Huge Fireball Meteor over Alaska Sets off Volcano Warning System 360 Miles Away
A huge “fireball” meteor that lit up skies across west Alaska also set off newly installed sensors for detecting volcanic activity, the U.S. Geological Survey (USGS) has said.
The event, which took place on October 15, triggered six of the sensors’ alarms at a new monitoring station on the Kenai Peninsula. The sensors are built to detect low-frequency sound waves in the atmosphere during volcanic activity, but in this case they picked up waves coming from the meteor that had streaked across the sky around 360 miles away.
In a Facebook post, the USGS said the meteor also triggered an alarm at Mount Spurr—a large, active volcano that sits around 80 miles from Anchorage that last erupted in 1992. However, as other monitoring systems also picked up on the waves, “it quickly became clear that this was not activity at Mount Spur,” the post said.
Scientists with the USGS Alaska Volcano Observatory worked with researchers from the University of Alaska Fairbanks Geophysical Institute to investigate the cause. They found the meteor passed over Alaska around 40 miles from the Athabaskan community of Kaltag, which sits on the Yukon River.
In a blog post for the American Geophysical Union, UAF science writer Ned Rozell said witnesses reported the fireball in regions hundreds of miles apart. One resident of Ruby described it as an “enormous ball of light in the sky,” saying it was moving north to south. Another resident said it looked like “fireworks” that split into four dots.
David Fee, head of the infrasound program at UAF’s Geophysical Institute and researcher with the AVO, said he believes the meteor exploded somewhere east of Kaltag. “I typically don’t work on meteors, but they are often really nice infrasound sources to help better understand the performance of our networks, and I think provide valuable information on meteors and bolides themselves,” he said.

A Meteorite – Asteroid Passed Near Earth at Record Speed
A meteorite called 2020 UF3 passed at record speed from a point that could be considered quite close to our planet on October 22. The asteroid detected by the Virtual Telescope Project has passed only 42 thousand kilometers. This distance roughly corresponds to 11% of the distance between the Earth and the moon.
According to NASA reports, the speed of the asteroid was also very high. The 2020 UF3 was traveling at 22 kilometers per second. In other words, its speed was 79 thousand kilometers per hour. If the asteroid was orbiting our planet at full speed, it could have made almost 2 rotations per hour.
The asteroid also managed to become the fastest meteorite ever observed by this astronomy group, according to the Virtual Telescope Project. The team published an article on the subject on their website.
“The near-Earth asteroid 2020 UF3 has safely come very close to our planet, to a minimum distance of 42000 kilometers from Earth. It is about 11% of the average moon distance ”.
An image of the meteorite was also captured in the project. This image is not very clear. The object, which can be viewed for only 3 seconds by the Elena robotics unit, is a bit blurry and there are slight distortions in the image. Yet enough to witness the passage of the asteroid.
Despite being so close to Earth, the meteorite’s discovery took place only on October 21st. The reason for this is that the celestial body is a relatively small meteorite between 13 and 57 meters tall. The Lemmon Mountain research team discovered the asteroid.
From time to time, such small structures can go around our planet. In fact, the Sun and Jupiter greatly prevent such structures from hitting our planet thanks to their enormous gravitational field.

Several Colorado ski resorts get 10 inches of snow from weekend storm
Multiple Colorado ski resorts received 10 inches or more of fresh snow from a weekend storm that provided a boost to snowmaking efforts in the final week of October, usually a month when one or two areas are already open for the season.
No areas have opened yet, but Loveland and Arapahoe Basin are racing to become the first. Keystone, which also has been making snow, has been aiming for a Nov. 6 opening date.
Sunlight received 10-12 inches at the base, according to spokesperson Troy Hawks, adding that the bounty will be good for snowmaking there.
“Having the moisture on the lower mountain is just fantastic because man-made snow holds up better in the long term on top of moist frozen ground, verses dry frozen ground,” Hawks said. “The dryness draws moisture out of the man-made snow above it. When the ground is already moist, the man-made snow generally lasts longer into the season.”
At Winter Park, spokesperson Jen Miller said the snow stake was showing 11 inches at mid-morning and “it’s still snowing,” she said.
Eldora also received 11 inches, with another inch expected through the day, according to spokesperson Kyle Ogilvie.
Snowmass, Vail and Beaver Creek all received 10 inches, while Breckenridge and Keystone reported nine. Loveland got seven inches and Arapahoe Basin got six.
“We are expecting a little more snow to come in this evening,” said Arapahoe Basin spokesperson Leigh Hierholzer. “We definitely can use the precipitation to help recharge our reservoir.”

Snow Is Falling On October 26, 2020 in Kansas City, USA
A winter storm is bringing snow, sleet and freezing rain to Kansas – and that’s causing travel troubles and school closures.
USD 259 (Wichita) IS OPEN TODAY, but several school districts have called off class for today. They include Andover, Derby, Mulvane, Clearwater, El Dorado, Haysville and Rose Hill.
Valley Center and Maize both called off in-person classes. All students will be learning remotely today.
The Kansas Air National Guard is also on a 2-hour delay for non-essential personnel.
Roads are slick across the state. We are hearing of crashes all over Kansas. Thankfully, as of 6:30 a.m., we have not heard of any serious injuries from those crashes.
Give yourself some extra time before you head out the door this morning. Of course, if you can avoid driving this morning, it may be best to just stay home.
