Why meteors can look green
Bright meteors can excite atmospheric oxygen and vaporized material, producing green or blue-green emission. Camera sensors, exposure, white balance and the observer dark adaptation can change the recorded hue.
Other green lights exist
Aircraft navigation lights, lasers, aurora and optical effects can all introduce green. The key question is still what the light did: streaked for two seconds, blinked repeatedly, remained stationary or spread across the sky.
A fireball record is different evidence
If a CNEOS event lies near the sighting in time and broad geography, that is stronger evidence than color. Even then, Sky Event Radar describes a possible match rather than certifying that the observer saw the same event.
Report the observation
Write bright green streak, about three seconds, west to east rather than green meteor. Keeping the raw observation separate makes later matching more reliable.
Verification sources
Use NASA/JPL CNEOS, CelesTrak, ADSB.lol, NOAA SWPC and Launch Library 2 according to their coverage and time window. Sky Event Radar keeps missing evidence explicit.
