Literally 5 seconds after the previous photo was taken.
I really should have been shooting at about 1/60 of a second here - all the structure and brilliant pinks in these bands have been washed out by the super fast motion at a 10/25 sec. It was kind of the theme of the night, always getting caught off-gaurd.
I had to underexpose a bit to avoid totally blowing out and oversaturating the aurora. This was probably the brightest band I have ever seen.
