Rare meteor shower may 'outburst' on June 11

The rare and rarely heard of meteor shower called the Gamma Delphinids will appear to radiate from the constellation Delphinus (del-FINE-us) the Dolphin high in the southern sky shortly before dawn tomorrow morning June 11. This map shows the sky facing south at 3:30 a.m. local time. Delphinus is near the bottom of the bright 3-star figure the Summer Triangle.
Back on June 11, 1930 three members of the American Meteor Society (AMS) in Maryland saw a half-hour-long bright outburst of meteors from the little constellation Delphinus the Dolphin. No one had predicted the shower, but it came out of nowhere and hasn't been seen since. Attempts to catch a repeat performance in subsequent years met with no success.

That may change tomorrow morning, June 11, 2013. Peter Jenniskins, research scientist with the SETI Institute and NASA Ames Research Center, has examined dust outbursts from long-period comets and suggests the Gamma Delphinids may return for a brief moment of splendor, as Earth passes through this stream of cometary debris not seen since 1930.

The fire service attended a report of an "explosion" in Castle Street
Three "explosions" heard in the early hours of the morning in Northampton are being treated as unexplained.

Northamptonshire Fire Service investigated the separate reports in St Mary's Street, Castle Street and Silver Street but "didn't find anything".

Andy Gineikis, who lives nearby, said he heard a "loud bang" similar to a shotgun blast at about 03:30 BST.

Western Power Distribution said there had been a power cut in the Abington area of Northampton at about 04:40.

June Arietids - The invisible meteor shower you just might see

I've never seen an Arietid meteor and chances are you haven't either. Peaking on June 7-8, the Arietid (AIR-ee-uh-tid) meteor shower is one of the strongest of the year with a maximum rate of 50-80 per hour. But there's a rub. The shower radiant, the point in the sky from which the meteors appear to radiate, is near the sun and best seen during daylight hours. When was the last time you saw meteors in daylight?

If you're wondering how anyone could discover a meteor shower when the sun is out, it's impossible unless your eyes can see radio waves. The Arietids were first "seen" in 1947 by operators of radio equipment at Jodrell Bank Observatory in England. Meteors leave trails of ionized gases when they rip through our upper atmosphere at tens of thousands of miles per hour and briefly make ideal reflectors of radio waves.

Did you hear a big boom in the area of Smyrna, Tennessee Monday night?

WGNS has received multiple phone calls and emails from residents in the area of Smyrna telling us that they heard a loud "BOOM" sound Monday night. The sound was heard around 8:30 in the evening.

WGNS checked with the Smyrna Police Department where we talked to Police Chief Kevin Arnold. Arnold told us, "We received several complaints last night about that. The Sheriff's Office also received complaints. From the log this morning it appears nothing was found."

We then headed to the Smyrna / Rutherford County Airport. There, we were told that no "BOOM" sounds involving airplanes were reported on Monday night. Several workers there told us they did not hear the "BOOM."

So that leaves us with the big question... What was that big "BOOM" sound that was heard Monday? It seems as if we cannot find the answer to that mystery.

Crashed asteroid has a tail that keeps getting longer

A strange comet-like object discovered in 2010 ended up being an asteroid that had been the victim of a head-on collision from another space rock. The object created a bit of buzz because of its mysterious X-shaped debris pattern and long, trailing streamers of dust. Named P/2010 A2 (LINEAR), the object is located in the asteroid belt between Mars and Jupiter, and has been the focus of much study, including images taken by the Hubble Space Telescope and many ground-based observatories. But over time, the asteroid's long dust tail has grown to be so long that the entire object can't fit into the field of view of most observatories.

"Here, we are watching the death of an asteroid," said Jayadev Rajagopal, a scientist at the WIYN (Wisconsin Indiana at Yale NOAO) Telescope, speaking today at the American Astronomical Society meeting in Indianapolis, Indiana. "We know of dozens of asteroids this has happened to in the past, but this is the only one showing us the event as it is happening."

Using the new wide-field camera at the WIYN 3.5 meter telescope, Rajagopal and his team have found that the peculiar asteroid P/2010 A2′s tail is much longer than was previously supposed. The tail is about a million kilometers long, roughly three times the distance from the Earth to the Moon. The new One Degree Imager (ODI) can currently image an area of the sky about the size of the full moon: a future upgrade will increase the size of the field to about four times as large.

Meteor spotted over Florence, South Carolina

Florence - If you saw what is described as a "fireball" around 11:05 p.m. last night, you were not alone.

The Recorder received a report about a meteor flying over Florence last night. According to the American Meteor Society, more than 50 witnesses reported a large fireball meteor over Ohio May 30.

The fireball was seen primarily from Ohio and Indiana, but witnesses from Kentucky, West Virginia, Virginia, Pennsylvania and North Carolina also made reports.

The society has developed technology that can plot the path of any fireball reported to their system. According to amsmeteors.org, the accuracy of these paths is dependent on the number of witnesses who report the event and their distribution around the fireball.

This particular event provided a large volume and good geographic distribution of witnesses.

The society urges witnesses of the fireball to fill out an official report with them. Visit their website to do so.

Extremely large meteor lights up skies over Finland, booms heard

The fireball was captured by a photographer in Mikkeli, eastern Finland.
An unusual light and sound phenomenon that was sighted in Finnish skies in early May has been confirmed as a fireball, in other words a very bright meteor. The light was seen on May 8th in parts of southern and central Finland.

The Ursa Astronomical Association confirmed that a bright light and loud boom seen and heard by almost 300 Finnish citizens on May 8th was a meteor. The space rock was estimated to be about half a metre long and weighing 50 kilos.
