Solar flares may head to Earth


Solar flares may head to Earth.

 

First Alert Meteorologist Allyson Raye interviews Dr. Alex Young about increased solar activity.  Young’s concern is with today’s technology that is more susceptible to damage from M- and X-class flares than was the equipment of the past.  A repeat of the 1859 “Carrington Event” which destroyed several telegraph stations and set buildings on fire, would be catastophic in the current century.  A huge flare could “fry” delicate solid state electronics in devices ranging from communications equipment to defense systems.  A series of X-class flares could render ATMs, switching systems, and even power plants inoperative.  Thankfully, NASA will soon orbit a MMS satellite which will give us some advanced warning of an impending CME or solar flare.  Is your amateur radio station protected from such an event?  My old Drake TR-4 transceiver still works.  I’m uncertain whether my Elecraft K3 would survive such an event.  At any rate, I disconnect all radio equipment and antennas when they aren’t in use.  Perhaps this step will save some of my radios.  It’s time to build a Faraday Cage.

45 years after Tranquility: One small step to a bright future | NASASpaceFlight.com


Forty-five years ago tonight, people across the world held their breaths as a hair-raising, heart-pounded descent occurred a quarter of a million miles away from Earth. At the Sea of Tranquility, on 20 July 1969, two humans succeeded in what many had considered impossible: landing and walking on the surface of another world.

I remember that night 45-years ago. I was stationed at Mather Air Force Base near Sacramento, California and watched this over a television set in my squadron’s briefing room.  I wished I could have been there, but as a “desk commando” (admin type), I was in no way qualified to be part of that historic mission.  I was so glad when the landing and departure were a success.  We were back in the space game again!  Those were the days.  Aloha de Russ (KH6JRM).

At Last! Amateur Astronomers Reboot 36-Year-Old ISEE-3 Spacecraft – NBC News

An ambitious project to resuscitate an abandoned spacecraft finally met with success Thursday as amateur astro-engineers took control of the International Su… (RT @NBCNewsTech: At Last!

Russ Roberts‘s insight:

A group of amateur radio operators, engineers, and astronomers has successfully regained control of the International Sun-Earth Explorer deep space probe.  Space College, the crowdfunded team that has been trying to “resuscitate” the long abandoned spacecraft ( it was launched in 1978), said Thursday that “we are now in command of the ISEE-3 spacecraft.”  In the weeks ahead, the volunteer team “will make an assessment of the spacecraft’s health and refine the techniques to fire its engines and bring it back to an orbit near Earth.” The final communications link between Earth and the ISEE-3 was provided by the Arecibo Radio Observatory in Puerto Rico.  Talk about a high-gain antenna!  Congratulations on this achievement.  Aloha de Russ (KH6JRM).
