Nothing. The sun cannot see, it has no organs of sight.
It is left
You only will see a rainbow if you're facing the opposite direction of the sun
When you see a half moon, the position of the Sun is either directly to the right or left of the Moon as viewed from Earth. This is because a half moon occurs when the Sun, Earth, and Moon form a 90-degree angle, with the Sun illuminating half of the side facing Earth.
The moon itself does not 'shine' like the sun does, so it requires the position of the sun to hit it, in a way that makes it look illuminated, being visible to us. Since the Earth moves every day around the sun, the position of the sun hitting the moon changes how much we can/can't see it. :)
The sun rises in the east due to the stationary position of the sun, and the relative position of the Earth. If the Earth's axis is considered up, then, when looking down at the North Pole, the Earth is spinning counter-clockwise.
90 degrees (approximately) from the position of the moon, in the direction of the lighted side.
The sun is a large, hot sphere of gas, which condensed out of an even larger but cooler cloud of gas some five billion years ago. The position of the sun in the sky is what we see from our perspective here on Earth, but the sun is in outer space, some 93 million miles away from Earth.
The phases of the moon are caused by the relative positions of the sun, the moon and the observer. It is possible to see phases of the moon in space depending on your position relative to the sun and the moon.
The Moon appears to wax and wane as seen from Earth due to its changing position relative to the Sun. When the Moon is between the Earth and the Sun, we see the illuminated side (waxing). When the Earth is between the Moon and the Sun, we see the shadowed side (waning).
As "Pink Floyd" said " when the sun is eclipsed by the moon." Your viewing position has to be right to see it happen.
If you are standing in the penumbra during a solar eclipse, you would see a portion of the sun's surface, but not the entire disk. The penumbra is the outer region of a shadow where only a partial eclipse occurs, meaning that some sunlight is still visible. Depending on your exact position within the penumbra, you could see up to 99% of the sun, with a small section being obscured by the moon.
If Teresa looks out the window exactly one day later, she will see the sun rising in the same eastern position on the horizon. The sun rises in the east every day, so its position relative to her window will remain consistent. However, due to the Earth's rotation and tilt, the exact point on the horizon may shift slightly over the course of the year.
