The darker area at the center on the Earth-facing solar disc is a coronal hole--an area of weaker magnetic structure--from where faster solar wind is ejected out toward the Earth. The result? The faster solar wind interacts with the Earth's magnetosphere, creating geomagnetic activity including geomagnetic storms. Such storms degrade shortwave radio propagation.
This image (Oct. 31-Nov.2, 2018) reveals the coronal hole as it appears darker in this wavelength of extreme ultraviolet light--193 Angstroms. If these particles impact Earth's magnetosphere, they will likely generate aurora near the Earth's poles regions.

At the Pinnacle Arena in Lincoln, Nebraska, on 21 November 2018, four bands rocked the house: Ashes to New, Bad Wolves, Five Finger Death Punch, and Breaking Benjamin. I thought Five Finger Death Punch was the top performance! This is just a sampling of the light show work, as the audio is crap when you use a cell phone to record hard rock played at a very high volume!

Just signed the closing documents and now own a home in Lincoln, Nebraska. Moving now from Omaha. Here's a quick view of the four-season room, and then the back yard. Notice the natural antenna supports. Wire antennae might work, here.
In any case, I'm very happy with this property. More, to come, about this new QTH.

This move is from Omaha to Lincoln, Nebraska. No more two hours of commute time each day. No more excessive wear on my vehicle. Better area for my radio antenna farm. A room I am dedicating to video creation and production. Etc.
What is the proper (and most efficient) technique for creating Morse code by hand, using a manual Morse code key? Ham radio operators find Morse code (and the 'CW' mode, or 'Continuous Wave' keying mode) very useful, even though Morse code is no longer required as part of the licensing process. Morse code is highly effective in weak-signal radio work. And, preppers love Morse code because it is the most efficient way to communicate when there is a major disaster that could wipe out the communications infrastructure.
While this military film is antique, the vintage information is timeless, as the material is applicable to Morse code, even today.

In this video, I briefly introduce some of the type of signals I hear on my high-frequency (shortwave) amateur radio. Some of them are voice transmissions, and some are data. This video is simply the initial teaser for many videos to come. And, it served as an experiment in my editing two video sources and a third audio source, using Adobe Premier CC 2014 software.
