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 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.

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.”

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.

MORE than 2,000 residents have been evacuated in 30 barangay (villages) in three northern Cagayan towns, with a 60-year-old male farmer missing and believed to have drowned during widespread flooding brought about by heavy downpours Maj. Stanley Banan, Sanchez Mira town police chief, said teams conducted rescue operations in flooded areas and for Artemio Bumiltac, who reportedly was trying to save his carabao from his rice field when he was swept by a flash flood on Saturday around 5 p.m. in Barangay Santiago.
Banan added that Bumiltac’s carabao had been rescued but its owner has not yet been seen by Santiago residents where more than 100 of them were also evacuated to higher grounds and brought to five evacuation areas in Sanchez Mira.
He said the rescue teams transferred more residents from 14 villages and low-lying areas in the town where houses were already submerged by floodwaters.
Cagayan Gov. Manuel Mamba said the towns of Claveria, Pamplona and Santa Praxedes had been affected by flash floods and landslides, making roads and bridges not passable.
Most of the more the 2,000 evacuees were from 30 villages in Claveria with 1,400 individuals, followed by Santa Praxedes with 850 and the rest from Sanchez Mira and Pamlona towns.
The provincial Task Force Lingkod Cagayan (TFLC) reported that a bridge in Santa Praxedes had been damaged by floodwaters, which submerged parts of the national highway in Claveria, Pamplona and Sanchez Mira.
The task force said Daang Maharlika (national road) in Calvaria going to Santa Praxedes remained not passable as of Monday.
Mamba said the TFLC had teamed up with the Philippine National Police and the Philippine Marine Battalion Landing Team-10 in the rescue operations of residents and livestock in the province.

Sydney has been plunged into chaos after severe weather swept through the state, causing flash flooding and triggering a landslide at a remote walking trail in the city’s north.
Aerial footage shows the land spill at the Mackerel trail near Palm Beach that came within metres of several properties and caused severe damage to at least one home at Mackerel Beach.
Another two properties were “partly” damaged.
Residents at 18 addresses – totalling 25 people – have been evacuated, while officials at the Northern Beaches Council have been called in to assess the damage, a NSW SES spokesman said.
Sydney’s Northern Beaches have already copped 100mm of rain in the last three days with more on the way as flash flooding prompted road closures and left many homes without power.
The news comes as Australia’s east coast battles a hammering from mother nature.
Australia has been hit by more than 2.24 million lightning strikes in just 48 hours, while damaging winds of up to 100km/h continue to rip through multiple states, with volunteers inundated with calls for help.
More storms are expected this week.
“This is peak storm season,” BOM meteorologist Dean Narramore said.
Sydneysiders can expect the storms to hit on Tuesday and Wednesday, with the peak predicted for the latter.
