Extended Three Day Forecast:

A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 6 (NOAA Scale

The greatest expected 3 hr Kp for Nov 08-Nov 10 2025 is 6.33 (NOAA Scale
G2).

Rationale: G2 (Moderate) conditions are expected to persist through on
08 Nov with lingering CME/CH HSS influences, decreasing to active to G1
(Minor) levels on 09 Nov. Additional CME interactions are likely to
increase storm levels back to G1-G2 conditions on 10 Nov.

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.

              Nov 08  Nov 09  Nov 10
S1 or greater   15%     15%     15%

Rationale: Due to the complexity and history of Region 4274, there
remains a slight chance of an S1 (Minor) radiation storm through 10 Nov.

C. NOAA Radio Blackout Activity and Forecast

No radio blackouts were observed over the past 24 hours.

Rationale: R1/R2 (Minor-Moderate) radio blackouts are likely, with a
chance for isolated R3 (Strong) events on 08-10 Nov as the regions in
the eastern hemisphere remain active and magnetically complex.


Extended Space Weather Discussion:

Solar Activity

.24 hr Summary...
Solar activity was at low levels. Region 4274 (N24E09,
Ekc/beta-gamma-delta) remained the largest, most active, most
magnetically complex region on the visible disk, despite exhibiting
signs of weak decay and separation between its leader and trailer spots.
This region was responsible for multiple C-class flares, including a
C6.9/Sf flare (the largest of the period) at 07/1551 UTC. Regions 4276
(S17E45, Dai/beta-gamma) and 4277 (NS06E44, Dai/beta) both exhibited
growth during the period and added several C-class flares as well. The
remainder of the spot groups were relatively unchanged and inactive.

A couple of CMEs lifted off the northern quadrant of the disk and were
first visible in C2 imagery around 07/1248 UTC. Modelling and analysis
determined these CMEs to have a mostly northward trajectory, but a
flanking edge is likely to graze the Earth early on the 10th.

.Forecast...
Solar activity is likely to remain at moderate to high levels (R1/R2 -
Minor-Moderate), with a chance for isolated X-class (R3-Strong) flares,
on 08-10 Nov as the regions in the eastern hemisphere remain active and
magnetically complex.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux at geostationary orbit was at
normal to moderate levels. The greater than 10 MeV proton flux remains
at background levels.

.Forecast...
The greater than 2 MeV electron flux is expected to be at normal to
moderate levels on 08 Nov, with conditions likely reaching high levels
on 09-10 Nov following an increase in solar winds associated with the
CME/CH HSS.

Due to the complexity and history of Region 4274, there remains a slight
chance of an S1 (Minor) radiation storm through 10 Nov.

Solar Wind

.24 hr Summary...
Solar wind parameters reflected the likely combined residual CME effects
from the 03-04 Nov CMEs and negative polarity CH HSS influence. Total
field strength gradually decreased from ~12 nT to end the period near 4
nT. Bz was mostly northward until just before the turn of the UT day
when it switched southward, seeing a maximum deviation to near -10 nT.
Solar winds began the period just under 800 km/s before beginning a
steady decline to end of period speeds around 600 km/s. Phi was
variable, hovering in a near-neutral orientation for most of the period.

.Forecast...
Solar wind parameters are expected to remain slightly enhanced through
10 Nov with lingering CME/CH HSS influences. Additional enhancements
are likely on 10 Nov with the possible grazing of the 07 Nov CME.

Geospace

.24 hr Summary...
The geomagnetic field reached G2 (Moderate) storm levels due to the
combined effects of the aforementioned CME and CH HSS.

.Forecast...
G2 (Moderate) conditions are expected to persist through on 08 Nov with
lingering CME/CH HSS influences, decreasing to active to G1 (Minor)
levels on 09 Nov. Additional CME interactions are likely to increase
storm levels back to G1-G2 conditions on 10 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.
  • 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.
