Extended Space Weather Discussion:

Solar Activity

.24 hr Summary...
Solar activity continued at low levels, characterized by less frequent
C-class flaring compared to the previous period. Regions 4381 (N08E42,
Eao/beta) and 4384 (N10E67, Ehi/beta) remained the primary drivers of
activity. Region 4384 rotated further onto the disk, and while
foreshortening still hinders definitive magnetic analysis, additional
trailing spots were observed rotating into view. This region produced
the largest event of the period, a C4.5 flare at 02/0438 UTC.

Region 4378 (N15E13, Cho/beta) transitioned from an H- back to a C-group
as trailing spots exhibited transitory behavior, though the lead spot
remained stable in size and the region was inactive. Region 4380
(S21E25, Bxo/beta) decayed into simple, non-penumbral spots. Region 4383
(N15W23, Bxo/beta) remained inactive and stable in overall extent,
despite minor spot flux variations (disappearing and reappearing) within
its positive polarity pole.

For eruptive activity, two filament eruptions occurred: a 20-degree
filament near N53E28 (02/0230 UTC) and an 11-degree filament near N10W68
(02/1000 UTC). The northern eruption was first observed in LASCO C2
imagery at 02/0936 UTC, while the western eruption appeared in C2
imagery at 02/1036 UTC. Modeling indicates no Earth-directed components
from either event, and no other CMEs of interest were observed in
available coronagraph imagery.

.Forecast...
Solar activity is expected to be at low levels, with a chance for
isolated M-class activity (R1-R2/Minor-Moderate) through 05 Mar.


Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux reached high levels with a peak of
14,495 pfu observed at 02/1810 UTC. The greater than 10 MeV proton flux
remained at background levels.

.Forecast...
The greater than 2 MeV electron flux is expected to reach high levels on
03-05 Mar. The greater than 10 MeV proton flux is expected to continue
at background levels through 05 Mar.


Solar Wind

.24 hr Summary...
Solar wind parameters were indicative of an ambient solar wind regime.
Solar wind speeds continued to trend downward, reaching around 300 km/s
by periods end. Total magnetic field (Bt) remained steady, hovering
between 4 and 6 nT, while the North-South (Bz) component fluctuated
between +5/-5 nT. The Phi angle stabilized into a predominantly positive
(away from the Sun) orientation for most of the period, marking a clear
transition following the previous periods sector instability.

At 02/2319 UTC, a small transient may have arrived: there is a small
discontinuity in the wind speed (sudden jump to ~350 km/s), Bt (sudden
small increase to 8 nT) and phi angle, with a simultaneous scramble and
following slight rotation of the magnetic field components.

.Forecast...
Enhancements in solar wind conditions are possible 03-04 Mar due to the
onset of a positive polarity coronal hole high-speed stream (+CH HSS). A
return toward a more nominal, ambient regime is likely by 05 Mar.


Geospace

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

.Forecast...
The geomagnetic field is expected to reach unsettled levels on 03-04 Mar
as +CH HSS influences begin with a chance for isolated active periods.
Conditions are likely to return to predominantly quiet to unsettled
levels by 05 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.
