Hi Bill,
The analysis gave the meteor an apparent magnitude of -1.5, as seen from my location. A meteor’s absolute magnitude is its estimated magnitude had it been in the observer’s / camera’s zenith at an altitude of 100 km. This meteor could easily have appeared brighter from your station.
It can be challenging to record meteors with a DSLR. Lens effective aperture and ISO setting are big factors. I have an example of a bright Perseid that was spectacular on my video camera but a much more feeble streak on my DSLR image.
Clear skies,
Alex.
