Chasing the Northern Lights: A Guide to Viewing the Aurora Borealis

Introduction to the Aurora Borealis

What is the Aurora Borealis?

The Aurora Borealis, also known as the Northern Lights, is a breathtaking natural phenomenon that illuminates the night sky with mesmerising displays of colourful light. This awe-inspiring spectacle is visible in the high-latitude regions near the Arctic, such as Iceland, Norway, Finland, Scotland, and Northern Canada. The Aurora Borealis is caused by the interaction between charged particles from the sun and the Earth's magnetic field, resulting in a celestial dance of green, pink, red, and purple hues that captivate observers from around the world.

The Mythology and History of the Aurora Borealis

Throughout history, the Aurora Borealis has been the subject of countless myths, legends, and folklore. In Norse mythology, the Northern Lights were believed to be the reflections of the shields and armour of the Valkyries, the female warriors who guided fallen soldiers to the afterlife. The Sami people of northern Scandinavia believed that the lights were the energies of the souls of the departed. In some Inuit cultures, the Aurora Borealis was seen as a way for the spirits to communicate with the living. These ancient stories and beliefs demonstrate the enduring fascination and cultural significance of the Northern Lights throughout human history.

When and Where to See the Aurora Borealis

The best time to see the Aurora Borealis is typically from late September to early April, when the nights are longer and darker in the Northern Hemisphere. The Aurora Borealis is most frequently observed within the "auroral zone," a ring-shaped area around the Earth's magnetic poles. Iceland, Norway, Finland, and Northern Canada are among the best places to watch the Aurora Borealis, as they are located within this zone and offer clear, dark skies away from light pollution. To increase your chances of witnessing the Northern Lights, it is essential to check the Aurora Borealis forecast, monitor the local weather conditions, and be prepared to stay up late or wake up early to catch the display.

The Science Behind the Aurora Borealis

The Sun's Role in Creating the Aurora Borealis

The Aurora Borealis is ultimately caused by the activity of the sun. The sun constantly emits a stream of charged particles, known as the solar wind, which travels through space at high speeds. When these particles reach the Earth's magnetic field, they interact with the atoms and molecules in the Earth's upper atmosphere, causing them to become excited and release energy in the form of light. The type of solar activity, such as solar storms and coronal mass ejections, can greatly influence the intensity and frequency of Aurora Borealis displays.

The Earth's Magnetic Field and the Aurora Borealis

The Earth's magnetic field plays a crucial role in the formation of the Aurora Borealis. The magnetic field acts as a shield, protecting the planet from the majority of the charged particles emitted by the sun. However, some particles manage to enter the Earth's atmosphere near the magnetic poles, where the field is weaker. As these particles collide with atoms and molecules in the upper atmosphere, they transfer energy and cause the atoms to become excited. When the excited atoms return to their normal state, they release energy in the form of light, creating the magnificent displays of the Northern Lights.

The Colours of the Aurora Borealis

The colours of the Aurora Borealis are determined by the types of atoms and molecules involved in the collisions, as well as the altitude at which these collisions occur. The most common colour of the Northern Lights is green, which is produced by oxygen atoms at lower altitudes (around 60-150 miles above the Earth's surface). Red auroras are created by oxygen atoms at higher altitudes (up to 200 miles) and are less frequently observed. Blue and purple colours are produced by nitrogen molecules and are typically visible at the edges of the aurora displays. The colour diversity of the Aurora Borealis adds to its captivating beauty and mystique.

Studying and Forecasting the Aurora Borealis

Scientists use a variety of methods and instruments to study and predict the occurrence of the Aurora Borealis. Space weather satellites, such as NASA's Advanced Composition Explorer (ACE) and the joint European Space Agency and NASA Solar and Heliospheric Observatory (SOHO), monitor solar activity and provide valuable data on the speed, density, and direction of the solar wind. Ground-based observatories and radar systems, like the Super Dual Auroral Radar Network (SuperDARN), help researchers track the interactions between the solar wind and the Earth's magnetic field. This data is used to create Aurora Borealis forecasts and Aurora Borealis alerts, which help scientists, photographers, and enthusiasts plan their expeditions to witness the Northern Lights. Machine learning algorithms and artificial intelligence are also being developed to improve the accuracy of Aurora Borealis forecasts and further our understanding of this captivating phenomenon.

The Science of Forecasting the Aurora Borealis

The Role of Solar Activity in Aurora Borealis Forecasting

Forecasting the Aurora Borealis relies heavily on understanding and monitoring solar activity. The sun undergoes an 11-year cycle, during which the number of sunspots, solar storms, and coronal mass ejections (CMEs) fluctuates. These events release charged particles into space, which travel towards Earth and interact with its magnetic field, causing the Aurora Borealis.


Scientists use various instruments, such as the Solar Dynamics Observatory (SDO) and the Solar and Heliospheric Observatory (SOHO), to monitor the sun's activity and detect potential solar storms or CMEs that may trigger Aurora Borealis displays. By analysing this data, researchers can provide Aurora Borealis forecasts and alert the public to the likelihood of seeing the Northern Lights.

Monitoring Earth's Magnetic Field for Aurora Borealis Forecasting

In addition to solar activity, the Earth's magnetic field plays a crucial role in the formation and visibility of the Aurora Borealis. Scientists use a network of ground-based magnetometers to measure fluctuations in the Earth's magnetic field, which can indicate the presence of charged particles entering the atmosphere.


The Kp-index, a scale ranging from 0 to 9, is used to quantify the disturbance in the Earth's magnetic field and predict the likelihood of Aurora Borealis sightings. Higher Kp values indicate a greater probability of visible Northern Lights, with values of 5 or more considered to be good indicators of significant Aurora Borealis activity.

Aurora Borealis Forecast Models and Tools

Scientists have developed various models and tools to help predict the occurrence and intensity of the Aurora Borealis. The OVATION Prime model, developed by the National Oceanic and Atmospheric Administration (NOAA), uses real-time solar wind data to create short-term forecasts of Aurora Borealis activity.


Websites like and services like the Aurora Borealis Forecast from the University of Alaska Fairbanks provide regularly updated information on solar activity, geomagnetic disturbances, and the probability of seeing the Northern Lights in different locations.


Mobile apps, such as My Aurora Borealis Forecast and Aurora Borealis Alerts, offer personalised Northern Lights predictions based on the user's location and real-time solar and geomagnetic data.

Challenges and Limitations in Aurora Borealis Forecasting

Despite advances in technology and understanding of the factors that influence the Aurora Borealis, forecasting the Northern Lights remains an inexact science. The complex interactions between the sun, the Earth's magnetic field, and the atmosphere make it challenging to predict the timing, location, and intensity of Aurora Borealis displays with high accuracy.


Short-term forecasts, typically up to a few days in advance, are more reliable than long-term predictions. However, even short-term forecasts can be affected by sudden changes in solar activity or unforeseen geomagnetic disturbances.


Additionally, local weather conditions, such as cloud cover or precipitation, can significantly impact the visibility of the Aurora Borealis, even when the forecast indicates a high probability of activity.


Despite these challenges, Aurora Borealis forecasting continues to improve as researchers develop more sophisticated models and instruments for monitoring solar activity and geomagnetic disturbances. As our understanding of the complex processes behind the Northern Lights grows, so too will our ability to predict and witness this awe-inspiring natural phenomenon.

The Impact of Solar Storms on the Aurora Borealis

How Solar Storms Affect the Aurora Borealis

Solar storms, such as solar flares and coronal mass ejections (CMEs), have a significant impact on the Aurora Borealis. These events release enormous amounts of charged particles into space, which travel towards Earth at high speeds. When these particles interact with Earth's magnetic field, they can cause geomagnetic disturbances and intensify the Northern Lights.


During powerful solar storms, the Aurora Borealis can become more intense and visible at lower latitudes than usual. In some cases, the Northern Lights may be seen as far south as the United States or even central Europe, a rare and stunning sight for those living outside the typical auroral zone.


However, the effects of solar storms on the Aurora Borealis can be unpredictable, as the intensity and duration of the resulting geomagnetic disturbances depend on factors such as the speed, density, and magnetic field orientation of the incoming solar particles.

The Impact of Solar Storms on Technology and Infrastructure

While solar storms can create breathtaking displays of the Aurora Borealis, they can also have detrimental effects on technology and infrastructure. The charged particles and electromagnetic radiation released during solar flares and CMEs can interfere with satellite communications, GPS navigation, and power grids.


During severe solar storms, satellites may experience malfunctions or even permanent damage due to the increased radiation exposure. This can disrupt global communication networks, weather forecasting, and military operations that rely on satellite technology.


Solar storms can also induce geomagnetically induced currents (GICs) in power lines, transformers, and pipelines, potentially causing widespread power outages and damage to electrical infrastructure. In March 1989, a powerful solar storm caused a geomagnetic disturbance that triggered the collapse of the Hydro-Québec power grid in Canada, leaving millions of people without electricity for hours.

Monitoring and Mitigating the Effects of Solar Storms

To minimise the potential impacts of solar storms on technology and infrastructure, scientists and government agencies continuously monitor solar activity and space weather conditions. Organisations such as NASA, NOAA, and the European Space Agency (ESA) use a network of ground-based and space-based observatories to detect and track solar storms and provide timely warnings to industries and the public.


Satellite operators and power grid managers use this information to implement protective measures, such as adjusting satellite orbits, disconnecting vulnerable equipment, or redistributing power loads to minimise the risk of damage or disruption.


Research into improving the resilience of technology and infrastructure to the effects of solar storms is ongoing, with the development of more robust satellite designs, better shielding for electrical systems, and advanced materials that can withstand high levels of radiation and electromagnetic interference.

The Role of Solar Storms in Aurora Borealis Tourism

While solar storms can pose challenges for technology and infrastructure, they also create opportunities for Aurora Borealis tourism. The increased intensity and frequency of the Northern Lights during solar storm events can attract more visitors to popular Aurora Borealis viewing destinations, such as Iceland, Norway, Finland, and Canada.


Many tour operators and hotels in these regions offer specialised Aurora Borealis viewing packages and alerts, allowing tourists to maximise their chances of witnessing the Northern Lights during solar storm periods. Some companies even provide "Aurora Borealis chaser" services, where experts guide visitors to the best locations for viewing the Aurora Borealis based on real-time solar activity and geomagnetic data.


However, the unpredictable nature of solar storms and their effects on the Aurora Borealis can also lead to disappointment for tourists who travel long distances to see the Northern Lights but encounter unfavourable weather conditions or weaker-than-expected displays.


As solar storm forecasting and Aurora Borealis prediction methods continue to improve, the Aurora Borealis tourism industry may become better equipped to manage visitor expectations and provide more reliable Northern Lights experiences, even during periods of high solar activity.
