Extended Space Weather Discussion:

Solar Activity

.24 hr Summary...
Solar activity was very low. Region 2759 (N28, L=263) remained spotless,
but active, producing low level flares early in the UTC day. There were
no Earth-directed CMEs observed in available coronagraph imagery.

.Forecast...
Solar activity is expected to be at very low levels on 08-10 Apr.

Energetic Particles

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

.Forecast...
The greater than 2 MeV electron flux is expected to continue at moderate
levels through 10 Apr. The greater than 10 MeV proton flux is expected
to continue at background levels.

Solar Wind

.24 hr Summary...
Solar wind parameters were at background levels. Solar wind speeds
averaged between 300-338 km/s throughout the day. Total field was 6 nT
or less, and Bz was mostly not of note until late in the UTC day when it
began to deviate southward in excess of -5 nT. Phi was negative.

.Forecast...
Solar wind parameters are likely to be at nominal levels through 9 Apr,
then become elevated late on 10 Apr with the arrival of a
polar-connected, negative polarity CH HSS. There is a slight chance for
an isolated disturbance on 8 Apr as a result of a smaller, negative CH
HSS that is near a geoeffective position. Otherwise background levels
are expected for much of the next 3 days until the main feature arrives
late on 10 Apr.

Geospace

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

.Forecast...
A small disturbance may briefly elevate levels to unsettled on 8 Apr,
otherwise quiet conditions are anticipated for most of the forecast
period. Day 3 (10 Apr) is expected to be mostly quiet until late in the
UTC day when levels are expected to become unsettled with the arrival of
a polar-connected, negative polarity CH HSS.

'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 (G15) Secondary (G14) 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.
