Word eating time! I'd checked surrounding exposures for other images of the glow, but just noted that a "satellite" on the previous exp (a field immediately to the north) wasn't ID'd. The southern edge of that trail, just as it crossed into the field had a red smudge for a couple of degrees, so it/was/ a meteor train! On reflection, the more condensed trail on the 2nd exposure of the pair was just an elongated and enhanced section of the glow in the first exposure. It would have originated from part of the meteor that was outside the field on the prior exposure containing the meteor. Sorry folks.
