Seventy-four years ago, Japan conducted a surprise attack, a carrier raid, on our naval base at Pearl Harbor, Hawaii, on the southern side of the island of O’hau. The National Geographic has a good timeline of the attack.
The attack began an hour after sunrise, when the sun was 13 degrees above the southeastern horizon, and ended approximately two hours later. Here’s a chart of the sun’s azimuth and altitude at Pearl on the day that still lives in infamy.
