Sota 20 meter

There is nothing special going on here. It’s rather quiet. I try to make one qso a day. But conditions are poor for several weeks now. Today I worked YU1FJK/P with CW on 20 meter. A SOTA station on YUFF119. I still work CW so now and then, because to maintain the skills. Yesterday 5000 km with 500 mW WSPR on 20 m. I did change the lay out of my Blogger template, hope you like it.

Jupiter's Auroras

Another instrument on Juno named "Waves" detected low-frequency. Unlike Earth, which lights up in response to solar activity, Jupiter makes its own auroras. The power source is the giant planet's own rotation. Although Jupiter is ten times wider than Earth, it manages to spin around 2.5 times as fast as our little planet. As any freshman engineering student knows, if you spin a magnet you've got an electric generator. And Jupiter is a very big magnet. Induced electric fields accelerate particles toward Jupiter's poles where the aurora action takes place. Remarkably, many of the particles that rain down on Jupiter's poles appear to be ejecta from volcanoes on Io. How this complicated system actually works is a puzzle. [Source:]
