What are the odds that:
- Someone walking homeward happens to look at the crescent moon around 8:15 pm.
- The planet Venus hangs very close, about two and a half moon diameters below.
- A camera is handy.
- The batteries are dead, but 3 spare batteries are miraculously available. With 3 new cells and 1 almost dead cell, the camera sputters to life. Pictures are feverishly snapped between 8:20 and 8:40 pm.
- Upon googling, it is found that the time of closest approach for viewers in the San Francisco Bay Area was 8:16 pm on May 19.
