CME Sparks Minor
Geomagnetic Storm
High-latitude
auroras are possible tonight following a CME impact during the early
hours of June 5th (0511 UTC). It was not the big impact forecast models
predicted. So far, it has producd only a minor G1-class geomagnetic
storm. However, the storm could intensify as Earth moves through the
CME's magnetized wake.

Global
D Region Absorption
Conditions in the D-region of the ionosphere
have a dramatic effect on HF communications. The D-Region Absorption
map combines the effects of solar particles and
photons. Yellow to red colors on the map depict increasing signal
attenuation, where the bar chart at the right displays attenuation
versus frequency. Click the
thumbnail below for an animated map of D-Region Absorption:
The Aurora
Borealis
The aurora is not only beautiful to see but can have a
profound impact on HF and VHF radio propagation. For the HF operator,
auroras can result in a complete shut-down of propagation. However, on
VHF, auroras present interesting DX possibilities. Beam antennas are
very desirable and should be pointed north, towards the aurora. Signals
are reflected by “back-scatter” and will be distorted with a rough
buzz. SSB is the best voice mode to use, but copy can be difficult. CW
will have a rough buzzy sound but be perfectly copyable. Click the
thumbnail below for an animated map of aurora versus time:

A Propagation
Tutorial
The solar X-ray flux tracks solar activity and solar flares.
Solar
flux, which can vary from as low as 50 to as high as 300, influences
the level of ionization in the F2 region of the ionosphere, providing a
very good prediction of HF DX conditions. The higher the solar flux,
the better conditions will be for the higher HF frequencies and even 6
meters. However, the levels need to be maintained for some days to
allow ionization in the F2 layer to build up. A solar flux of 150
results in good HF band conditions, while levels of 200 and up can
provide great conditions.
Large X-ray flares on the sun can
increase the ionization of the D layer of the ionosphere (a lower
layer) on the sunlit side of the Earth, greatly attenuating or blocking
HF radio transmissions for up to a half hour. Solar flares often
produce Coronal Mass Ejections (CMEs) which, if Earth directed, can
lead to geomagnetic storms. Some large flares are also accompanied by
strong radio bursts that may interfere with other radio frequencies and
cause problems for satellite communication and radio navigation (GPS).
The
Planetary K-index is a measure of the magnitude of geomagnetic storms
and is an excellent indicator of disturbances in the Earth's magnetic
field. A level of 1 or 2 represents quiet geomagnetic conditions; a
reading of 3 or 4 may cause some propagation deterioration; 5 and 6 are
minor to moderate geomagnetic storms; and 7 to 9 are strong, severe,
and extreme storm conditions. Strong geomagnetic storms can trigger
Auroral displays and cause HF radio blackouts. Higher geomagnetic
activity also has the adverse effect of lowering maximum usable
frequencies, much like lower solar flux does.
For
best conditions, the solar flux should be above 150 for a few days with
the K index below 2. When these conditions are met, some good DX is
likely!
