(meteorobs) Strange Lightcurves

[Leo S.]

Hi Mark,

My guess is that they are just skimming the upper atmosphere, which is 
perhaps a bit uneven, like the surface of the sea where there are peaks 
and troughs, and where the brightness is diminished is where the meteor 
is passing through a trough ie. lack of atmosphere.
