(meteorobs) Question

[Pavol Habuda]

Green line is 557.7nm forbidden (atomic) oxygen line. It is common for fast meteors for their afterglows. Total amount of light (integral intensity) in green line is few times of total intensity of actual meteor. Depending on various conditions (most important is height) you se either trace after meteor, or meteor of green color.

Subject: (meteorobs)  Question

There has been much discussion of late about "green" meteors and
fireballs. The phenomena of the green meteor historically became a rally
point for observes in the 1940's under Lincoln LaPaz.  And the "red
scare" of the 1950's. Now for the past year or so this colour green is
quite popular. Why? What is the significance for observers to view green
meteors? And can any one give an explanation about the composition of
the spectrum of a "green" meteor as opposed to the spectrum analysis of
a "bluish" fireball?
