The sun’s magnetic dynamo is weakening

Bruce Dorminey, writing on Forbes, says that astronomers now confirm that the Sun’s magnetic dynamo is likely to eventually disappear causing our star to lose its 11 year magnetic cycle

In fact, a billion years from now, they say, interplanetary spaceflight could become even more treacherous, since the Sun’s protective magnetic heliosphere would weaken or even disappear, leaving our solar system unshielded from incoming cosmic rays.

In a paper submitted to the journal Solar Physics, co-author Travis Metcalfe confirms that the Sun, a yellow dwarf (G-spectral type) star is indeed making a long term transition in its magnetic activity cycle.

Over the next one to two billion years, we have confirmed that the Sun’s magnetic cycle period will get longer before disappearing entirely.

Geomagnetic storm underway

A moderately strong G2-class geomagnetic storm is underway on May 27-28 as Earth moves through the wake of a CME that swept past our planet just hours ago.

High-latitude sky watchers should be alert for auroras, especially in the southern hemisphere where deepening autumn darkness favors visibility.

Came across this somewhat stealth multiband dipole antenna project.  Brought me back to when I was first licensed in the early ’80’s living in a condo residence I built one a bit more crudely designed then this one, but it did get me on the air with no complaints from my fellow neighbors at the time.  Had a lot of fun with it.
