There was very little light pollution in the sky at this location and was sat in a dark conservatory with only low lighting and lots of glass - this did not look like a small, fast shooting star high up in the sky - looked like a fireball with a fiery trail and from my perspective looked large in the sky - akin to the types of fireballs seen in a film. Very dramatic and was still visible with a second glance a few seconds after first seeing it.
