The Australian Space Forecast Centre issued a Geomagnetic
Disturbance Warning on December 29 at 0010 UTC. "A recurrent equatorial
coronal hole will soon reach geoeffective
location on the solar disk. The size of the current coronal hole is
relatively larger compared to its characteristics during the
previous rotation. The co-rotating interaction region and subsequent
high speed streams associated with the coronal hole is expected to
affect Earth from late 30 December. Auroras may be visible on the
local nights of 30 and 31 December in Tasmania and possibly from the
coastline of Victoria."

Devices Could Make Motorist Hang Up and Drive:

Wouldn't it be great if you could switch off the cellphone signal to the
guy who's gabbing on his phone while driving distractedly in front of you?
A group of U.S. amateur radio fans were close to developing that "hang up"
device in the 1990s, inspired by military technology during the first Gulf
War. When George H. W. Bush ordered an offensive on Iraq that lasted 100
hours in February 1991, all of America watched as 42 Scud missiles were
fired into Israel over a period of several weeks. The only effective
defenses to these fatal attacks were electronics that sensed incoming Scuds
and launched Patriot warhead-seeking missiles, and it wasn't very
successful. But the efforts that technicians from arms maker Raytheon
expended to help our military industry protect Israel were legendary. About
this same time we were noticing folks driving at congestion-inducing 50 mph
speeds on I-696 and on other jam-sensitive roads in the normally safe,
free-flowing left lanes. Almost always, this happened in cars driven by
people engaged with their new cellphones. The drivers were rarely ticketed.
Frustrated by this, a group of amateur radio experts around the U.S.
wondered if the same efforts used to intercept Scud missiles could help
reduce cell phone-related distracted driving.

So, do we really understand our hobby to the
point where we can make that explanation? I
think not, more to the point, neither do you.
The Internet and the airwaves are full of
explanations of how things in Amateur Radio
work and many of them disagree with each
other, sometimes loudly.
