Also, a quick tip: To predict the aurora display strength, refer to the Kp-index. Note that the higher the Kp-index, the stronger the display. (There are other factors involved in predicting the northern lights, but the Kp-index is the easiest and most convenient.)
Aurora Borealis torrent
Solar flares, or intense radiation bursts from the sun, release a torrent of particles and electromagnetic energy toward Earth, flooding the atmosphere with lights that radiate around the North and South Poles. Ensuing light shows in the north are called aurora borealis, or "northern lights," and lights in the south are aurora australis. [Earth from Above: 101 Stunning Images from Orbit]
The auroras at opposite ends of the Earth are not mirror images of each other. Intense sun spots are often seen at dawn in the Northern Hemisphere in summer and at dusk in the Southern Hemisphere in winter, according to research reported in the journal Nature (opens in new tab).
We can thank a sunspot for the brilliant aurora australis in the NASA image. Sunspot AR 12371 sizzled with flares, radio bursts and solar storms as it glided across the Earth-facing side of the sun. Between June 20 and 21, the sunspot launched a coronal mass ejection, a giant eruption of solar wind made up of energetic particles and energy from the sun, which resulted in a severe geomagnetic storm from June 22 to 23. Another flare erupted June 23 and most likely caused the light display in the NASA image.
Auroras are typically a relatively strong source of light, but are ephemeral and only rarely spotted at lower latitudes. The northern and southern lights can conjure thoughts of dreamlike pillars of dancing light that fill the night sky. The spectacle is called aurora for the Roman goddess of dawn, but unlike its namesake, does not follow a predictable schedule.
Astronaut Scott Kelly, who is currently on a one-year mission aboard the International Space Station, posted an aurora photograph on Twitter on June 23 that shows an upside-down Earth with a halo of luminous soft, blue light that transitions to an outer glow of cherry red.

The world's newest and biggest space telescope is showing Jupiter as never before, auroras and all. Scientists released the shots on Monday of the solar system's biggest planet. The James Webb Space Telescope took the photos in July, capturing unprecedented views of Jupiter's northern and southern lights, and swirling polar haze.
This Achilles Heel of sorts sit right at the poles, where the looping field lines part, and plasma can sneak through into the atmosphere. When these high-speed, energetic particles slam into the molecules floating around above the planet, they often excite them enough to release a dazzling shower of iridescent, sinuous light. We call them auroras, and they usually appear near both the North and South poles.
For when I would account to myself for the birth of that passion, which afterwards ruled my destiny, I find it arise, like a mountain river, from ignoble and almost forgotten sources; but swelling as it proceeded, it became the torrent which, in its course, has swept away all my hopes and joys.
As a river roars down its steep course in a torrential flood, it pulls everything with it. Tons of soil and sand are sucked up and held in a roiling suspension. But when the river slows, meandering through flatter lands, the water drops its heavy burden. The soil and sand settle out to form silt on the river bed.
I have endured the thunder of little feet running around swanky restaurants and wailing torrents of nonsense in otherwise serene art galleries. I have sat through a visit to the cinema to which somebody brought their newborn baby and I have been used as a climbing frame and punchbag on public transport. The only safe place is at my desk. It's a bold statement, but I am sick of my leisure time being spoiled by parents who don't restrain their children because they assume/expect/demand that I find them as entertaining as they do. Empathy goes out the window when you have a child, because all other pursuits (such as reading, eating out, watching a film, chatting or simply minding your own business) are deemed hollow and selfish; we are just teenagers revelling in the trappings of modern misanthropy. 2ff7e9595c
