AAA says Gas Pump Prices Pushing Cheaper, Again

 

AAATampa, FL – On the week, the majority of states saw gas prices decrease minimally – by one to two cents or saw no change at the pump. Though low, the volatility was enough to drive the national average down a penny from last Monday to $2.17. Today’s average is two cents less than last month and 49 cents cheaper than a year ago.

“As we move into the second week of the August, it is pricing out to be the second cheapest start to the month in more than a decade,” said Jeanette Casselano, AAA spokesperson.

AAA reports Tennessee Gas Price Average Falls 3 Cents

 

AAANashville, TN – AAA says that gas prices, on average, dropped three cents across Tennessee over the last week. 

The Tennessee Gas Price average  is now $1.89 which is five cents less than one month ago and nearly 50 cents less than one year ago. 

“As we move into the second week of the August, it is pricing out to be the second cheapest start to the month in more than a decade,” said Megan Cooper, spokesperson, AAA – The Auto Club Group.

NASA releases update on Hurricane Dorian

 

Devastating Category 5 Hurricane Dorian Makes a Direct Hit on Abacos Islands

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA reports that the eye of Category 5 Hurricane Dorian was directly over the Abacos Islands as of the National Hurricane Center’s (NHC) 3:00pm CDT advisory and is now heading towards Grand Bahama Island.

The hurricane is located about 185 miles (295 km) east of West Palm Beach, FL. Maximum sustained winds are 185 mph (295 km/h) with gusts over 200 mph.

Dorian is moving west at 7 mph. The central pressure is 911 Mb which continues to lower meaning the storm continues to intensify. This is the fifth Category 5 hurricane sustained in the last five years.

NASA Study reveals reasons for Sea Ice Changes at the Arctic, Antarctica

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Why has the sea ice cover surrounding Antarctica been increasing slightly, in sharp contrast to the drastic loss of sea ice occurring in the Arctic Ocean? A new NASA-led study finds the geology of Antarctica and the Southern Ocean are responsible.

A NASA/NOAA/university team led by Son Nghiem of NASA’s Jet Propulsion Laboratory, Pasadena, California, used satellite radar, sea surface temperature, land form and bathymetry (ocean depth) data to study the physical processes and properties affecting Antarctic sea ice.

NASA’s Solar Dynamics Observatory (SDO) witnesses Solar Flare emitted by our Sun Saturday, October 20th

 

Written by Karen C. Fox
NASA Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – The sun emitted a significant solar flare, peaking at 2:14pm EDT on October 20th, 2012. This flare is classified as an M9 flare. M-class flares are the weakest flares that can still cause some space weather effects near Earth.

Since flares are rated on a scale from 1 to 10, an M9 is a particularly strong M class flare, but still ten times weaker than the most powerful flares, which are labeled X-class.

NASA's Solar Dynamics Observatory (SDO) captured this image of an M9-class flare on Oct 20th, 2012 at 2:14pm EDT. This image shows light at a wavelength of 131 Angstroms, which corresponds to material at 10 million Kelvin, and is a good wavelength for observing flares. This wavelength is typically colorized as teal, as shown here. (Credit: NASA/SDO)
