Extended Space Weather Discussion:

Solar Activity

.24 hr Summary...
Solar activity was at low levels. Only C-class flares were observed from
Regions 4323 (S16W63, Dso/beta), 4324 (N25W16, Cso/beta), 4330 (S16,
L=275), and 4336 (S09E59, Eso/beta). Slight decay was observed in
Regions 4323, 4325(S08W71, Eko/beta), and 4333 (S10W46, Cro/beta). The
rest of the spot groups were relatively stable.

Other activity included an approximate 5 degree filament eruption
centered near S18W40 at 05/1854 UTC. A likely associated CME was
observed off the SW limb at 05/1857 UTC in SOHO/LASCO C2 imagery.
Modeling efforts resulted in a miss behind Earths orbit.

.Forecast...
Solar activity is expected to be low with a chance for M-class flares
(R1-R2, Minor-Moderate), and a slight chance for isolated X-class
flares (R3-Strong) over 06-08 Jan.

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 was at background levels.

.Forecast...
The greater than 2 MeV electron flux is expected to continue at normal
to moderate levels on 06-08 Jan. There is a slight chance for S1 (Minor)
solar radiation storms through 08 Jan.

Solar Wind

.24 hr Summary...
Solar wind parameters were at nominal levels. Total field strength was
between 5-7 nT. The Bz component was at benign values. Solar wind speed
was mostly below 400 km/s. Phi was negative.

.Forecast...
Solar wind parameters are expected to be at or near nominal levels on
06-08 Jan.

Geospace

.24 hr Summary...
Geomagnetic activity was at quiet to unsettled levels.

.Forecast...
The geomagnetic field is expected to be mostly quiet on 06-08 Jan.

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.

AF Index (Experemental) AF Community Activity (Hits)
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.

SWPC Kp (Observation)
SWPC Kp (Prediction) GeoSpace Kp (Prediction) Wing Kp (Legacy : Date < 22/06/18)
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.

Northern Hemisphere (Aurora Borealis) Southern Hemisphere (Aurora Australis)
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.
Show ACE (When enabled the forecasting / timeshift feature will be disabled)
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.

Primary Secondary Variation (Pri - Sec)
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.
