Overview of Aurora
In early 2021, she released two compilation EPs in celebration of her song “Runaway” receiving over 100 million streams on Spotify: For the Humans Who Take Long Walks in the Forest and Music for the Fellow Witches Out There on 4 and 11 February, respectively.[36][37]

Earth’s magnetosphere is shaped by the impact of the solar wind on the Earth’s magnetic field.This forms an obstacle to the flow, diverting it, at an average distance of about 70,000 km (11 Earth radii or Re),[53] producing a bow shock 12,000 km to 15,000 km (1.9 to 2.4 Re) further upstream.The width of the magnetosphere abreast of Earth, is typically 190,000 km (30 Re), and on the night side a long “magnetotail” of stretched field lines extends to great distances (> 200 Re).The high latitude magnetosphere is filled with plasma as the solar wind passes the Earth.The flow of plasma into the magnetosphere increases with additional turbulence, density, and speed in the solar wind.This flow is favored by a southward component of the IMF, which can then directly connect to the high latitude geomagnetic field lines.[54] The flow pattern of magnetospheric plasma is mainly from the magnetotail toward the Earth, around the Earth and back into the solar wind through the magnetopause on the day-side.In addition to moving perpendicular to the Earth’s magnetic field, some magnetospheric plasma travels down along the Earth’s magnetic field lines, gains additional energy and loses it to the atmosphere in the auroral zones.The cusps of the magnetosphere, separating geomagnetic field lines that close through the Earth from those that close remotely allow a small amount of solar wind to directly reach the top of the atmosphere, producing an auroral glow.On 26 February 2008, THEMIS probes were able to determine, for the first time, the triggering event for the onset of magnetospheric substorms.[55] Two of the five probes, positioned approximately one third the distance to the moon, measured events suggesting a magnetic reconnection event 96 seconds prior to auroral intensification.[56]
Network
The discovery of a 1770 Japanese diary in 2017 depicting auroras above the ancient Japanese capital of Kyoto suggested that the storm may have been 7% larger than the Carrington event, which affected telegraph networks.[67][68]

One early theory proposed for the acceleration of auroral electrons is based on an assumed static, or quasi-static, electric field creating a uni-directional potential drop.[59] No mention is provided of either the necessary space-charge or equipotential distribution, and these remain to be specified for the notion of acceleration by double layers to be credible.Fundamentally, Poisson’s equation indicates that there can be no configuration of charge resulting in a net potential drop.Inexplicably though, some authors[60][61] still invoke quasi-static parallel electric fields as net accelerators of auroral electrons, citing interpretations of transient observations of fields and particles as supporting this theory as firm fact.In another example,[62] there is little justification given for saying ‘FAST observations demonstrate detailed quantitative agreement between the measured electric potentials and the ion beam energies…., leaving no doubt that parallel potential drops are a dominant source of auroral particle acceleration’.

What makes this happen?
Even though auroras are best seen at night, they are actually caused by the Sun.
How do I get tested for COVID-19?
We’re offering COVID-19 tests at our urgent care locations.Get your test via walk-in or schedule an appointment in LiveWell or by calling 866-443-2584.Stay up to date about COVID-19 in our Resource Center.
Do other planets get auroras?
They sure do! Auroras are not just something that happen on Earth.If a planet has an atmosphere and magnetic field, they probably have auroras.We’ve seen amazing auroras on Jupiter and Saturn.

COVID-19 Antigen Rapid Test: What is it and what does it do?
The COVID-19 Antigen Rapid test is an immunoassay that is used to detect the rapidly detect (in less than 15 minutes) the presence of SARS-CoV-2 viral antigens.
What Causes The Northern Lights?
Short answer? The sun.
What are the Northern Lights (Aurora Borealis)?
The northern lights surprise stargazers by appearing in many forms—from patches or
scattered clouds, to streamers, arcs, rippling or dancing curtains.The lights move
and change shape and color.Scientists attribute their vibrant colors to excited gases emitted in Earth’s atmosphere; oxygen gives off the green color of the aurora.
What causes the colors?
The colors most often associated with the aurora borealis are pink, green, yellow, blue, violet, and occasionally orange and white.Typically, when the particles collide with oxygen, yellow and green are produced.Interactions with nitrogen produce red, violet, and occasionally blue colors.
What Is an Aurora?
If you’re ever near the North or South Pole, you may be in for a very special treat.Frequently there are beautiful light shows in the sky.These lights are called auroras.If you’re near the North Pole, it is called an aurora borealis or northern lights.If you’re near the South Pole, it is called an aurora australis or the southern lights.
