- Longest possible total eclipse is only 7.5 minutes. Average is only 2-3 minutes.
- Shadow sweeps across Earth @ 1000 mph!
- Birds will go to roost in a total eclipse. The temperature noticeably drops.
- Totally predictable (even in ancient times, e.g., the Saros Cycle,
eclipse pattern repeats every 6585.3 days or 18 years, 11 1/3 days).
