The greatest observed 3 hr Kp over the past 24 hours was 7 (NOAA Scale

The greatest expected 3 hr Kp for Mar 22-Mar 24 2026 is 6.67 (NOAA Scale

Rationale: G2 (Moderate) geomagnetic storming is likely on 22 Mar due to
waning CME influences and the anticipated onset of CH HSS effects.
Isolated periods of G1 (Minor) geomagnetic storming are likely on 23 Mar
as CH HSS effects continue. Unsettled to active levels are expected to
prevail on 24 Mar.

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.

Rationale: No S1 (Minor) or greater solar radiation storms are expected.
No significant active region activity favorable for radiation storm
production is forecast.

C. NOAA Radio Blackout Activity and Forecast

Rationale: Solar activity is expected to be very low with a chance for a
C-class flares and a slight chance for an M-class flare on days one,
two, and three (22 Mar, 23 Mar, 24 Mar).


Extended Space Weather Discussion:

Solar Activity

.24 hr Summary...
Solar activity was at low levels with C-class flare activity observed
from Region 4399 (S17E75, Hax/alpha). Region 4397 (N16E20, Axx/alpha)
showed signs of decay in its trailing spot. New Regions 4400 (S13W19,
Bxo/beta), 4401 (N24E72, Hax/alpha) and 4402 (N14E75, Hax/alpha) were
numbered this period.

No Earth-directed CMEs were observed in available coronagraph imagery.

.Forecast...
Solar activity is expected to be very low with a chance for a C-class
flares and a slight chance for an M-class flare on days one, two, and
three (22 Mar, 23 Mar, 24 Mar).

Energetic Particle

.24 hr Summary...
Electrons greater than 2 MeV at geosynchronous orbit were at normal to
moderate levels. The greater than 10 MeV proton flux continued at
background levels.

.Forecast...
The greater than 2 MeV electron flux will likely reach high levels on 22
Mar and remain at high levels through 24 Mar. The greater than 10 MeV
proton flux is expected to continue at background values.

Solar Wind

.24 hr Summary...
Solar wind parameters reflected CME influences. Solar wind speed reached
a peak of 600 km/s at 22/1000Z. Total IMF reached 38 nT at 21/1532Z. The
maximum southward component of Bz reached -27 nT at 20/2105Z. Phi varied
between positive and negative sectors.

.Forecast...
The solar wind environment is expected to remain enhanced through the
forecast period. CME effects are expected to begin to wane by early on
22 Mar before an additional disturbance due to recurrent, negative
polarity CH HSS influences arrive and continue through 24 Mar.

.24 hr Summary...
The geomagnetic field was at mostly unsettled to G1 (Minor) levels
before reaching G3 (Strong) levels late in the period.

.Forecast...
G2 (Moderate) to G3 (Strong) geomagnetic storming is likely on 22 Mar
due to waning CME influences and the anticipated onset of CH HSS
effects. Isolated periods of G1 (Minor) geomagnetic storming are likely
on 23 Mar as CH HSS effects continue. Unsettled to active levels are
expected to prevail on 24 Mar.

  • 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.
