NATIONAL METEOR WATCH DAY – June 30

  National Meteor Watch Day - June 30

NATIONAL METEOR WATCH DAY

National Meteor Watch Day is observed every year on June 30th.  On this day, which is also known as National Meteor Day,  people across the country search the skies hoping to find meteors or “shooting stars” streaking across their view.

Daily there are millions of meteors that occur in the Earth’s atmosphere.

“A meteor or “shooting star” is the visible streak of light from a meteoroid or micro-meteoroid, heated and glowing from entering the Earth’s atmosphere, as it sheds glowing material in its wake.” (Wikipedia)

The majority of the meteoroids that cause meteors are only the size of a pebble.

Meteors sometimes occur in showers.

Meteors are usually observed at night and are visible when they are about 34 to 70 miles above the Earth and they usually disintegrated at about 31 to 51 miles above.  Their glow time is normally about a second.

A very small percent of meteoroids hit the Earth’s atmosphere and then skip back into space. 

The chemical composition and the speed of the meteoroid will cause different hues to the light.  Possible colors and elements producing them include:

  • Orange/yellow (sodium)
  • Yellow (iron)
  • Blue/green (copper)
  • Purple (potassium)
  • Red (silicate)

A list of meteor shower dates as well a a guide to successful watching can be found on the EarthSky website.
