Many Lake City folks were able to marvel at a dynamic light show last week. The “show” was the result of a highly active Aurora Borealis.
The Aurora Borealis, known as also as the Northern and Southern lights, are a result of a strong surge of energy and particles from our Sun. This phenomenon, commonly known as the “solar wind” begins on the Sun’s outer atmosphere. At times, huge explosions of energy take place which are known as “coronal mass ejections or CME.” CMEs eject energy out into our solar system and, as a result, some solar winds take a direct path towards Earth.
When they arrive here, Earth’s magnetic field shields us from much of this storm. However, some are so powerful that some particles journey down the magnetic field lines and into Earth’s atmosphere. When this occurs, a glow of colorful (red, green, violet, blue) light can be seen on Earth; the Aurora Borealis can only be seen in upper latitudes of such places as Alaska, Iceland, Scandinavia, Canada, etc.
However, a powerful CME was strong enough to cause sightings throughout the United States and as far south as Texas! In Lake City, the CME was especially powerful on the evenings of October 9 and 10th. Several Lake Citians posted their Aurora experience on Facebook. Kathleen Whinnery, Michelle Cogger, Amanda Hartman, Katie Elkins, Michael Underwood, and others took beautiful pictures of the Aurora with most showing the dominating color of red. The Aurora was so strong that it could be seen not only in the north but also in the west, east, and southern skies.
Our Sun goes through cycles of calm and stormy activity. This year, the stormy activity has been quite vigorous. As early as April, the Aurora was seen by the Elkins family at Windy Point. Forecasts for more energetic CMEs are for the phenomenon to continue through this year and all of 2025.
The downside of Auroras on Earth is that they can play havoc with satellites, radio communications, and electronics. Blackouts can shut down cities for hours.
There are many sources to get more information and forecasts for the Aurora Borealis such as www.spaceweather.com, www.swpc.noaa.gov, www.spaceweather.gov. www.spaceweatherlive.com.
If you go out to see the Aurora, you may notice a bright white glow but no colors. This is because our human eyes are limited in detecting colors at these times. Fortunately, a cell phones camera can pick up these colors. The best photos are placing your phone on a stable surface, turning off the flash, and setting exposure of about 3 seconds.
Is This The “New Normal”
No measurable precipitation for three weeks…no low temperatures below 32 in September…average median temperature for September, 2024 was two degrees above the historical average…flowers still blooming and grass still green this month…aspens were brilliant this year but were latent in taking place but lasted well into October…and, for this October so far, our average high is 72 compared to 59.5 historical average and 36 low compared to 25.6 historical average!
As a National Weather Service observer for four decades, this trend is not surprising to me as I have witnessed this gradual warming up of September for the last several years. Additionally, we have seen these long stretches of three to four weeks of little or no precipitation.
Will this trend continue? If so, should the Lake City business and the Chamber address this by actively promoting early fall tourism through mid-October?
Unfortunately, I do not have the crystal ball for such a long-term outlook for our weather. Nevertheless, based upon my observations (especially over the last fifteen years), there is a change in our September and early October climate.
