FIREBALLS

 

NASA selected the Hands-On Science Center in Tullahoma to be the third site and their all sky net of cameras looking for meteors. They keep adding sites and now there are over 19. The cameras are about 15 inches high and HOSC’s camera is located on the roof of H Wing at UTSI.  This location was picked to minimize light pollution.
 

 

These cameras record meteors as bright or brighter than Venus which are at least the size of a golf ball.  If at least two sites record a meteor track within a 150-mile radius of both sites a NASA computer will triangulate and analyzes the data to show: the object’s path around the sun, its velocity and its track.  Although most visible meteors are the size of a grain of sand only a few make it to earth.
 

 

If you see a meteor, wait until after 8 A.M. the next day and

This site shows the network of cameras across the US and lists 
radarlive view showing dates where there were meteors to analyze.  

 

Pick for example 20180418        

 

 This April 19 in 2018.

 

Note the third site over is Tullahoma and it shows a meteor track at 09:25:54 UTC        

 

This is 9:25 54 sec A.M. also known as Greenwich time. Subtract 5 hours to get CDST or 6 hours to get CST.
