The case of the relativistic particles solved

Encircling Earth are two enormous rings — called the Van Allen radiation belts — of highly energized ions and electrons. Various processes can accelerate these particles to relativistic speeds, which endanger spacecraft unlucky enough to enter these giant bands of damaging radiation. Scientists had previously identified certain factors that might cause particles in the belts to become highly energized, but they had not known which cause dominates.

Found: Missing Mexican Aurora

The Carrington Event struck on September 1, 1859, when a coronal mass ejection erupted from the Sun and struck Earth. The resulting geomagnetic storm set off a vast display of the Aurora Borealis, the Northern Lights, on September 2 that was seen as far south as Cuba and Hawaii. Those low latitudes suggest it should have been seen in Mexico as well, but little has been known about what people saw there – until now.

South Napa Earthquake linked to summer groundwater dip

Recently there were a number of news articles released on the August 24, 2014 South Napa earthquake.  Below are a number of links to these articles.  The CCRA thanks Meredith Kraner, a graduate student at the University of Nevada, Reno, and lead author of the new study for her work and links.

This is AGU’s report. The most detailed and accurate.

NO6W’s WORLD of SDR

Glen has been a master tinkerer in electronics all of his life and I have found him to be a go to Elmer when I wanted to know something about something.  Recently he approached me to see if the CCRA would mind posting some of his thoughts and links regarding Software Defined Radio (SDR).    I jumped at the offer and have copied what he sent to me.  You will find his CCRA page under the DIGITAL section of the CCRA Website with the title, “NO6W’s WORLD of SDR.”   My hope is he will update his information and continue to share his knowledge with us in the future.
