1 天前 · When and where can you see the northern and southern lights also known as the aurora? This page provides a prediction of the aurora’s visibility tonight and tomorrow night in the charts below. The animations further down show what the aurora’s been up to over the last 24 hours and estimates what the next 30 minutes will be like.

The aurora is an indicator of the current geomagnetic storm conditions and provides situational awareness for a number of technologies. The aurora directly impacts HF radio communication and GPS/GNSS satellite navigation.

This is a prediction of the intensity and location of the aurora borealis tonight and tomorrow night over North America. It also shows a 'viewline' that represents the southern-most locations from which you may see the aurora on the northern horizon.

Real-time aurora forecast with clear sky detection. Discover the best locations to see the northern lights tonight with our interactive map. To accurately predict when and where you can see the northern lights, we track three 3 essential measurements: KP index 1, HPI 2, and Bz 3.

2024年11月18日 · Live updates on aurora activity and viewing chances with tips on the best spots for peak northern lights visibility.

2024年11月21日 · When that wind slams into Earth's ionosphere, or upper atmosphere, the aurora is born. In the Northern Hemisphere, the phenomenon is called the northern lights (aurora borealis), while in the...

2025年2月4日 · Auroras are vibrant light displays created when energetic particles from the Sun interact with Earth’s magnetic field and atmosphere. These events, also seen on other planets like Saturn and Jupiter, result in a range of colors depending on altitude and the atmospheric gases involved. Scientists study auroras using tools like rockets, balloons, and ground-based …

2025年1月21日 · An aurora is a glowing light show in the Earth's upper atmosphere, occurring at altitudes between about 85 and 600 km. These stunning displays begin when the sun's charged particles reach the Earth's magnetic field, or magnetosphere. The particles travel on the streaming solar wind or as bursts during coronal mass ejections, which are often ...

4 天之前 · The best chances for aurora sightings will be at high latitudes, including Canada, Alaska and parts of the northern U.S. If geomagnetic activity is strong enough, skywatchers in northern Michigan ...

Aurora is Colorado's third largest city with a diverse population of more than 398,000. The "Gateway to the Rockies" is a bioscience, transportation and aerospace hub with award-winning parks, open space and cultural amenities.

2024年5月10日 · What is an aurora, and why do they come in different shapes and colors? An aurora is one of nature’s most spectacular sights, a dazzling glow in the upper atmosphere driven by space weather....

2023年10月19日 · An aurora is a natural light display that shimmers in the sky. Blue, red, yellow, green, and orange lights shift gently and change shape like softly blowing curtains. Auroras are only visible at night, and usually only appear in lower polar regions.

The aurora is a luminous glow frequently seen around the geomagnetic poles of the northern (aurora borealis) and southern (aurora australis) hemispheres. The light is caused by collisions between electrically charged particles streaming from outer space that enter Earth’s atmosphere and collide with molecules and atoms of gas (primarily ...

2 天之前 · "The aurora may become visible along the horizon of northern tier and far north upper Midwest states," the agency said on Friday. Michigan and Maine may also see an aurora, NOAA said in an advisory .

What is the Aurora? Aurora is the name given to the glow or light produced when electrons from space flow down Earth’s magnetic field and collide with atoms and molecules of the upper atmosphere in a ring or oval centered on the magnetic pole of Earth.

Named for the Roman goddess of dawn, the aurora is a mysterious and unpredictable display of light in the night sky. The aurora borealis and aurora australis – often called the northern lights and southern lights – are common occurrences at high northern and southern latitudes, less frequent at mid-latitudes, and seldom seen near the equator.

Aurora serves the homeless and near homeless in Evansville, IN, and provides permanent, long-term housing solutions for those experiencing homelessness. We believe that our community and its families will be stronger when everyone has a safe, decent, and sustainable place to call home.

2023年5月17日 · The aurora borealis lights up the night sky behind Iceland's iconic Kirkjufell volcano. Auroras are caused when charged particles from the sun collide with gases in Earth's atmosphere.

2017年3月30日 · A geomagnetic storm lies behind every inspiring aurora in our skies. The mystery behind these shimmering curtains of neon-like light isn’t a mystery to scientists who study space weather. Rather than the calm before the storm, aurora is …

2 天之前 · Aurora, luminous phenomenon of Earth’s upper atmosphere that occurs primarily in high latitudes of both hemispheres; in the Northern Hemisphere auroras are called aurora borealis, aurora polaris, or northern lights, and in the Southern Hemisphere they are called aurora australis or southern lights.

When space weather activity increases and more frequent and larger storms and substorms occur, the aurora extends equatorward. During large events, the aurora can be observed as far south as the US, Europe, and Asia. During very large events, the aurora can be observed even farther from the poles.

5 天之前 · Argonne National Laboratory has fully opened its Aurora exascale supercomputer to researchers across the world, heralding a new era of computing-driven discoveries. Aurora is one of the world’s first exascale supercomputers, capable of performing at least a quintillion (or a billion billion) calculations per second.
