Leonids (Meteor Shower) & International Space Station Transit
Taken during 2001 Leonids. I was set up close to the Royal Astronomical Society of Canada (RASC; Ottawa Chapter) club gathering (star party) and overheard the warning of the upcoming Space Station transit in Cassiopeia. I quickly spun my camera around, opened the shutter, and it just appeared. It's the streak in the photo. You can also see a Leonid, thrown in for good measure. Film scan.
