Earth dodges a cosmic bullet — for now

Solar flares and related phenomena could cause tremendous damage to the Earth’s electric grids, writes Don Lincoln Read the full story

(CNN) Mother Nature has had a hectic past couple of weeks of hurricanes, an earthquake, wildfires and flooding. But while our attention has been turned to these humanitarian crises, Earth ducked a cosmic bullet the likes of which could have crippled human technological civilization.

Over the last week or so, the sun has experienced a series of solar flares, including the most energetic one in a decade. A solar flare occurs when magnetic energy in the vicinity of a sunspot is released, resulting in a bright spot on the sun that takes place over a time scale of perhaps 10 minutes — or even less.

[…]While solar flares can interfere with satellites, an even more dangerous phenomenon is called a coronal mass ejection (or CME). CMEs often accompany a flare and occur when some of the sun’s highly ionized material is ejected into space. Because a CME consists of matter and not the electromagnetic radiation of a flare, it can take a day or even more to travel from the sun to the Earth. Indeed, last week’s flares were accompanied by a CME, but it didn’t hit the Earth with its full fury.

If a CME happens to be aimed directly at Earth, the ionized particles can slam into the magnetic field that surrounds the Earth and distort its shape, a process called a geomagnetic storm. That’s when things can get dangerous. Moving magnetic fields can induce electrical currents on the Earth’s surface and damage equipment.

In 1989, a CME hit the Earth and knocked out power in Quebec and the northeast United States for nine hours. And in 1859, an enormous CME hit the Earth. Called the Carrington Event, after Richard Carrington, who observed and recorded it, this geomagnetic storm caused telegraph pylons and railroad rails to spark, shocked telegraph operators and was responsible for auroras visible at least as far south as Havana, Cuba, with some claims of auroras being observed near the Earth’s equator.

[…]A report by Lloyd’s of London in 2013 estimated that the damage to the US grid from a repeat of the Carrington Event would be in the range of $0.6-$2.3 trillion dollars and would require four to 10 years to repair.

“The total U.S. population at risk of extended power outage from a Carrington-level storm is between 20-40 million, with durations of 16 days to 1-2 years,” the Lloyd’s report said.[…]

EMP article incoming…

One additional note: I’m currently in the process of writing a lengthy article about how to protect your gear from an EMP (Electromagnetic Pulse) emanating from an event like this. In the past two weeks, I’ve had an uptick in inquiries about this, so I thought it best to consult an expert and produce a post. I’ll hopefully have this article published within a week or so. I’ll post it with the tag: EMP.

Radio: “One of history’s most important inventions”

(Source: CNN)

There are few more important inventions in the history of the world than the radio.

While in recent years it may have become less popular than television or the internet, it could be argued that the radio was the first electronic gadget to play a prominent part in people’s lives.

Radio is where the world first heard Britain declare war on Germany, where Orson Welles accidentally fooled the public into believing a real alien invasion was under way in his “War Of The Worlds” serial and where young people first heard Billy Haley’s “Rock Around The Clock,” spreading popular music around the world.

But it is not just an aural medium. Like all important pieces of technology, design has had an essential part to play in its evolution.[…]

It turns out that radio still gets results.

Amid all the changes in television and digital media, a report from Nielsen released Tuesday found that radio’s nationwide audience reached an all-time high during the second quarter of 2015.

According to Nielsen, about 245 million Americans ages 12 and up used radio during the that span.

It was a continuation of an upward trend for radio, which has seen its national audience swell to record highs in each of the last two years. In the first quarter of this year, radio eclipsed television as the country’s top reaching medium.

CNN to stop broadcasts in Russia

CNN to stop broadcasting in Russia at end of year

Text of report by Russian state-owned TASS news agency (formerly ITAR-TASS)

Moscow, 10 November. Roskomnadzor [the Russian Federal Service for Supervision in Telecommunications, Information Technology and Mass Communications] has nothing to do with the stopping of broadcasts by the TV news channel CNN International on Russian cable networks, Roskomnadzor spokesman Vadim Ampelonskiy has told TASS.

“You should ask CNN’s shareholders about the reasons why the channel is stopping broadcasts,” Ampelonskiy said.

A source who is familiar with CNN’s business in Russia told TASS that CNN is stopping broadcasts on Russian cable networks for commercial reasons.

CNN is distributed in Russia on the cable and satellite networks of operators of subscription television such as Akado, Vympelkom, NTV and others.

The fact that CNN will stop broadcasting on cable networks in Russia from 31 December 2014 is stated in a letter from Turner Broadcasting System Europe (CNN’s owner), a copy of which TASS has. “With this letter we inform you that Turner is stopping the distribution of the CNN International television channel on the territory of the Russian Federation from 31 December 2014,” the letter says. The letter does not give the reasons for the decision. Turner Broadcasting System’s managing director in the CIS, Tatyana Kalita, declined to comment.

Akado and Vympelkom confirmed to TASS that they had received the letter. “Yes, we received the letter. We hope that next year the channel will broadcast on the territory of Russia again,” Vympelkom’s press service said.

Jonathan also points out this article, which links the cessation of CNN broadcasts to a new law Putin has enacted:

CNN, the cable news channel owned by Time Warner, will stop broadcasting in Russia after a new law was passed that limits foreign ownership in media companies.
Time Warner’s Turner Broadcasting division said it hopes to resume broadcasting eventually, according to an e-mailed statement. The move was first reported by Russia’s Vedomosti newspaper. CNN’s Moscow bureau operations are unaffected, according to the statement.

“Turner International is assessing its distribution options for CNN in Russia in light of recent changes in Russian media legislation,” Turner wrote in the statement. “We are bringing our existing distribution relationships to an end while we do that. We hope to re-enter the market in due course, and will notify our partners of any update about resuming these services.” 

Last month, President Vladimir Putin signed a law that requires Russian media with foreign owners to reduce non-Russian ownership to 20% by the end of 2016.

Coded message from WWII carrier pigeon structured like numbers station communiqué

The message contains the all-too-familiar 5 character groupings we’re used to hearing in numbers station broadcasts

This news story about a recently discovered WWII carrier pigeon message has been floating around the Internet over the past few days.

(Source: CNN)

Not even the British spy agencies that inspired James Bond can solve the mystery of a secret World War II message recently found on the skeleton of a carrier pigeon in a house chimney.

The meaning of the encoded message apparently died about 70 years ago with the wayward pigeon that David Martin found in his smokestack in Bletchingley, Surrey County, England.

Martin recently discovered the bird’s remains with the surprisingly intact message inside a small red canister attached to a leg bone.

[…]Hand-written on a small piece of paper labeled “Pigeon Service,” the note consists of five-letter words. Those words don’t make sense: The jumble begins with “AOAKN” and “HVPKD.” In all, the message consists of 27 five-letter code groups.

Indeed, the only hope the UK intelligence agency, the GCHQ, stands in deciphering the message (click here to see the full message) would be to find the appropriate, specific decipher key. Most likely, this message–like numbers station (a.k.a. spy numbers) messages–was a one-time communiqué, with a one-time decipher key. This type of encryption is incredibly effective as they provide little to no context for deciphering.

But again, that’s a part of the magic and mystery many of us find so fascinating about numbers stations.  The messages are (still) everywhere and broadcast publicly, yet, we have no clue of the meaning.

If you’ve never heard a numbers station, check out this audio of the numbers station, “The English Man” I recorded earlier this year:
