I observed the eclipse from Washington DC area yesterday. I have a few questions. from the eclipse map and youtube clips ppl uploaded, the eclipse starts in Oregon and sweep across states. questions: 1. I know earth rotate around itself from west towards east every 24 hrs, is this the main reason ppl on the west coast see the eclipse first? 2. which direction moon rotate around earth? I assume also west towards east? 3. it took around 1 hour and half for the totality max region sweep through continental US. 1720UTC ~ 1845UTC. is this mainly corresponding to earth's rotational speed or moon's?
