(meteorobs) (Meteorobs) comment on being green

[drobnock]

It has been suggested that the green meteor trails are from the
ionization of oxygen or the excitation of the oxygen atoms. So is it
proper to state -- for those interested in green trails - that  green
meteor trails are green  at 100 km up to about 150 km. Red oxygen meteor
trails  are 150 km upwards to 250 km and more rarely to 600 km plus?

Is the composition of the meteor and the colour of the trail
attribured to the mineral composition? Per flame test of minerals. For
example  a red meteor may be  -  Red because Both lithium and strontium
produce a red flame and the strontium flame is brighter red.  or
Orange/yellow Calcium burns with an orange flame. Sodium burns bright
yellow. or Green A number of elements generate flames in the green
spectrum. Barium and molybdenum produce yellowish-green flames. Boron
creates a bright green colour. Thallium burns pure green. Phosphorus and
zinc burn bluish green. or Blue Selenium, indium and arsenic burn blue.
