Extended Three Day Forecast:

A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 5 (NOAA Scale
G1).
The greatest expected 3 hr Kp for Feb 15-Feb 17 2026 is 5.67 (NOAA Scale
G2).

Rationale: Periods of G1-G2 (Minor-Moderate) geomagnetic storming are
expected on 15 Feb due to CIR effects and the onset of positive polarity
CH HSS influences. Weak CME enhancements are possible on 15 Feb as a CME
from 11 Feb passes in close proximity. Periods of G1 (Minor) storming
are likely on 16 Feb, with a chance for G2 (Moderate) storm periods,
under continued positive polarity 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.

              Feb 15  Feb 16  Feb 17
S1 or greater    1%      1%      1%

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

No radio blackouts were observed over the past 24 hours.

R1-R2           10%           10%           10%

Rationale: There is a slight chance for M-class (R1-R2/Minor-Moderate)
flares through 17 Feb.


Extended Space Weather Discussion:

Solar Activity

.24 hr Summary...
Solar activity remained at low levels. The largest flare of the period
was C1.3 at 15/0727 UTC from a plage region located near S13W46. Region
4377 (N06E52, Cro/beta) developed a few additional rudimentary spots,
while the remaining regions were stable or in decay. No Earth-directed
CMEs were detected in available imagery.

.Forecast...
Solar activity is expected to be at low levels, with a slight chance for
M-class (R1-R2/Minor-Moderate) flares through 17 Feb.

Energetic Particle

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

.Forecast...
The greater than 2 MeV electron flux is expected to reach moderate
levels on 15-16 Feb, before increasing to high levels on 17 Feb. The
greater than 10 MeV proton flux is expected to continue at background
levels through 17 Feb.

Solar Wind

.24 hr Summary...
Solar wind parameters were consistent with the onset of CIR effects
preceding positive polarity CH HSS influences.

Total magnetic field strength reached a peak of 15 nT. The Bz component
was sustained southward, by as much as -14 nT, between 14/1830-15/0120
UTC. Solar wind speeds steadily increased from a low of around 370 km/s
to a peak of around 700 km/s by the end of the period.

.Forecast...
The solar wind environment is expected to remain enhanced through 17 Feb
due to CIR influences, followed by the onset of positive polarity CH HSS
influences. Weak CME enhancements are possible on 15 Feb as a CME from
11 Feb passes in close proximity.

Geospace

.24 hr Summary...
The geomagnetic field reached G1 (Minor) storm levels in response to CIR
effects preceding positive polarity CH HSS influences.

.Forecast...
Periods of G1-G2 (Minor-Moderate) geomagnetic storming are expected on
15 Feb due to CIR effects and the onset of positive polarity CH HSS
influences. Weak CME enhancements are possible on 15 Feb as a CME from
11 Feb passes in close proximity. Periods of G1 (Minor) storming are
likely on 16 Feb, with a chance for G2 (Moderate) storm periods, under
continued positive polarity CH HSS influences. Active conditions are
likely on 17 Feb as CH HSS influences begin to wane.

  • 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.
