Bright Sky Event Over Southeastern United States – June 29

Meteor across SEComposite image showing bright event located near Rosman, North Carolina.

There was a bright event seen across several Southeast states last night at 12:29:30 AM CDT (1:29:30 EDT). Based on the data we currently have, this object was not a meteor or fireball. Tracked by 5 NASA cameras in the SE, it is moving at roughly 14,500 miles per hour, which is too slow to be a meteor. As you can see in the video, it has also broken into multiple pieces, which, combined with the slow speed, indicates a possible reentry of space debris. There are over 120 eyewitness accounts on the American Meteor Society website (www.amsmeteors.org)

Lyrid Meteor Shower Peaks Tomorrow, April 22

Dust off the lawn chairs and get ready for the peak of the Lyrid meteor shower which will occur on the night of April 22.

“The Lyrids are really unpredictable,” Cooke said. “For the 2015 shower, I’m expecting 15 to 20 Lyrid meteors an hour. Peak rates should occur after 10:30 PM on April 22 your local time, for observers in the northern hemisphere. For observers in the southern hemisphere, Lyrid rates are not significant until after midnight your local time.”

Viewing tips for the Lyrids

No special equipment is needed to watch a meteor shower. Simply find a dark, open sky away from artificial lights. Lie down comfortably on a blanket or lawn chair, and look straight up.

A camera, provided by scientists at NASA’s Marshall Space Flight Center, will offer a live feed of the Lyrids beginning at 10:00 PM CDT.The camera is light-activated, and will switch on at nightfall. During daytime hours, the webcast will show recorded views of past meteor showers.

Watch the live feed here.

About the Lyrids

Lyrids are pieces of debris from the periodic Comet C/1861 G1 Thatcher and have been observed for more than 2,600 years. In mid-April of each year, Earth runs into the stream of debris from the comet, which causes the Lyrid meteor shower. You can tell if a meteor belongs to a particular shower by tracing back its path to see if it originates near a specific point in the sky, called the radiant. The constellation in which the radiant is located gives the shower its name, and in this case, Lyrids appear to come from a point in the constellation Lyra.

Second Fireball Occurs Over Northern Michigan

On Tuesday, Sept. 23, a second fireball occurred about 40 minutes after the fireball in Tennessee. The Michigan fireball is close to the edge of the camera because the meteor was at extreme range, over 200 miles away, for the camera.

The Michigan fireball was produced by a piece of a comet over 2 feet across, probably weighing around 40 pounds. It hit Earth’s atmosphere at a speed of 54,000 mph.

 

Alabama Fireball of August 2, 2014

We have completed our analyses and here’s what we know:

At 10:19 PM Central Daylight Time on August 2 (Saturday night), NASA meteor cameras detected a very bright fireball at an altitude of 57 miles above Hoodoo Road just east of the town of Beechgrove, TN. The meteoroid, which was about 15 inches in diameter and weighed close to 100 lbs, travelled just over 100 miles to the south south east at 47,000 miles per hour, breaking apart in a brilliant flash of light above the Alabama town of Henagar. The cameras continued to track a large fragment until it disappeared 18 miles above Gaylesville, located near Lake Weiss close to the Georgia state line. At last sight, the fragment was still traveling at 11,000 miles per hour. Based on the meteor’s speed, final altitude, and weak doppler radar signatures, it is believed that this fireball produced small meteorites on the ground somewhere between Borden Springs, AL and Lake Weiss.

The meteoroid’s orbit has its farthest point between the orbits of Mars and Jupiter, and is inclined to that of the Earth (which explains its southerly direction).

Check out the video!

The NASA Meteoroid Environment Office would like to hear from those in the area around Alabama’s Lake Weiss who may have heard sonic booms or like sounds around 10:20 PM Saturday night. Please contact Dr. Bill Cooke at william.j.cooke@nasa.gov if you have reports of such.

Sunday Night Fireball

On Sunday evening, a bright fireball was reported by visual observers in Tennessee. Occurring about 7:22 PM Central, the meteor was detected by 4 of our All Sky cameras – those in Huntsville; Chickamauga, GA; Cartersville, GA; and Dahlonega, GA. The fireball was picked up at an altitude of 55 miles moving east of south at 52,000 miles per hour; it burned up at an altitude of 27 miles just south of Anniston, AL. This was not a Taurid, as the orbit indicates it is a fragment from a Jupiter family comet, which have an aphelion (furthest distance from the Sun) out near Jupiter. This particular piece of interplanetary debris was between 2-3 inches in diameter and weighed about 5 ounces.

Southern California Lit Up By Fireball

The fireball over southern California last night at 7:49 PM PST was a North Taurid.  Brighter than the Full Moon, it was caused by a piece of Comet Encke about 2 feet in diameter hitting the atmosphere at 56,000 mph. Information about the fireball was provided by NASA’s Meteoroid Environment Office (MEO) and is the NASA organization responsible for meteoroid environments pertaining to spacecraft engineering and operations. The MEO leads NASA technical work on the meteoroid environment and coordinates the existing meteoroid expertise at NASA centers.

NASA All Sky Fireball Network Cameras Catch Perseids

The annual Perseid meteor shower peaked on Aug. 12 and 13, 2013, filling the sky with streaks of light caused by the meteoroids burning up in Earth’s atmosphere. Big meteor showers like the Perseids, are caused when Earth travels through a region of space filled with debris shed by a comet. The Perseids have been observed for at least 2,000 years and are the small fragments from comet Swift-Tuttle. These bits of ice and dust wander in space for centuries, finally burning up in the Earth’s atmosphere to create one of the best meteor showers of the year.

This Perseid fireball meteor was observed in the skies over Chickamauga, Ga., on Aug. 11, 2013, at 2:14:49 a.m. EDT. It was also recorded by four other cameras in the NASA All Sky Fireball Network. Image Credit: NASA/MSFC/MEO

Perseids Already Lighting Up The Night

Here is a video of a bright Perseid seen by our all-sky camera located at PARI (NC) in the early morning hours of July 30. Several Perseids have already been detected and they are not set to peak for over a week! The nights of August 11-12 and 12-13 will be the best time to observe, but check out fireballs.ndc.nasa.gov regularly to see how many have already been detected by our all-sky cameras!

 

Eta Aquarids Caught on Camera

 

Same meteor — same location — two different meteor cameras! The video shows the same meteor (an Eta Aquarid!) from one of our all-sky cameras and from our wide-field camera (~20×15 degree FOV) both located at Marshall Space Flight Center in Huntsville.

First Observations of the 2013 Eta Aquarids

Despite interference from the moon and clouds (and rising sun!), this morning we snagged our first observations of the 2013 Eta Aquarids.  Here’s an image of one from the all sky camera in Tullahoma, Tennessee.  The Eta Aquarids peak in the pre-dawn hours on May 6 and are material from Halley’s comet.  They zoom around the solar system at speeds near 148,000 mph.  The one seen here burned up completely in our atmosphere over Nunnelly, Tennessee at a height of 58.7 miles above the ground.
