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. |
