Students completed this diagram of the paths for the sun for San Luis Obispo, CA on an in-class activity ("lecture-tutorial"). However, this diagram was not provided on the quiz.
In June, the sun will rise on the horizon between northeast and east, and takes 14 hours to set on the horizon between west and northwest. The sun will rise on the horizon due east during March or September. So the soonest that the sun will rise on the horizon due east after June would be September, three months later.
