Good Evening,
There were moments of sunshine this week. Mostly sun beams just
after sunrise and just before sunset. The rest of the time it was
cloudy, foggy and rainy. I saw a movement outside this window
yesterday. Not a bird, it was a vole. It spent about fifteen minutes
harvesting lichen from a fir trunk. Food or bedding material? Probably
both, lichen is nutritious, deer love it. It also insulates.
The sun is covered. Mostly by one large sunspot group. It was
spewing ions as it passed over the sun's limb but has been quiet since
then. Lots of energy is tied up waiting to burst. It will take another
four or five days before it is not aimed in our direction. Currently
solar flux is high; we are in a stream of solar wind.
Please join us on (or near):
14050 kHz at 2300z Sunday (3 PM PST Sunday)
7047 kHz at 0100z Monday (5 PM PST Sunday)
73,
Kevin. KD5ONS

I have taught my fireworks they are matter: they have mass, and take up
space. The former lets them be affected by gravity fields. The latter
counts when they hit either the earth or the moon in this simulation:

My next step is to give them electrical charge and teach them about
magnetic fields. Those particles which hit the earth will interact in
the ionosphere. The Lorentz force equation will change their
velocities. Ions moving around in a magnetic field create an electric
field. Maybe one day I'll take that step too.
