Extended Three Day Forecast:

A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 7 (NOAA Scale
G3).
The greatest expected 3 hr Kp for Dec 02-Dec 04 2023 is 5.67 (NOAA Scale

Rationale: G1-G2 (Minor-Moderate) geomagnetic storms are expected on 02
Dec due to CME activity, and are likely on 04 Dec due to CH HSS
influences.

B. NOAA Solar Radiation Activity Observation and Forecast

Solar radiation, as observed by NOAA GOES-16 over the past 24 hours, was

Rationale: There is a slight chance for S1 (Minor) radiation storms over
02-04 Dec.

C. NOAA Radio Blackout Activity and Forecast

Radio blackouts reaching the R1 levels were observed over the past 24
hours. The largest was at Dec 01 2023 0439 UTC.

Extended Space Weather Discussion:

Solar Activity

.24 hr Summary...
Solar activity reached moderate levels due to an M1.1 flare at 01/0439
UTC from Region 3502 (N14W81, Cso/beta) and an M1.0 flare at 01/2120 UTC
from Region 3500 (S18W44, Ekc/beta-gamma). Slight decay was observed in
Region 3500. New Region 3509 (N10W50, Cri/beta) emerged in the NW
quadrant while the remaining spotted regions were relatively stable.

Other activity included a filament eruption centered near S30E58 that
began at 01/1344 UTC. A subsequent CME was observed off the SE limb at
01/1448 UTC. Modelling is underway, however it is unlikely to have an
Earth-directed component given its location. Also, an episode of EUV
dimming was observed near Region 3500 after the M1 flare at 01/2120 UTC,
however, not enough data is available for analysis at the time of this
writing.

.Forecast...
Solar activity is expected to remain low with a chance of M-class flares
and a slight chance of an isolated X-class flare on 02-04 Dec, primarily
due to the flare probability of Region 3500.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux was at normal to moderate levels,
while the greater than 10 MeV proton flux remained at background levels.

.Forecast...
The greater than 2 MeV electron flux is likely to be at moderate to high
levels on 02-03 Dec. A decrease to normal levels is likely on 04 Dec
with the arrival of a negative polarity CH HSS. There is a slight chance
of a S1 (Minor) event all three days due to the flare potential of
Region 3500.

Solar Wind

.24 hr Summary...
Solar wind parameters indicated the arrival of multiple CMEs from 27 and
28 Nov. The first arrival was at 30/2337 UTC. Solar wind speed increased
from approximately 335 km/s to near 440 km/s while total field increased
from 5 nT to 12 nT. The second arrival was at 01/0853 UTC, when solar
wind speed increased from approximately 406 km/s to near 510 km/s, and
total field increased from 15 nT to 25 nT. Total field continued between
13 nT and 28 nT through the rest of the period while solar wind speed
ranged from around 480 km/s to 560 km/s. The Bz component ranged from
+/-26 nT. Phi angle was variable.

.Forecast...
CME influence is expected to continue through midday on 02 Dec and
slowly recover to nominal conditions through 03 Dec. Early on 04 Dec, a
negative polarity CH HSS is expected to become geoeffective. Solar wind
speeds in the 600-700 km/s range is likely based on recurrence.

Geospace

.24 hr Summary...
The geomagnetic field was at active to G3 (Strong) storm levels due to
the arrival of multiple CMEs from 27 and 28 Nov.

.Forecast...
The geomagnetic field is expected to be at unsettled to G2 (Moderate)
storming, with a chance for G3 (Strong), on 02 Dec as CME effects
persist. Quiet to unsettled levels is expected on 03 Dec as activity
slowly wanes. Unsettled to G2 (Moderate) storm levels is likely again on
04 Dec as a negative polarity CH HSS is expected to become geoeffective.

  • 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.
