The mesmerizing phenomenon of the Northern Lights, also known as the Aurora Borealis, has been captivating people all around the world. This natural light display in the Earth’s sky is usually seen in high-latitude regions, particularly near the Arctic Circle. However, in recent years, there has been an increase in the frequency of sightings of the Northern Lights even in regions that are not typically known for such displays, like the United States.
But why are we witnessing the Northern Lights more often now? According to astronomers, the current uptick in Northern Lights sightings is linked to the sun’s 11-year cycle, with the sun currently being at its “maximum” phase. This 11-year cycle of the sun involves periods of high and low solar activity, with the sun reaching its most active and turbulent phase at the peak of the cycle.
During the solar maximum, the sun experiences frequent and intense solar flares and eruptions. This heightened solar activity leads to an increase in the number of sunspots on the sun’s surface. These sunspots are regions of strong magnetic activity that can produce Coronal Mass Ejections (CMEs) – bursts of charged particles that are released into space.
When these charged particles interact with Earth’s magnetic field and atmosphere, they create the stunning light show known as the Northern Lights. The collision of these particles with atmospheric gases results in the emission of light at different wavelengths, producing the colorful dancing patterns in the sky that we associate with the Aurora Borealis.
The recent surge in Northern Lights sightings can be attributed to a large sunspot eruption that occurred on the sun’s surface in October. This eruption sent a stream of charged particles towards Earth, creating optimal conditions for the Northern Lights to be visible even in regions further away from the Arctic Circle.
Experts predict that the current period of increased solar activity will persist for months, leading to more frequent occurrences of the Northern Lights in various parts of the world. During this time, individuals are advised to seek out dark areas away from artificial light and be in a cloud-free location for the best viewing experience.
The 25th 11-year solar cycle since 1755 is set to begin in 2019, with the peak of solar activity expected to occur next year. With the sun’s magnetic poles flipping during this period, we can anticipate more intense and frequent displays of the Northern Lights in the near future.
In conclusion, the recent increase in Northern Lights sightings can be attributed to the heightened solar activity associated with the sun’s 11-year cycle. As we continue to experience the peak of this cycle, we can look forward to more opportunities to witness this breathtaking natural phenomenon in the night sky. So, keep your eyes peeled and be prepared to be amazed by the beauty of the Northern Lights.
