On September 16, at 8:22:25 PM local time, NASA meteor cameras in north Georgia and western North Carolina detected a bright fireball over middle Alabama. First seen at an altitude of 45 miles above Paul M. Grist State Park, near Selma, Alabama, the 6 inch diameter chunk of asteroid moved east at a speed of 38,000 miles per hour before burning up some 28 miles above northern Elmore County. At its most intense, the meteor was even brighter than a crescent Moon.
This composite image shows the meteors detected by the NASA All Sky Fireball Network station here in Huntsville, Alabama this morning. The majority of the meteors are Perseids, but a handful belong to the Northern Delta Aquariid, Southern Delta Aquariid, Alpha Capricornid, and Southern Iota Aquariid meteor showers that are also active.
This Perseid meteor was observed by the NASA Wide-field Meteor Camera Network in the skies over Huntsville, Alabama on the morning of August 12.
Rhiannon Blaauw, of NASA’s Meteoroid Environment Office — located at NASA’s Marshall Space Flight Center in Huntsville, Alabama — shares some tips and strategies to best view a meteor shower.
Each spring as Earth passes through the debris trail from Halley’s Comet (1P/Halley), the cosmic bits burn up in our atmosphere and result in the annual Eta Aquarid meteor shower. This year the peak will occur on May 6 about 9 AM EDT with meteor rates of about 30 meteors per hour near peak. Best viewing is just before dawn on May 6. Eta Aquarids zoom around the solar system at speeds near 148,000 mph. Unfortunately for meteor shower observing enthusiasts the moon will seriously hampered viewing of the ETAs this year. reducing the peak rate to under 20 meteors per hour.
The Eta Aquarids are pieces of debris from Halley’s Comet, which is a well-known comet that is viewable from Earth approximately every 76 years. Also known as 1P/Halley, this comet was last viewable from Earth in 1986 and won’t be visible again until the middle of 2061. The annual Eta Aquarid meteor shower gets its name because the radiant — or direction of origin — of the meteors appears to come from the constellation Aquarius.

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.

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.
A fireball occurred over southern Wyoming/northern Colorado at 6:01 AM Mountain Daylight Time. The available eyewitness and video information indicates that the meteor moved from East to West at about 45,000 miles per hour and weighed a few pounds (2 to 4 pounds are the preliminary estimates). The fireball belongs to a class of meteors called Earthgrazers, which hit the Earth’s atmosphere at a very shallow angle. They can travel a considerable distance before getting low enough to completely burn up; the eyewitnesses state that this fireball lasted longer than 10 seconds, which matches grazer durations. No meteorites are expected to have been produced by this event – it was too small and too high to drop fragments on the ground.
The numerous reports are typical of fireballs occurring during morning or evening work commute, and are not indicative of the relative brightness of the meteor.
