Early morning fireball over St. George, Utah

St. George — Reports came in to the Utah Highway Patrol Cedar City Dispatch Center Friday describing a fireball streaking across the sky south of SunRiver St. George just before 7:30 a.m.

A fireball occurs when a meteor enters Earth's atmosphere and burns brightly before being consumed by the fire, and is defined by the American Meteor Society as an object that is brighter than the planet Venus.

The American Meteor Society received reports from three observers in Lake Havasu City, Arizona, Flagstaff, Arizona, and Pahrump, Nevada, of a fireball about the same time as the Southern Utah sighting. San Diego-based Robert Lunsford, the report coordinator for the AMS, said it was probably the same object, but it likely burned up in the atmosphere before hitting the ground.

Bright meteor seen from Puerto Rico

A bright meteor was seen from Puerto Rico on the night of August 20, according to Sociedad de Astronomía del Caribe (SAC). The largest astronomy organization on the Caribbean Island says the meteor was seen at about 9:30 p.m. local time. "We got reports from the north and west side of the Island, but it is possible the meteor was also seen from other areas of Puerto Rico, SAC said.

Large bolide seen over eastern Norway

Meteor seen from Harestua.
The activity of meteor swarm Perseids is at its greatest these days and several in Eastern Norway who were up in the night to see meteors, got a great experience.

A large bolide appeared 1:50:39 and lit up the night. It shone like the brightest full moon, was yellow-green in color, some also described it as blue and white, and was visible for 8-9 seconds. However, this was not one Perseid. Over parts of eastern Norway found the admittedly coming from Perseus, but it is a random perspective effect. It was slower and lasted much longer than any Perseid, and seen from elsewhere, it went in a different direction from Perseus.


Question

Could a meteorite have started the fire in Portland, Oregon man's front yard?


Patrick Story says the burned patch in the front yard of his Southeast Portland home lines up with a singed portion of a nearby bush.
A Southeast Portland man thinks a meteor might have caused a mystery fire in his front yard.

Patrick Story says he heard a loud boom outside his house on Wednesday night, coupled with a flash of light.

When he went outside, he found part of his front yard on fire in the shape of a circle.

Firefighters told him the fire was "naturally-caused," however they couldn't find any fragments. Story thinks it was a fallen meteorite.

"Because the bush was set on fire, you can kind of think there was a trajectory of something flying through the air," said Story. "Since it was the night of the Perseid Meteor Shower... you got to wonder."

Comment: This is a sad display of what a scientist thinks about meteors. Hopefully this is not representative of the profession in general. Yes, space is cold, yet how can a scientist given the recent well publicized meteor over Chelyabinsk, Russia and the many examples of meteors entering the atmosphere, burning up and exploding come to the conclusion that "they're simply too cold" in all instances? From an expert in the field, mind-boggling!

Pray tell, how did this meteor, which was obviously larger than a bb, light up the sky on Wednesday night during the Perseid shower?

This photo shows a fireball shooting over London, Ont. on Aug 12.
Video released by Western University shows a bright fireball that quickly lit up the sky over London, Ont., on Wednesday night during a Perseid event.

According to Peter Brown, a professor with the department of physics and astronomy at Western University, the fireball was travelling at around 60 km per second.

Brown says the object was only about the size of a loonie but because of its immense speed, it was visible with the naked eye from Earth for about 1.5 seconds.

"At this speed, the fireball has the same amount of energy as 400 times its weight in dynamite," Brown said.

"The fireball was bright, much brighter than Venus and any other object in the sky. It was comparable to a half moon," Brown added.

Nasa video of Perseid fireball over New Mexico

Perseid fireball over the skies of New Mexico
Video observed by the Nasa All Sky Fireball Network shows the Perseid fireball over the skies of New Mexico on the morning of August 12.

August 12 and 13 were the two days when the Perseid shower was set to peak, with a huge array of meteors visible. The meteor shower was not just visible in the US but across the world, including the UK, with stargzers in the Midlands and the North having the best view of the meteors as cloud cover meant visibility was limited across southern England and Scotland.

The Perseids this year coincided with a new moon - for the first time since 2007 - creating the ideal dark sky conditions.

The meteors reached their peak on Wednesday and Thursday night when over 100 per hour were produced.

August's annual Perseid meteor shower is expected to peak on Wednesday, with a special weather permit and perfect lunar conditions, coming just one day before the new moon.

Astronomers hope that the meteor shower, which falls in the middle of the week this year, is going to be really special. The celestial conditions will differ from last year's, when a bright moon faded the colors of the shooting stars.


Comment: A light show worth watching!

Loud explosion and large glowing object in the sky reported from Tamworth, Australia

Image

City of Tamworth NSW, Australia
This morning, local Tamworth police took a number of phone calls reporting an explosion, houses shuddering and they posted the following on the Oxley Local Area Command Facebook Page:

"About 1.30 am on Tuesday 11th August 2015 Police received numerous calls from Tamworth residents in relation to a loud explosion heard in many different parts of Tamworth. Residents reported their houses seemed to shake with the noise. No-one was able to accurately describe a location for the explosion. No reports of fire were received. Police patrolled several areas of Tamworth in response to these calls however no damage was located.
The mystery appeared solved about 30 minutes later when a local taxi driver contacted Police and reported sighting a large glowing object in the sky trailing a green tail fall to earth somewhere to the south of Tamworth City. At this time, it is believed the explosion can be attributed to the unknown falling object, possibly a meteorite."

Intrigued, I sent this to our resident astronomer Astro Dave Reneke. He knew exactly what this was, a sonic boom, the result of a fireball from a meteor shower... quite rare, listen to the explanation here: Astro Dave with Anna Moulder on ABC NENW Breakfast

Officials in Iran have confirmed that a meteor has hit somewhere in the northern part of the country on July 30, 2015. The event happened a day before a very large fireball streaked over the sky of Argentina.

According to Mohammad Ali Ahani, director of Qazvin Crisis Management Staff, the meteor landed in Avaj, province of Qazvin. There are reports that some pieces of the rock have hit areas in Eshtahard, Alborz Province.

Many Iranian news agencies speak of serious damage to Qazvin, which is located not too far from the state capital, Tehran. Injured or victims have not been confirmed, but such rumors are circulating on the Internet.

Reports of damage come from multiple locations.

Iranian newspapers say the meteor was very large (could be more than two meters long) because there are numerous towns affected by the impact, with shattered windows and damaged fixtures.
