Fireball spotted northwest of Chicago, February 6, 1:25 AM CST

There was a very bright green fireball seen by hundreds of eyewitnesses surrounding Lake Michigan early this morning at 1:25:13 AM Central Time (February 6, 2017). The reports from these individuals and the video information from dash cameras and other cameras in the region indicate that the meteor originated 62 miles above West Bend, Wisconsin and moved northeast at about 38,000 miles per hour. It disrupted about 21 miles above Lake Michigan, approximately 9 miles east of the town of Newton. The explosive force of this disruption was recorded on an infrasound station in Manitoba, some 600 miles away – these data put the lower limit energy of the event at about 10 tons of TNT, which means we are dealing with a meteoroid – orbit indicates an asteroidal fragment – weighing at least 600 pounds and 2 feet in diameter. Doppler weather radar picked up fragments (meteorites) falling into Lake Michigan near the end point of the trajectory.

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.

Ask an Astronomer About the Shortest Lunar Eclipse of the Century on April 4

On Saturday morning, April 4, 2015 not long before sunrise, the bright full moon over North America should turn a lovely shade of celestial red during a total lunar eclipse. Join NASA astronomer Mitzi Adams as she takes questions via Twitter @NASA_Marshall. For Twitter questions, use the hashtag #eclipse2015. The question and answer via Twitter will begin at 6 a.m. EDT and continue through the end of the eclipse (approximately 8:00 a.m. EDT on April 4).

The lunar eclipse will be visible from all parts of the United States.  Eastern North America and western South America can see beginning stages of the partial umbral eclipse low in the west before sunrise April 4, whereas middle Asia (India, western China, mid-Asian Russia) can view the ending stages of the partial umbral eclipse low in the east after sunset April 4. Greenland, Iceland, Europe, Africa and the Middle East won’t see this eclipse at all. A world map of eclipse visibility is available here. The total eclipse will last only five minutes. You can find more information  here.

Fireball over Jacksonville, Florida on Feb. 21

A fireball west of Jacksonville, FL on Saturday, Feb. 21st  at 22:59:45 PM EST was detected by two all sky cameras, located in Melbourne, belonging to the Sky Sentinel Network.

The American Meteor Society has a write-up on this fireball at http://www.amsmeteors.org/2015/02/florida-fireball-with-boom/. There were over a hundred eyewitness reports, and the trajectory determined from these agrees fairly well with a crude triangulation performed using the Sky Sentinel videos. These videos and eyewitness reports indicate that the fireball started just east of Lake City and moved NE at about 40,000 miles per hour, burning up about 30 miles west of Jacksonville. The apparent brightness of the meteor permits a crude estimate of about a foot for the object’s diameter, with a weight around 100 pounds.

NASA places a high priority on tracking asteroids and protecting our home planet from them. In fact, the U.S. has the most robust and productive survey and detection program for discovering near-Earth objects (NEOs). NASA’s NEO Program at NASA Headquarters, Washington, manages and funds the search, study and monitoring of asteroids and comets whose orbits periodically bring them close to Earth. NASA is also pursuing an Asteroid Redirect Mission (ARM) which will identify, redirect and send astronauts to explore an asteroid. Among its many exploration goals, the mission could demonstrate basic planetary defense techniques for asteroid deflection.

Marshall Scientist to Observe Asteroid 2004 BL86

On Monday evening, January 26 from 10 p.m. to midnight CST Marshall scientists will observe the large Asteroid 2004 BL86 as it passes by Earth. The public is welcome to follow their observations via the Marshall Ustream feed

The asteroid will safely pass about three times the distance of Earth to the moon, or approximately 745,000 miles (1.2 million kilometers) from Earth. Scientists have been tracking the path of the asteroid for 11 years and know its orbit well. Asteroid 2004 BL86 will not approach Earth this close again for at least 200 years.

This is a rare opportunity for observation. Hope you will join us as we observe the flyby.

Go here for more information about Asteroid 2004 BL86.

LIve Chat and Ustream! 2014 Perseid Meteor Shower

The annual Perseid meteor shower will peak in the skies over Earth on the night of Aug. 12-13. Despite a bright moon, there should still be a good show from this prolific shower. Projected peak rates are 30-40 meteors/hour. Much of the world can see Perseids any time after full dark, with peak viewing projected early on the morning of Aug. 13 (3-4 a.m., your local time).

Dr. Bill Cooke, Rhiannon Blaauw and Danielle Moser of the NASA Meteoroid Environment Office will take your Perseid questions via live web chat. The chat module will appear on this page on Aug. 12 at 11 p.m. EDT (Aug. 13, 3:00 UTC). A Ustream view of the skies over Marshall Space Flight Center will be embedded on this page on Aug. 12 at 9:30 p.m. EDT (Aug. 13, 1:30 UTC).
