Lesson 4.3 - Sunrise and Sunset Data for Different Latitudes

Directions: Record your group’s assigned location and its latitude and longitude. Record the seasonal sunrise and sunset times for that location in Table 1. Record the compass direction (NE, E, SE, S, SW, W, NW, N) from which the Sun rises and sets. Record the time of day at which solar noon occurs and record the Sun’s angle of separation at solar noon.
