Extended Three Day Forecast:

A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 2 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Nov 15-Nov 17 2025 is 5.00 (NOAA Scale
G1).

Rationale: G1 (Minor) geomagnetic storms are likely over 16-17 Nov due
to the anticipated influence of a negative polarity coronal hole.

B. NOAA Solar Radiation Activity Observation and Forecast

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

Solar Radiation Storm Forecast for Nov 15-Nov 17 2025

              Nov 15  Nov 16  Nov 17
S1 or greater   20%     15%     10%

Rationale: There exists a slight chance for S1 (Minor) or greater solar
radiation storms over 15-17 Nov due to the eruptive potential from
Region 4274.

C. NOAA Radio Blackout Activity and Forecast

Radio blackouts reaching the R1 levels were observed over the past 24
hours. The largest was at Nov 14 2025 2012 UTC.

Radio Blackout Forecast for Nov 15-Nov 17 2025

              Nov 15        Nov 16        Nov 17
R1-R2           70%           60%           55%
R3 or greater   30%           25%           25%

Rationale: R1-R2 (Minor-Moderate) radio blackouts are likely, with a
chance for R3 (Strong), over 15-17 Nov due to the flare potential from
Region 4274.


Extended Space Weather Discussion:

Solar Activity

.24 hr Summary...
Solar activity was at moderate (R1-Minor) levels. Region 4274 (N25W80,
Ekc/beta-gamma-delta) produced two impulsive M1.3 flares at 14/2012 UTC
and 14/2131 UTC. Only minor changes were observed in seven numbered
regions across the visible disk.

An approximately 20 degree-long filament, centered near N30W38, was
observed lifting off the disk in GONG H-alpha imagery from ~14/1800-1930
UTC. Most of the ejecta was reabsorbed aside from a narrow CME observed
in LASCO/SOHO C2 imagery beginning at 14/1912 UTC. No Earth-directed
component is suspected.

Another eruption along a filament channel was observed in the SE
quadrant after ~15/0430 UTC. Subsequent coronagraph imagery contained a
slow-moving, southward oriented CME signature. Modelling of the ejecta
is ongoing.

.Forecast...
Solar activity is likely to reach moderate levels
(R1-R2/Minor-Moderate), with a chance for X-class (R3-Strong) activity
on 15-17 Nov, mostly due to the flare potential of Region 4274.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux were at moderate levels.

The greater than 10 MeV proton flux decreased below S1 (Minor) levels at
14/1325 UTC. Peak flux for the event was 16.5 pfu. The activity was
associated with an X4.0 flare from Region 4274 on 14 Nov.

.Forecast...
The greater than 2 MeV electron flux is expected to reach moderate
levels on 15-17 Nov.

There is a slight chance the greater than 10 MeV proton flux could see
additional S1 (Minor) solar radiation storm levels on 15-16 Nov while
Region 4274 continues to transit the W limb.

Solar Wind

.24 hr Summary...
Solar wind parameters reflected decreasing CME influence from the 11
Nov event. Solar wind speed were between 525-625 km/s. Total magnetic
field strength varied between 4-7 nT. No significant periods of
southward Bz were observed.

.Forecast...
Solar wind parameters are expected to continue to be enhanced but waning
through 15 Nov as CME influences diminish. Speeds in the 500-600 km/s
range are likely through 15 Nov. By mid to late on 16 Nov, a co-rotating
interaction region (CIR), preceding a negative polarity CH HSS, will
likely become geoeffective causing another enhancement in the solar wind
parameters over 16-17 Nov.

Geospace

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

.Forecast...
As solar wind speeds remain elevated yet waning, there is still a
decreasing chance for an isolated period of G1 (Minor) storm conditions
on 15 Nov. However, mostly quiet to unsettled levels are expected for
most of 15 Nov, continuing through late on 16 Nov until the anticipated
arrival of a CIR/CH HSS later in the UTC day. Active to G1 (Minor) storm
levels are likely on 16-17 Nov.

  • 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.
