![]() ![]() Generally, the further north you are, the better the likelihood of seeing the Northern Lights.Īccording to the British Geological Survey, you might see the aurora in the far north of Scotland every few months, but less often if you travel further south. Oxygen gives off green and red light, while nitrogen glows blue and purple. There, the particles interact with gases in our atmosphere, resulting in beautiful displays of light in the sky, known as auroras. When a CME hurtles towards Earth, some of the energy and small particles can travel down the magnetic field lines at the north and south poles into our planet's atmosphere. The green ovals turn red when the aurora is forecasted to be more intense, which is when people further away from the poles have the better chance of seeing them. ![]() In a new NOAA animation, the brightness and location of the aurora is shown as a green oval centered on Earth's magnetic pole. 'There is a slight chance that the auroral oval could move further north to allow views from the south of mainland Australia and South Island of New Zealand given clear viewing conditions of the southern horizon.' 'In the most likely scenario aurora would become visible to the far south of New Zealand and Tasmania,' the Met Office said. In the southern hemisphere, there will be 'significant enhancements' to the auroral oval, but not until late Wednesday or early Thursday. In the Earth's north, the Northern Lights are officially known as the aurora borealis, while in the south, the event is called aurora australis. 'There is a slight chance that the auroral oval could move further south to allow views from North Wales and the Midlands given clear views of the northern horizon.' 'In the most likely scenario aurora would become visible where skies are clear to Scotland as well as the north of England and Northern Ireland,' the Met Office said in a statement. It suggests the aurora will be visible on Wednesday and Thursday nights too, in case anyone misses the opportunity tonight. The data for this new mosaic image was collected as NASA's sun-touching spacecraft, the Parker Solar Probe, made its 12th close pass of the star, racing through the outer limits of its corona and coming closer to the sun than any other craft ever had done before.A Met Office animation shows the auroral oval – the ring-like range of auroral activity that determines the range of the Northern Lights. This could eventually allow solar physicists to see the frequency of nanoflares, how they release energy, and thus whether they are responsible for coronal heating. Individual nanoflares are too faint to spot amongst the sun's light output, but NuSTAR can spot radiation from high-temperature material created by a lot of nanoflares happening in the same location at the same time. Regular flares don't happen frequently enough to heat the corona, but nanoflares may happen more regularly, perhaps often enough to cause this excess heating. These are smaller than regular solar flares but like their larger cousins, also produce material hotter than the average temperature of the corona. The source of this unexpected heating may be nanoflares, small bursts of heat, and light in the sun's atmosphere. ![]() NASA says that because heat from the sun passes out from its core, this is as surprising as the air around a fire being 100 times hotter than the flames of the fire itself. Common theories of star composition suggest that deeper layers should be hotter, and this is true everywhere throughout the sun except when passing from the upper atmosphere, the corona, which can reach temperatures of up to 3.6 million degrees Fahrenheit ( 2 million degrees Celsius), to the photosphere below, which, at about 6,200 degrees F (3,700 degrees C) is up to 500 times colder. ![]()
