Northern Lights Viewing in Alaska | Canada
Q: How about Aurora Viewing
A: Ideal viewing time is approximately from 7-days prior to the New Moon and until 7-days after the New Moon. While some people may be concerned that a full moon is a problem, only weak aurora may be obstructed by the light of the moon, but in Alaska the aurora is generally strong enough that aurora viewing is still possible - even during a moonlit night. As far as aurora photography goes, the aurora above a moonlit landscape actually tends to have a pleasing effect. On the whole, when participating in an aurora tour, one doesn’t need to be worried about the moon. The moon does not influence the aurora activity, the sky is just darker. You can therefore travel any time of the month from September to April.
Aurora Viewing | Prime Viewing Dates
Q: When is the best time of the year to see the Aurora
A: In northern regions such as Alaska, the Yukon Territory, Northern British Columbia and the Northwest Territories - the Northern Lights (Aurora Borealis) are seen from late August to mid April. Furthermore, during the autumn and spring, the weather is rather unstable and has a lower percentage of clear skies. Therefore, we have determined the best viewing seasons to be from mid-August to the end of September and from mid-November to mid-April. In This time of the year offers the best trade off between mild weather and dark skies. During the summer months, night skies are not dark enough to view the Aurora Borealis and in midwinter temperatures in the – 40 degree range make outdoor aurora viewing somewhat unpleasant. In other locations farther from the average aurora oval, the main consideration is the level of geomagnetic activity, which varies rather unpredictably through the year.
Q: When is the best time of the day
A: Within the most active regions of Alaska and prime viewing areas the Aurora oval typically becomes visible around local midnight. Note: this is an astronomical midnight - which may be an hour or two different from the civil or the “ wall clock “ midnight due to daylight savings time and/or peculiarities in your time zone. Spectacular Aurora displays due to geomagnetic disturbance may be seen at any time when the sky is dark, but they are relatively unpredictable. Under average conditions, observations around local midnight are most likely to yield results.
Q: What are the Temperatures in the Northern Regions
A: The average daily temperatures in February/March are approximately +20/-30 - equivalent to –8/-33 degrees Celsius.
Q: How to observe the Aurora
A: If you follow our recommendations you should be able to enjoy some pleasant Aurora viewing.
- A: Ensure - that you be there when the action begins. Because more often than not, the show picks up very quickly and also fades out as quickly as it started! Most of the auroras are out only about 2 to max 10 minutes at ones.
- A: Be Patient - this is maybe the most important thing in aurora viewing. If the show starts, it's always worth. Seeing a full-blown aurora show is just an indescribable experience.
- A: Experience - this is maybe the second most important (human) factor in aurora viewing. If you are first patient and then successful in seeing auroras, the direct consequence is that you will gain of course - experience. After a while you will begin to recognize what the aurora is doing, in which phase it is and so on. And the most important thing - You will learn how a weak aurora looks like!!! Because, even that we are hoping to see a bright "eruption phase " aurora, the aurora isn't all the time bright. So the experience will help you to see and determine if there is a weak aurora, which could get brighter in the future! I
- A: Light Conditions - the primary reason for not seeing an aurora are any city light obstruction or a bright twilight. Our destinations are far away from a city or other light obstruction and therefore should guarantee the best viewing conditions possible.
- A: Weather - don't think overcast weather prevent you from Aurora viewing. Although often clouds do ruin everything, but at times...you can also get lucky breaks! Another example, during a major aurora storm in 2001 the forecasts and satellite pictures showed that it should be overcast, but it was not. We could see the stars and the aurora through the thin clouds! So, give it a try anyway...it could be worth it!
Q: What causes the Aurora
A: Energetic charged particles from the magnetosphere. These particles are electrons and protons that are energized in the near geo-space environment. This energization process draws its energy from the interaction of the Earth's magnetosphere with the solar wind. The magnetosphere is a volume of space that surrounds the Earth. We have this magnetosphere because of Earth's internal magnetic field. This field extends to space until it is balanced by the solar wind.
Q: What is the altitude of the Aurora Borealis
A: The bottom edge is typically at 100 km (about 60 miles) altitude. The aurora extends over a very large altitude range. The altitude where the emission comes from depends on the energy of the energetic electrons that make the aurora. The more energy the bigger the punch, and the deeper the electron get into the atmosphere. Very intense aurora from high-energy electrons can be as low as 80 km (50 miles). The top of the visible aurora peters out at about 2-300 km (120-200 miles), sometimes high altitude aurora can be seen as high as 600 km (350 miles). This is about the altitude at which the space shuttle usually flies.
Sun | Solar Wind | Magnetosphere
The solar wind is the outermost atmosphere of our sun. The sun is so hot that it boils off its outer layers, and the result is a constant outward expanding very thin gas. This solar wind consists not of atoms and molecules but of protons and electrons (this is called a plasma). Embedded in this solar wind is the magnetic field of the sun. The density is so low that we may well call it a vacuum. However tenuous it is, when this solar wind encounters a planet, it has to flow around it. When this planet has a magnetic field, the solar wind sees this magnetic field as an obstacle, as protons and electrons cannot move freely across a magnetic field. These charged particles are constrained to move almost always only along the magnetic field. Likewise, when they are forced to move in a specific direction, a magnetic field will move with them or will be bent into the direction of the flow. Whether the magnetic field forces the plasma motion or whether the plasma motion bends the magnetic field depends on the strength of the field and the force of the motion. When the solar wind encounters Earth's magnetic field, it will thus bend the field unless the field gets too strong. The strength of the magnetic field falls off with distance from Earth. The distance at which the solar wind and the magnetic field of the Earth balance each other is about 60,000 km away, or 1/10 of the distance to the moon. The inside of this volume that is bounded by the solar wind is called the magnetosphere. At the interface of the solar wind and the magnetosphere, energy can be transferred into the magnetosphere by a number of processes. Most effective is a process called reconnection. When the magnetic field in the solar wind and the magnetic field of the magnetosphere are anti-parallel, the fields can melt together, and the solar wind can drag the magnetospheres field and plasma along. This is very efficient in energizing magnetospheres plasma. Eventually, the magnetosphere responds by dumping electrons and protons into the high latitude upper atmosphere where the energy of the plasma can be dissipated. This then results in aurora. Here is an animation (1.6Mb) that illustrates this process.

Q: How do I take the best pictures
A: For the first -time or for seasoned aurora photographer, a 35 mm camera on a tripod equipped with a cable release is a must. Use a wide-angle 24 mm to 50 mm lens and set it to an f-stop which is the fastest – or one slower to avoid distortion of bright star images – usually f/1.4 – f/2.8.
- Exposures of 5 to 15 seconds work well unless the aurora is faint or mostly stationary, in which case the exposure time should be doubled. People tend to overexpose their photos, causing the aurora to look washed out. If the aurora is bright, moonlight and city lights should not interfere and can offer an interesting foreground. Never use filters because they could cause internal reflections. If it is very dark, a silhouette of a tree of lit cabin will certainly add to the scene. Video cameras are normally not sensitive enough to successfully record the aurora.
- Because aurora occurs under clear skies, photographers will often be shooting in temperatures well below zero. Since cold saps camera batteries, it is advisable to use an older camera with mechanical shutter instead of one that is fully automatic. Cold makes plastic brittle, so the cable release should be wired mesh vice plastic. At minus 40 Fahrenheit, all cameras will freeze in less than 10 minutes; before taking it inside to warm, place it in a zip-lock plastic bag to reduce condensation.
- Tape the lens to infinity so that it doesn’t slip and cause your images to be out of focus. Don’t try for a 37th exposure; it might break the film, and it is best to overexpose your first frame on the roll so that the film processor knows where to start cutting your negatives. Wind your finished roll of film slowly so that it doesn’t shatter or cause static buildup – this may appear as scratch. While Kodak film processing mailers are generally reliable, it may be worth the extra cost to have the film processed through a custom photo lab. Going the custom lab route will save the film from being lost in the mail or scratched in an automated process.
- Slower speed film (print or slide) has better gain resolution; making for a sharper image when enlarged. Thus it may be too slow to record the fine detail structure of the aurora.
- Medium-speed color film (200 /400 ASA) works as well. Purists insist on slide film. You can try a faster film, but keep in mind that graininess and color quality tend to decrease with increasing film speed. We recommend using 400-speed film is a good compromise between detail and quality of the image.
- Different films will emphasize different colors of the aurora, so experimentation is advisable. Bracketing your exposures (05 seconds, 10 seconds and 15 seconds) will give you the characteristics of the film. Even in a roll of 36 exposures, there are only a few shots that are acceptable to me.
Q: Can I videotape the Aurora
A: Videotaping the aurora generally takes highly specialized video equipment. Generally – camcorders are not sensitive enough to see the aurora, though a few will record a faint, smoky image given a sufficiently bright aurora. Your best bet for video showing the color and motion of the aurora is to purchase a professionally – recorded tape such as one distributed form the Geophysical Institute in Fairbanks. Thus, some home video cameras are capable of picking up bright auroras. In particular, a camera rated at for example: less than one-lux sensitivity has captured – faintly and colorlessly a bright auroral arc. Many cameras which have special features such as digital zoom and / or vibration compensation are much less sensitive and will not show the aurora. The most annoying problem with home video cameras in low-light situations is their inability to focus. If your camera has a focus-lock button, you may be able to focus on a distant, brightly-lit object, and lock the focus then see if you can pick up the moon or perhaps catch a hint of an extremely bright aurora. Just don’t expect much, because home video cameras aren’t designed to do low-light recording.
Q: Do you have any Aurora Photography Tips
A: When you do your research for shooting the aurora, you’ll find pluses and minuses for going when a full moon is present. On the minus side is if the lights that night are somewhat faint, the brightness of the moon’s reflection of the sun can fade them out. On the other hand, a full moon can be used to illuminate objects in the foreground. Many aurora shots include buildings with lights on inside to provide an interesting foreground subject. Depending on your shooting location, this feature might not be available. However, a full moon will help light up anything you have in front of you, no matter where you are. Because shots are done for at least six to eight seconds and up to fifteen seconds or more (depending on your shutter and ISO settings), the full moon will do a great job of making what would otherwise be a silhouette into a well-lit subject. Conversely, if you choose to go when there isn’t a full moon, a strong flash can be helpful in popping light onto a foreground subject.
