The Sun lets out a brief flare | Bad Astronomy

Around 02:00 UTC last night (July 30, 2011), a sunspot named Active Region 1261 erupted with a short solar flare, which was caught by NASA’s Solar Dynamics Observatory. Using Helioviewer I created a short video of the event:

[Make sure to set the resolution to at least 720p!]

Those bright regions are actually sunspots, which are dark at wavelengths our eyes can see, but are quite bright in the ultraviolet. Solar flares occur when the Sun’s magnetic field lines get twisted up. They store a lot of energy, and when tangled they can suddenly snap, releasing that energy. Astronomers classify flares by the energy released in X-rays, from Classes A,B, and C (weak) to M (moderate) to X (yikes!). This one was an M9, which is on the low end of the M class. Powerful, but probably not enough to affect us here 150 million kilometers away. If anything, there may be a stronger than normal aurora in a day or two.

The Sun’s activity waxes and wanes on a roughly 11 year cycle, and we’re on the upswing of Cycle 24. There was an unusually long quiet period after Cycle 23 and ...

New Sharia Law Zones in London explained

No Alcohol; No Gambling; No Music; No Porn; No Smoking; No Drugs

From Eric Dondero:

London and surrounding suburbs are being taken over by Islamic Jihadists.

"It's no longer your land. It's Allah's land... Holy shit, what's going on here... Coming to a neighborhood near you."

There has been little if any reporting by major media sources on the new Sharia Zones.

Islamists set up Sharia Law Zones in London: Where’s the outcry from the so-called libertarian community?

Sharia-compliant posters now dot London and surrounding suburbs

by Eric Dondero

The London Daily Mail reports July 28, "'No porn or prostitution': Islamic extremists set up Sharia law controlled zones in British cities"

Islamic extremists have launched a poster campaign across the UK proclaiming areas where Sharia law enforcement zones have been set up.

Communities have been bombarded with the posters, which read: ‘You are entering a Sharia-controlled zone – Islamic rules enforced.’

The bright yellow messages daubed on bus stops and street lamps have already been seen across certain boroughs in London and order that in the ‘zone’ there should be ‘no gambling’, ‘no music or concerts’, ‘no porn or prostitution’, ‘no drugs or smoking’ and ‘no alcohol’.

Islamist beliefs extreme polar opposite of Libertarianism

Libertarians are explicitly in support of the legalized gambling, free speech including explicit lyrics in music, adult pornography, prostitution, no smoking bans, and legalization of drugs.

A check of top libertarian websites show no other libertarian media, outside of this website and one other, covering or even mentioning this story.

There is nothing at the Libertarian Party website LP.org. None of the Ron Paul websites such as Daily Paul and Campaign For Liberty are covering the story. LewRockwell.com is silent. Cato.org is similarly mum. The most popular culturally libertarian site Reason.com, which regularly features legalize porno, free speech, prostitution, and drug issues has nothing on the London story. A check of smaller libertarian sites, such as NolanChart.org, The Humble Libertarian, or The Agitator (another one that emphasizes the civil liberties side), haven't said a word.

LINOs - Libertarians In Name Only?

Selective coverage perhaps? No doubt, if this had been a Christian Conservative group putting up such stickers in say Memphis, Denver or San Francisco, the outcry from such websites would be deafening.

Reason alone would be covering the story on the front page of their magazine, and as the header for their website. Dave Boaz, openly gay VP at Cato, would be screaming bloody murder at the "homophobic and sexually intolerant" Christians. Wes Benedict, Director at Libertarian Party HQ, would have issued a press release condemning the "Christian bigots," within hours of the story breaking.

But as it is, criticisms of Islamism and opposition to the Islamic agenda on repealing individual liberties, is not politically correct for these increasingly LINO (Libertarian In Name Only) sites and groups.

Of Note - Gates of Vienna, whose editor-in-chief and co-editor are die-in-the-wool self-described "libertarians," is one website that featured the London story. Oddly enough, GofV is not considered to be a "real libertarian" website by the others listed.
