C. NOAA Radio Blackout Activity and Forecast

No radio blackouts were observed over the past 24 hours.

R3 or greater   10%           10%           10%

Rationale: Isolated R1/R2 (Minor/Moderate) radio blackouts are likely,
with a slight chance for isolated R3 (Strong) events through 11 June,
primarily due to the flare potential exhibited by Regions 4456 (N17W61,
Dai/beta), 4462 (N15W07, Dsi/beta), 4464 and 4465.

Extended Space Weather Discussion:

Solar Activity

.24 hr Summary...
Solar activity remained at low levels with numerous C-class flares
observed from Regions 4456 (N18W67, Esi/beta), 4464 (S12E17, Dsi/beta)
and 4465(N09E63, Dsi/beta-gamma). Most of the activity originated from
Region 4465 with the largest a C4.5/Sf observed at 09/0423 UTC. There
are seven active regions on disk, most of them remained stable or showed
some decay in area. Region 4464 indicated some minor enhancements among
its intermediate spots. Departed Region 4455 (N15, L=092) also produced
some weak C-class activity.

No new Earth-directed CMEs were observed in available coronagraph
imagery.

.Forecast...
Isolated M-class flares are likely, with a slight chance for X-class
flares, through 11 June primarily due to the flare potential exhibited
by Regions 4456, 4462 (N16W14, Dsi/beta), 4464 and 4465.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels with a peak flux of 1,310 pfu at 08/1340 UTC. The greater
than 10 MeV proton flux remained at background levels during the period.

.Forecast...
The greater than 2 MeV electron flux levels at geosynchronous orbit are
likely to continue reaching high levels through 10 June, returning to
moderate-low levels on 11 June. The greater than 10 MeV proton flux is
expected to remain at background levels through 11 June.

Solar Wind

.24 hr Summary...
Solar wind parameters suggested a slow decline in the wind environment.
Solar wind speeds decreased from about 450 km/s to near 400 km/s, while
the total Interplanetary Magnetic Field (IMF) strength showed a slight
oscillation around 5nT. At about 09/0954 UTC, The IMF increased sharply
to 10 nT. The Bz component oscillated between -5 nT to +3 nT, and
further reached S to -5 nT. The Phi angle remained mostly in the
positive sector during the day.

.Forecast...
Analysis of the solar wind parameters, along with the suprathermal ions
and electrons data from instruments at L1, suggested that the 06 June
CME glancing passage near Earth already occurred on 08 June, reducing
our confidence in further impacts on the next days. Therefore,
background solar wind is expected until 11 June, when a -CH HSS is
anticipated to become geoeffective.

Geospace

.24 hr Summary...
Geomagnetic field activity was at quiet levels during the past 24 hrs.

.Forecast...
The geomagnetic field is expected to be at quiet to active levels on 09
June, quiet to unsettled levels on 10 Jun, and active levels on 11 June
(due to anticipated -CH HSS effects).

'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.

AF Index (Experemental) AF Community Activity (Hits)
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.

Northern Hemisphere (Aurora Borealis) Southern Hemisphere (Aurora Australis)
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.
