Below is a plot of the rough count of meteors captured on the three cameras (#1=blue, #2=purple, #3=white on the graph). The first exposures were started shortly after midnight (HST) and continued past 5AM with a gap at about 3AM when cameras ran out of film and were being reloaded. Exposures were roughly 7 minutes in length with about a minute between exposures to advance film, recheck polar alignment, and start new exposures. A total of 32, 27, and 26 meteors were captured by each camera, respectively.

The count was done by examining the negatives with a 4x loupe. This rough survey's absolute numbers don't have any real significance, but the increase in the count towards the end of the night matches the visual impression of a small peak right after midnight with a significant increase in activity as dawn approached. The last meteor was seen only 5 minutes before sunrise with only Venus still visible in the sky.
