Two bright fireballs flashed over the Prairies, almost exactly one night apart – The Weather Network

Published

 on


They came from completely different parts of the sky. Still, one night apart — nearly down to the minute — two bright meteor fireballs flashed over the Prairie provinces this week.

At 9:48 p.m. Central Time, on the night of Tuesday, March 22, witnessed spied a very bright meteor streaking across the sky.

According to the American Meteor Society, the fireball began around 40 kilometres north of Erwood, SK, just east of Highway 9 in the eastern part of the province. Then, for about 5 seconds, it blazed towards the southwest before winking out at a point just west of Fosston, SK, nearly 200 kilometres away.

Based on witness reports, the event was seen as far away as North Dakota, southern Manitoba, and northern Saskatchewan. Even someone from the village of Empress, on the border between Saskatchewan and Alberta, spotted it.

Storm spotter Nick Schenher captured the fireball on his front door camera from Regina, SK.

If that wasn’t amazing enough, the very next night, on Wednesday, March 23, at nearly the same exact time — 9:47 p.m. CT — a second meteor fireball was spotted.

Unlike the one from the previous night, this meteoroid appeared to plunge almost directly downward from space. Based on this, it was entirely unrelated to Tuesday night’s fireball, as the two originated from different points in space.

Alix and Jason Cruickshank caught this one on video from their home in Winnipeg, MB.

Fireballs like this are caused when pieces of rock or ice (meteoroids) plunge into Earth’s atmosphere from space, travelling at speeds of up to hundreds of thousands of kilometres per hour. As it ploughs through the upper atmosphere, a meteoroid compresses the air in its path, which heats the air up so much that it glows. This results in the meteor flash we see in the sky. Given that they occur at altitudes of 50 to 80 km above the ground, a particularly bright flash is typically visible for hundreds of kilometres around.

The meteor flash ends either when the meteoroid is completely vaporized by the heat or when the meteoroid slows enough that it can no longer compress the air to the point of incandescence.

WHAT ARE THE ODDS?

Seeing Tuesday night’s meteor fireball was rare enough.

“A fireball this big and bright is exceptionally rare for a person to see,” Scott Young, the planetarium astronomer at the Manitoba Museum, told CBC Manitoba on Wednesday.

“If you’re a devoted sky watcher and you spend your whole life, you might be lucky to see two. But I mean, it really is a once-in-a-lifetime event.”

Witnessing two fireballs from the same location, on two nights in a row… that has to be exceptionally rare. Right?

Based on the American Meteor Society reports, only one person of the 45 witnesses who saw the Tuesday night fireball — Trevor Bryant, from Brandon, MB — also managed to spot evidence of the Wednesday night event.

Bryant’s webcam captured a great view of the first fireball (embedded below). However, it only managed to record an extremely brief flash of light from the second, as the meteor occurred outside the camera’s point of view.

Witnessing a fireball isn’t just a matter of being outside and looking up.

Fireballs occur randomly, so they can happen at any time (but more on that below). First, it needs to be dark enough to see it, or the fireball has to be bright enough to spot in the light of day. Second, your timing of exactly where you are looking needs to be spot on. These events are here and gone in just a matter of seconds. So, even looking down at your cellphone, turning your head to talk to someone, or moving so a building or trees suddenly block your view of that exact part of the sky could cause you to miss it. Third, you actually need to be able to see the open sky. Clouds in the area could cause even a super-bright fireball to go unnoticed.

So, seeing two meteors like this, almost exactly one night apart, is remarkable.

However, according to Denis Vida, a meteor physics postdoctoral researcher at Western University, the timing of these two may not be all that rare after all.

In an email to The Weather Network, Vida pointed to research written back in 1982 by Canadian meteor astronomers Ian Halliday and Arthur Griffin.

In their paper, Halliday and Griffin gathered what we knew at the time about where meteorites come from — the typical orbits that meteoroids follow around the Sun before they hit Earth. They then used that information to determine when we are most likely to see these meteorite falls, based on the season, the time of day, and our latitude.

Summing up the results, Vida said that “we’ll observe the greatest number of falls during the spring, between sundown and 12 a.m.”

Given that we are just days after the spring equinox, Vida added, we are right at the peak of yearly meteorite fall activity. Plus, when these two fireballs were seen, right around 9:47 p.m. local time, is also right around the peak time of day for this latitude on Earth.

COULD THERE BE METEORITES?

The typical meteor flash in the sky is caused by a micrometeoroid — probably about the size of a grain of sand — which tends to completely vapourize when it hits the atmosphere. Bright fireballs like these two, on the other hand, are produced by larger objects. The larger a meteoroid is, and the slower it travels through the atmosphere, the greater the chance that part of it could survive to reach the ground.

That’s when there’s a possibility of finding meteorites.

According to Vida, simply based on how long the two fireballs last, it’s possible that perhaps around 100 grams of meteorites may have hit the ground from each. However, more analysis would be necessary to know for sure.

Finding meteorites in Canada is often quite difficult, though. Snow on the ground can make this easier. The scorched black exterior typical of meteorites stands out quite well against the white surface. However, in areas with plenty of trees and underbrush, locating them can be a challenge.

If you think you may have found one, here’s what to look for:

  • Look for the black exterior, the “fusion crust” that develops due to the heat from its passage through the atmosphere
  • See if it is magnetic. Even an ordinary fridge magnet will tend to stick to a meteorite
  • Beware of ‘meteor-wrongs’ such as industrial slag, which can have some characteristics of meteorites but are definitely from here on Earth.

Did you see either of these bright fireballs? If so, report what you witnessed to either the American Meteor Society or the International Meteor Organization. Every eyewitness report helps refine the path of these meteors, improve the science of meteors and fireballs, and potentially even help locate meteorites for study.

Here’s how Helene and other storms dumped a whopping 40 trillion gallons of rain on the South

Published

 on

 

More than 40 trillion gallons of rain drenched the Southeast United States in the last week from Hurricane Helene and a run-of-the-mill rainstorm that sloshed in ahead of it — an unheard of amount of water that has stunned experts.

That’s enough to fill the Dallas Cowboys’ stadium 51,000 times, or Lake Tahoe just once. If it was concentrated just on the state of North Carolina that much water would be 3.5 feet deep (more than 1 meter). It’s enough to fill more than 60 million Olympic-size swimming pools.

“That’s an astronomical amount of precipitation,” said Ed Clark, head of the National Oceanic and Atmospheric Administration’s National Water Center in Tuscaloosa, Alabama. “I have not seen something in my 25 years of working at the weather service that is this geographically large of an extent and the sheer volume of water that fell from the sky.”

The flood damage from the rain is apocalyptic, meteorologists said. More than 100 people are dead, according to officials.

Private meteorologist Ryan Maue, a former NOAA chief scientist, calculated the amount of rain, using precipitation measurements made in 2.5-mile-by-2.5 mile grids as measured by satellites and ground observations. He came up with 40 trillion gallons through Sunday for the eastern United States, with 20 trillion gallons of that hitting just Georgia, Tennessee, the Carolinas and Florida from Hurricane Helene.

Clark did the calculations independently and said the 40 trillion gallon figure (151 trillion liters) is about right and, if anything, conservative. Maue said maybe 1 to 2 trillion more gallons of rain had fallen, much if it in Virginia, since his calculations.

Clark, who spends much of his work on issues of shrinking western water supplies, said to put the amount of rain in perspective, it’s more than twice the combined amount of water stored by two key Colorado River basin reservoirs: Lake Powell and Lake Mead.

Several meteorologists said this was a combination of two, maybe three storm systems. Before Helene struck, rain had fallen heavily for days because a low pressure system had “cut off” from the jet stream — which moves weather systems along west to east — and stalled over the Southeast. That funneled plenty of warm water from the Gulf of Mexico. And a storm that fell just short of named status parked along North Carolina’s Atlantic coast, dumping as much as 20 inches of rain, said North Carolina state climatologist Kathie Dello.

Then add Helene, one of the largest storms in the last couple decades and one that held plenty of rain because it was young and moved fast before it hit the Appalachians, said University of Albany hurricane expert Kristen Corbosiero.

“It was not just a perfect storm, but it was a combination of multiple storms that that led to the enormous amount of rain,” Maue said. “That collected at high elevation, we’re talking 3,000 to 6000 feet. And when you drop trillions of gallons on a mountain, that has to go down.”

The fact that these storms hit the mountains made everything worse, and not just because of runoff. The interaction between the mountains and the storm systems wrings more moisture out of the air, Clark, Maue and Corbosiero said.

North Carolina weather officials said their top measurement total was 31.33 inches in the tiny town of Busick. Mount Mitchell also got more than 2 feet of rainfall.

Before 2017’s Hurricane Harvey, “I said to our colleagues, you know, I never thought in my career that we would measure rainfall in feet,” Clark said. “And after Harvey, Florence, the more isolated events in eastern Kentucky, portions of South Dakota. We’re seeing events year in and year out where we are measuring rainfall in feet.”

Storms are getting wetter as the climate change s, said Corbosiero and Dello. A basic law of physics says the air holds nearly 4% more moisture for every degree Fahrenheit warmer (7% for every degree Celsius) and the world has warmed more than 2 degrees (1.2 degrees Celsius) since pre-industrial times.

Corbosiero said meteorologists are vigorously debating how much of Helene is due to worsening climate change and how much is random.

For Dello, the “fingerprints of climate change” were clear.

“We’ve seen tropical storm impacts in western North Carolina. But these storms are wetter and these storms are warmer. And there would have been a time when a tropical storm would have been heading toward North Carolina and would have caused some rain and some damage, but not apocalyptic destruction. ”

‘Big Sam’: Paleontologists unearth giant skull of Pachyrhinosaurus in Alberta

Published

 on

 

It’s a dinosaur that roamed Alberta’s badlands more than 70 million years ago, sporting a big, bumpy, bony head the size of a baby elephant.

On Wednesday, paleontologists near Grande Prairie pulled its 272-kilogram skull from the ground.

They call it “Big Sam.”

The adult Pachyrhinosaurus is the second plant-eating dinosaur to be unearthed from a dense bonebed belonging to a herd that died together on the edge of a valley that now sits 450 kilometres northwest of Edmonton.

It didn’t die alone.

“We have hundreds of juvenile bones in the bonebed, so we know that there are many babies and some adults among all of the big adults,” Emily Bamforth, a paleontologist with the nearby Philip J. Currie Dinosaur Museum, said in an interview on the way to the dig site.

She described the horned Pachyrhinosaurus as “the smaller, older cousin of the triceratops.”

“This species of dinosaur is endemic to the Grand Prairie area, so it’s found here and nowhere else in the world. They are … kind of about the size of an Indian elephant and a rhino,” she added.

The head alone, she said, is about the size of a baby elephant.

The discovery was a long time coming.

The bonebed was first discovered by a high school teacher out for a walk about 50 years ago. It took the teacher a decade to get anyone from southern Alberta to come to take a look.

“At the time, sort of in the ’70s and ’80s, paleontology in northern Alberta was virtually unknown,” said Bamforth.

When paleontogists eventually got to the site, Bamforth said, they learned “it’s actually one of the densest dinosaur bonebeds in North America.”

“It contains about 100 to 300 bones per square metre,” she said.

Paleontologists have been at the site sporadically ever since, combing through bones belonging to turtles, dinosaurs and lizards. Sixteen years ago, they discovered a large skull of an approximately 30-year-old Pachyrhinosaurus, which is now at the museum.

About a year ago, they found the second adult: Big Sam.

Bamforth said both dinosaurs are believed to have been the elders in the herd.

“Their distinguishing feature is that, instead of having a horn on their nose like a triceratops, they had this big, bony bump called a boss. And they have big, bony bumps over their eyes as well,” she said.

“It makes them look a little strange. It’s the one dinosaur that if you find it, it’s the only possible thing it can be.”

The genders of the two adults are unknown.

Bamforth said the extraction was difficult because Big Sam was intertwined in a cluster of about 300 other bones.

The skull was found upside down, “as if the animal was lying on its back,” but was well preserved, she said.

She said the excavation process involved putting plaster on the skull and wooden planks around if for stability. From there, it was lifted out — very carefully — with a crane, and was to be shipped on a trolley to the museum for study.

“I have extracted skulls in the past. This is probably the biggest one I’ve ever done though,” said Bamforth.

“It’s pretty exciting.”

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
