Initial Report


05JUN/2014 Matt Bellvue, CO 9:21pm MST 8-10? S to N, Facing East, R to L white, red hue at peak Brighter than Venus. large trail but no frags observed very flat trajectory. Tried for photo, too quick.

05JUN/2014 Ben Weeks Livermore Colorado USA 21:22 - 9:22 pm MT 3 seconds? east to west I was loking north Huge Fireball falling star, largest I have ever seen by far, maybe ten percent of the size of the full moon relative to my perspective. I am in lnorth east Colorado 30 miles from Wyoming it was north of me traveling east to west Very very bright the size and the distint fireball surrounding were nothing like I have ever seen and I am 50+. I could see the large object (bolide?) and the gren fire swirling around it!The object was actually darker the fireball bright as the moon. I have never seen the swirls of the fireball before or anything this big. No fragmentation Incredible. I will never forget it.

05JUNE2014 Chris Perry Loveland 2224 MT Pm 5-7 seconds right/left northwest right to left northeast pink/blue no sound moon none observed none

05JUN2014 Dane Andersen Sioux Falls, SD, USA 10:00PM (UTC-06:00 15 sec SE-NW facing West Orange sparkling tail, no sound About the same as the moon. Yes, there was a tail. This is my first supposed meteor sighting, so I hope I'm not way off. I was awestruck, so I had to go somewhere to learn more. I haven't seen anything quite like it before, with its particular size, speed, distance, and appearance. Educate me if I'm full of shit!

A series of All-Sky (fish eye) images showing the plasma trail left by a fireball, which extends 92 degrees across the northern half of the sky. These images are 5 second snapshots captured at 37.8 MHz with the LWA1 radio telescope. The bright steady sources (Cygnus A, Cassiopeia A, the galactic plane, etc) have been removed using image subtraction. See Animated Image Here
At any given moment, it seems, the sky is sizzling with celestial phenomena waiting to be stumbled upon. New research using the Long Wavelength Array (LWA, a collection of radio dishes in New Mexico, found quite the surprise. Fireballs - those brilliant meteors that leave behind glowing streaks in the night sky - unexpectedly emit a low radio frequency, hinting at new unexplored physics within these meteor streaks.

The LWA keeps its eyes to the sky day and night, probing a poorly explored region of the electromagnetic spectrum. It's one of only a handful of blind searches carried out below 100 MHz.

Over the course of 11,000 hours, graduate student Kenneth Obenberger from the University of New Mexico and colleagues found 49 radio bursts, 10 of which came from fireballs.

Most of the bursts appear as large point sources, limited to four degrees, roughly eight times the size of the full Moon. Some, however, extend several degrees across the sky. On January 21, 2014, a source left a trail covering 92 degrees in less than 10 seconds (see above). The end point continued to glow for another 90 seconds.

Dr Andy Tomkins says meteorites can been seen hundreds of kilometres away from ground level.
Dr Andy Tomkins is a Senior Lecturer at the School of Geoscienes at Monash University.

He says there were reported sightings of a loud, white flash at ground level at around 6:30pm on the worldwide meteorites news website.

"It would have been a meteorite coming in somewhere from Mars and Jupiter, they usually come from that sort of orbit, and just coming through our atmosphere really, really fast and burning up as it came through the atmosphere and hopefully landing on the ground."

Dr Tomkins encourages people to check their CTTV cameras from Sunday evening in hope of locating the meteorite.

"We can use that to figure out the direction that the meteorite came from and where it's likely to have ended up on the ground, particularly if there is some sort of time stamp on the video that really helps us nail it down as well."

"We use video from multiple directions from where people have seen it from multiple angles to triangulate down toward the ground position."

He says people who heard a loud bang on Sunday evening would have been within close proximity to its landing.

"Usually it gets brighter the closer you are to it, then a bang, the boom people heard is when you're really close to it, people can usually see a smoke trail if they're fairly close."

Massa describes the damage to his car after an impact around 2 a.m. Sunday.
Dayton - A Kettering man believes a meteorite hit his car early Sunday morning. Joe Massa said he was driving home in the center lane on I-75 North when his Buick was struck by something around 2 a.m.

Out of the corner of his eye, he said, "I could see something. It was a light, shadow, a beam of light, small. Within a split second, something hit me, the front of the car was pushed over into the far left lane."

Massa said there was a big flash when it hit.

"It was like a silent pop," Massa said, "then there was pressure in the car. I could feel pressure in my ears, like the air had changed in the car, in a split second."

Massa, who manages restaurants in the Cincinnati area, said he pulled over immediately to see if he hit a deer, a dog, or something else. He found nothing, except the damages to the right-front bumper.

New potentially hazardous asteroid 2014 KP4

The MPEC 2014-K35 issued on May 23, 2014 announced the discovery of a new PHA asteroid officially designated 2014 KP4. This asteroid (~ magnitude 16) was discovered by C. Jacques, E. Pimentel & J. Barros through a 0.20-m f/2.2 Schmidt-Cassegrain + CCD telescope of SONEAR Observatory (MPC code Y00), on images obtained on May 20.2, 2014.

According to the preliminay orbit, 2014 KP4 is an Apollo type asteroid. This class of asteroids are defined by having semi-major axes greater than that of the Earth (> 1 AU) but perihelion distances less than the Earth's aphelion distance (q < 1.017 AU). It is also flagged as a "Potentially Hazardous Asteroid". PHA are asteroids larger than approximately 100m that might have threatening close approaches to the Earth (they can come closer to Earth than 0.05 AU).

2014 KP4 had a close approach with Earth on May 11, 2014 at rougly 26.2 LD (Lunar Distances = ~384,000 kilometers) or 0.0673 AU (1 AU = ~150 million kilometers).

We performed some follow-up measurements of this object on 2014, May 20.6, remotely from the Q62 iTelescope network (Siding Spring) through a 0.50-m f/6.8 astrograph + CCD + focal reducer. Below you can see an animation showing the fast movement (the object was moving at 6.5 "/min) of 2014 KP4 on the the sky on May 20, 2014. Each frame is a single 15-second exposure.

'First time' meteor shower may light up skies over North America this weekend

Will the May Camelopardalids light up the sky or will it get pulled out of Earth's proximity by Jupiter's gravity?

North America is in for a natural light show overhead, as a meteor shower expected over the weekend could turn into a full-on sky storm, affecting countries' entire skylines. Its intensity could even outdo the Perseid meteor shower.

Stargazers are expecting the spectacle to hit late Friday and last into Sunday morning, just as Earth passes through a stream of debris consisting of up to 1,000 pieces of a comet it shed in the 1800s falling all around, every hour, at speeds of 12 miles per second (19.3kps).

The so-called May Camelopardalids will peak at about 2am to 4am on Saturday, eastern US time, according to Bill Cooke of the Meteoroid Environmental Office at NASA's Marshall Space Flight Center. The name comes from the corner of the sky where we'll have to focus our gaze to see the shower's most prominent bits - the Giraffe constellation, right next to the North Star.

The blue map follows their position in the sky using the Canadian Meteor Orbit Radar (CMOR). The main showers are highlighted with circles and listed by their International Astronomical Union name. A second radar map on the bottom looks at meteoroid speed.
* Maps produced using the space agency's Asgard program which tracks an estimated 4,000-5,000 meteoroids a day

* Every day, more than 40 tonnes of meteoroids hit our planet, with larger chunks of comet debris becoming fireballs

* The blue map tracks their position in the skies over our planet with the main showers highlighted in white circles

* A second radar map looks at meteoroid speed. The red regions indicate a speed of 7.5 miles/s (12km/s), the green from 26 miles/s (42km/s) and the blue from 41 miles/s (66km/s)

Every day, more than 40 tonnes of meteoroids hit our atmosphere.

Many are tiny specks of comet dust that crumble harmlessly in Earth's atmosphere, producing a slow drizzle of meteors in the night sky.

Bigger chunks of asteroid and comet debris create dozens of nightly fireballs around the planet - and now, these real-time maps mean you'll never have to miss one again.

Nasa's meteoroid visualisations are produced using the space agency's Asgard software program which tracks an estimated 4,000-5,000 meteoroids a day.
