Paul:
This continuum generally appears in the spectrum of some bright meteors
recorded on film. Why it doesn't appear in all of them is not yet resolved.
Video systems record fainter spectra than film cameras can, so I think Jiri
is surprised that it is present in some of these fainter spectra. Why this
occurs at all is not understood at the present time. Meteor spectra are
very complex and much still has to be learned about them.
