Summary
For the 8 day period from Monday, October 21st through yesterday, October 28th.
The average solar flux was 215, up 48 points from the previous week,
with a weekly high of 255 on Monday, October 28th, following
a low of 164 on October 21st.
The average sunspot count was 171, up 37 from last week,
peaking at 288 on Monday, October 28th after a
weekly low of 104 on October 23rd.
The Planetary K-index weekly average was 3.2 with a
maximum of 4.7 on Monday, October 28th, resulting
in generally quiet geomagnetic conditions.
Solar flare activity since October 22nd has been high with 11
major flares, the largest of which was a major X 3.3 event on Thursday,
October 24th.

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:

Protons Are Raining Down on Earth
For the 3rd day in a row, energetic protons are raining down on Earth. It's an S2-class radiation storm. The protons were accelerated by X-class solar flares on Oct. 24th and 26th. As a result of the storm, a shortwave radio blackout is underway inside the Arctic Circle,
and cameras on spacecraft are being fogged. Indeed, most of the
speckles in the SOHO coronagraph movie highlighted below are solar
protons hitting the camera. This could continue for at least another 24
hours.

Giants on the Sun
"Today
we have three big things on the sun: A gigantic string of big and
active sunspots, a large sunspot just coming into view, and a
magnificent solar prominence," reports Maximilian-Vlad Teodorescu of
the Institute of Space Science in Magurele, Romania. He photographed
them all on Oct. 29th:
"All are far above the usual size of sunspots and prominences," says Teodorescu. "What a wonderful solar maximum!"
Three of the sunspots Teodorescu photographed pose a threat for
very strong solar flares: 3869, 3872, 3874 have 'beta-gamma-delta'
magnetic fields in which opposite polarities are bumping together in dangerous proximity. NOAA forcasters estimate a 75% chance of M-class solar flares and a 30% chance of X-flares during the next 24 hours.

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!
