SUN CORONA HOLE 2016 PATCH

Thanks to particular optical characteristics of the machines we use to look at the sun, these solar gusts appear as holes in the corona. Solar flares and coronal ejections can knock out GPS service, disrupting navigation systems and weirdly popular augmented reality gaming trends. That's where the Pokémon Go business comes in. In extreme cases, they can trigger geomagnetic fluctuations that light up the auroras, mess with power grids and interrupt the functions of communication satellites. These high intensity streams boost the radiation environment surrounding our planet. The trouble happens when this solar wind rotates around and sends streams of high speed plasma in Earth's direction. The sun has been doing this for a long time. Instead, they shoot out past the corona and into the solar system. However, sometimes those magnetic field lines are not closed. That's what we 'see' when we squint real hard, optically speaking. So long as everything is trapped in a closed coronal loop, the superheated plasma shines brightly in the extreme ultraviolet wavelengths monitored by those SDO cameras.

The solar corona is a highly dynamic region created by arcs of magnetism that erupt from the sun's interior. To get a grip on what it really is, we need to know a bit more about the corona itself.

The images reveal a massive dark patch that looks like a hole in the sun. The video in question was recorded by NASA's Solar Dynamics Observatory, or SDO, and it shows the sun's corona - the superheated solar atmosphere that surrounds our species' favorite star. Ian O'Neill has the details in today's DNews dispatch. “We don’t know how the sun’s magnetic cycle works,” says Tim Horbury of Imperial College London.If you're susceptible to alarmist viral video posts, you may have noticed a strange bit of footage making the rounds in recent weeks. The trouble is that we can’t predict when and where these holes and ejections will happen. It is here that the sun’s magnetic field stretches out into the solar system, releasing gas from the sun’s atmosphere, the corona, that becomes the solar wind. These holes can span 50 times the diameter of Earth. Change your view to ultraviolet or X-rays, however, and a different picture emerges dark regions known as coronal holes come and go on timescales of days, weeks, months or years. Seen in visible light, the sun appears constant. The key to protecting ourselves is to understand the sun’s capricious magnetism. Since then, space weather has become a rising national priority in the UK and US. In 2008, the American National Academy of Sciences estimated that a Carrington event could cost the US economy alone $2 trillion. Transformers could be destroyed, bringing down power grids across nations. Satellites could burn out, and our communications and positioning systems with them. Today it would be a disaster, thanks to our reliance on electromagnetic technologies. Named after the British amateur astronomer Richard Carrington – who took observations of it – to most on the ground the Carrington event was little more than a spectacular light show. Auroral storms burst over two-thirds of the planet’s skies, compasses went haywire, and the telegraph system across the world malfunctioned as phantom currents surged through the wires. On 2 September 1859, a giant ejection of matter and magnetism erupted from the sun and struck Earth.
