 Dec due to CH
HSS influences.

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.

Extended Space Weather Discussion:

Solar Activity

.24 hr Summary...
Solar activity was very low. Regions 3151 (S16W73, Cso/beta) and 3152
(N27W05, Bxo/beta) were stable and in decay.

A filament/prominence eruption occurred from along the southeast limb
beginning near 28/2049 UTC as seen in GOES/SUVI 304A imagery. This event
was modeled and determined to be a clear miss.

Solar activity is expected to be very low with a chance for C-flares
through 01 Dec.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux reached moderate levels. The
greater than 10 MeV proton flux was at background levels.

The greater than 2 MeV electron flux is expected reach high levels on 29
Nov with elevated solar winds and the greater than 10 MeV proton flux is
expected to persist at background levels.

Solar Wind

.24 hr Summary...
Earth remained under the influence of a positive polarity CH HSS. Solar
wind speeds started the day around 540 km/s and increased to near 660
km/s. Total field strength peaked at 9 nT and Bz deviated southward
early and late in the day, reaching a maximum southward deviation of -10
nT at 28/0033 UTC.

An enhanced solar wind environment is expected to last through 01 Dec
due to the influences of multiple positive polarity CH HSSs.


.24 hr Summary...
The geomagnetic field reached G1 (Minor) geomagnetic storming levels
while under the influence of a positive polarity CH HSS.

Unsettled to active conditions are expected through 29 Nov with ongoing
CH HSS (+) activity, along with the anticipated arrival of another
positive polarity CH HSS. Isolated G1 (Minor) storming is also possible.
A third CH HSS is forecast to arrive on Day 3 (01 Dec) with stronger
winds, prompting a G1 (Minor) geomagnetic storm Watch.

  • 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.
