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.
A bright meteor occurred over West Virginia last night at 9:27 EDT. It was seen across Ohio, Pennsylvania, Virginia, North Carolina, and Maryland! NASA’s Pennsylvania and Ohio all sky cameras caught it near the edge of the field-of-view, but what also saw it was an EarthCam located on the Washington Monument!
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.
Enjoy a summer evening of sky watching as the annual Perseid meteor shower peaks on the night of August 12 through the morning of August 13. Join meteor experts from NASA’s Marshall Space Flight Center for live Ustream commentary during the shower. Perseid meteor rates can get as high as 100 per hour, with many fireballs visible in the night sky
How to View the Perseid meteor shower
The best opportunity to see the Perseid meteor shower is during the dark, pre-dawn hours of August 13. The Perseidss streak across the sky from many directions. For optimal viewing, find an open skyline, where you can view the horizon without obstructions, such as buildings or trees. Try to view the Perseids as far away from artificial lights as possible. The darker the sky, the better viewing experience you can have. Lie on the ground and look straight up. Remember, your eyes can take up to 30 minutes to adjust to the darkness, so allow plenty of time for your eyes to adjust.
About the Perseids
The Perseids have been observed for at least 2,000 years and are associated with the comet Swift-Tuttle, which orbits the sun once every 133 years. Every August, the Earth passes through a cloud of the comet’s debris. This debris field consists of bits of ice and dust — most over 1,000 years old — and burns up in Earth’s atmosphere to create one of the best meteor showers of the year. The Perseids can be seen all over the sky, but the best viewing opportunities will be across the northern hemisphere. Those with sharp eyes will see that the meteors radiate from the direction of the constellation Perseus.
NASA Ustream: Observe the Perseid Meteor Shower
On Aug. 12, NASA’s Marshall Space Flight Center in Huntsville, Alabama, will host a live Ustream broadcast about the Perseid meteor shower. The event will highlight the science behind the Perseids, as well as NASA research related to meteors and comets. The broadcast will air 9 p.m. CDT Aug. 12, to 1 a.m. CDT Aug. 13 on the following Ustream channel: http://www.ustream.tv/channel/nasa-msfc
Special guests will include meteor experts Dr. Bill Cooke, Danielle Moser and Rhiannon Blaauw, all of NASA’s Micrometeoroid Office, located at Marshall. They will provide on-air commentary, as well as answer questions online, using Marshall social media accounts. Also scheduled to join the broadcast, via telephone, are experts from NASA’s Johnson Space Center, in Houston; NASA’s Goddard Space Flight Center in Greenbelt, Maryland; the American Meteor Society; the SETI Institute in Mountain View, California; and others.
There are two methods to join the online conversation during the broadcast. NASA followers can tweet questions to “@NASA_Marshall” using the hashtag “#askNASA.” Followers may also post questions on the Marshall Facebook account, replying to the 9 p.m. Aug. 12 Perseid “Q&A” post at: https://www.facebook.com/nasamarshallcenter
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.
To read more about fireballs, go to NASA All Sky Fireball Network.
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.
