The Sun will be in the easternmost position first thing in the morning.
In the morning, the Sun rises in the eastern part of the sky. This is due to the Earth's rotation from west to east which causes the Sun to appear on the eastern horizon as it moves from the nighttime side to the daytime side.
As a result, if we look towards the eastern sky at sunrise, you will see the Sun rising on the horizon marking the beginning of the day.
As the Earth continues its rotation throughout the day, the Sun will gradually move across the sky from east to west reaching its highest point in the southern sky around noon (in the Northern Hemisphere). After that, it will begin its descent towards the western horizon and ultimately setting in the west in the evening.
