Remember to start Stellarium with the “fallback mode” option if you need to for your computer.2. Check to make sure that Terre Haute is still your default location. If not, reset that.3. Change your surroundings in another menu, if you like.II. Set Viewing OptionsThe time is set to daylight on purpose. I doubt that the atmosphere will interfere with finding the Sun. Set the time to 12:01 pm on October 23.III. Get the Data1. Find the Sun (not much of a challenge).2.
