Extended Three Day Forecast:

A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 3 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Mar 04-Mar 06 2026 is 4.67 (NOAA Scale
G1).

Rationale: Isolated G1 (Minor) geomagnetic storms are possible on 04 Mar
due to CH HSS influences.

B. NOAA Solar Radiation Activity Observation and Forecast

Solar radiation, as observed by NOAA GOES-18 over the past 24 hours, was
below S-scale storm level thresholds.

Extended Space Weather Discussion:

Solar Activity

.24 hr Summary...
Solar activity continued at low levels with isolated C-class flaring.
Regions 4381 (N0830, Eao/beta) and 4384 (N10E53, Eho/beta) remained the
primary drivers of activity. The largest event of the period was a C2.9
flare from Region 4381 at 03/0030 UTC. Region 4384 continues to rotate
further onto the disk, but foreshortening still hinders a definitive
characterization of its magnetic complexity. Region 4378 (N15W07,
Cho/beta) showed some new flux emergence but remained mostly inactive.
Region 4383 (N15W41, Axx/alpha) simplified into a unipolar group
following the loss of its trailing spots, while Region 4380 (S21E05)
decayed to plage. No Earth-directed CMEs were observed in available
coronagraph imagery.

.Forecast...
Solar activity is expected to be at low levels, with a chance for
isolated M-class activity (R1-R2/Minor-Moderate) through 06 Mar.


Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux reached high levels with a peak of
7,430 pfu observed at 03/0005 UTC. The greater than 10 MeV proton flux
remained at background levels.

.Forecast...
The greater than 2 MeV electron flux is expected to reach high levels on
04-06 Mar. The greater than 10 MeV proton flux is expected to continue
at background levels through 06 Mar.


Solar Wind

.24 hr Summary...
Solar wind parameters reflected the onset of a positive polarity coronal
hole high-speed stream (+CH HSS). Solar wind speed increased to ~450
km/s. Total magnetic field (Bt) intensified, maintaining an average of
~10 nT. The North-South (Bz) component exhibited several southward
deflections, including two sustained southward orientations late in the
period where it reached a maximum deviation of -10 nT. The Phi angle
remained predominantly in a positive (away from the Sun) orientation,
except for those two periods of sustained -Bz.

.Forecast...
Solar wind parameters are expected to remain enhanced on 04 Mar due to
the ongoing influence of the positive polarity coronal hole high-speed
stream (+CH HSS). Residual enhancements are likely to persist on 05 Mar,
keeping conditions slightly above background levels, before another
enhancement is expected on 06 Mar with the onset of a negative polarity
coronal hole high-speed stream (-CH HSS).


Geospace

.24 hr Summary...
The geomagnetic field was at quiet to unsettled levels until the very
end of the reporting period, when G1 (Minor) storming conditions were
reached.

.Forecast...
The geomagnetic field is expected to be at unsettled to active levels on
04 Mar under +CH HSS influences, with a chance for an isolated period of
G1 (Minor) storming levels. Mostly unsettled levels are likely on 05 Mar
as the current streams influence wanes. A return to active and G1
(Minor) storming levels is likely on 06 Mar due to the onset of the
negative polarity CH HSS.

  • 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.
