(meteorobs) black meteors

[Eric Bynum]

Dear wonderful meteorobs.org people:
        A nebulosity (per dictionary definition) is a cloudy, diffuse 
phenomenon.  Black meteors may not necessarily be nebulous meteors.   Since 
the background against which the purported "black meteor" is observed can 
never be entirely black, the existence of something even "darker" than the 
night sky (even in areas free of light pollution) makes sense to me.
