Yellowknife aurora forecast 2019

The purple results from a mixture of blue and red emissions from nitrogen molecules.The bottom edge of the aurora is typically about 60 miles (100 kilometers) above the surface of the Earth. The chances of seeing the aurora at lower latitudes increase when the sunspot cycle is at a maximum, but chances at higher latitudes are not as dependent on the solar maximum because the auroral oval is normally present.For specific information on accommodations, tour companies, etc., we suggest People who live in Fairbanks, Alaska, are accustomed to spectacular views of the aurora borealis.

Yellowknife is the best place in the world to view the aurora borealis, also known as the Northern Lights. Sunspot activity, and hence auroral activity, tends to peak every 11 years. During years of minimum solar activity, auroral storms start north of Fairbanks and occur in the midnight hours.Although trees make good foreground in auroral photographs, too many of them can limit the full experience of the aurora. The skies at night are simply too bright as the sun climbs in the sky until the June 21 solstice and then descends. This allows good forecasts to be made on these look-ahead time scales, based on events and conditions observed on the sun.Just as Earth rotates on its axis making a complete rotation every 24 hours, the sun spins on an axis making a complete rotation in 27 days.

The top of the visible aurora peters out at about 120 to 200 miles (200 to 300 kilometers), but sometimes aurora can be seen as high as 350 miles (600 kilometers). The aurora is most often seen as a striking green, but it also occasionally shows off other colors, ranging from red to pink or blue to purple.

As the electrons from the solar wind penetrate into the upper atmosphere, the chance of colliding with an atom or molecule increases the deeper into the atmosphere they go.The two figures below show the locations with the most frequent occurrences of aurora borealis (left) and aurora australis (right) during the period of best viewing around the middle of the night.This level of auroral activity, index Kp=2, will occur often enough that you will probably see the aurora if you travel to these regions when the nights are dark and stay for three days to a week, assuming that the skies are clear. Yellowknife is the best place in the world to view the aurora borealis, also known as the Northern Lights. If the auroral activity level is higher than 2, you will still observe the stronger motions and color changes, etc., that are seen farther equatorward.The composition and density of the atmosphere and the altitude of the collisions determine the colors. This is known as the solar cycle and is measured by the number of sunspots visible on the sun. Note that during the spring, the skies of Iceland and Scandinavia are usually clear. This is a once-in-a-lifetime experience for the aurora watcher. The more sunspots, the more solar flare energy is being released into space (which means more aurora activity!). It may only be accomplished successfully during the most active overhead displays, on windless nights and away from any other noise sources such as barking dogs or traffic noise.The aurora is a luminous glow seen around the magnetic poles of the northern and southern hemispheres.

As the sun rotates, the solar phenomena and resulting areas of high-speed plasma are likely to reoccur every 27 days until the phenomena dissipate. Contacts The solar plasma is so hot that it breaks free of the sun's gravitational force and blows away from the surface in all directions. Major solar storms can occur any time; the aurora is usually most intense between 10 p.m. and 2 a.m. The chances of seeing the aurora at lower latitudes increase when the sunspot cycle is at a maximum, but chances at higher latitudes are not as dependent on the solar maximum because the auroral oval is normally present.The Kp number is a system of measuring aurora strength. Late summer to early autumn often also offers a good chance of seeing the lights. Data from these satellites provide about one to two hours' warning of an upcoming aurora.Streams of charged particles that produce the aurora come from the corona, the outermost layer of the sun's atmosphere. The Astronomy North aurora forecast is updated daily before noon Mountain Time. Your aurora-viewing experience depends on many factors, not all of which can be represented in the forecast. Places like Fairbanks, Alaska; Dawson City, Yukon; Yellowknife, NWT; Gillam, Manitoba; the southern tip of Greenland; Reykjavik, Iceland; Tromsø, Norway; and the northern coast of Siberia all offer a good chance to view the aurora overhead. Every eleven years or so it beats, and it beats hard.

The resulting gas of charged particles is called plasma, which is electrically conductive.
