On Earth, it is not possible to observe the Sun and the Moon together in the sky simultaneously from the same location. The reason for this is that the Sun and the Moon are generally on opposite sides of the sky relative to an observer on Earth.
During the daytime, when the Sun is visible, the Moon is usually not visible or is very difficult to see because it is overwhelmed by the Sun's brightness. The Moon is most commonly observed during the night when the Sun is below the horizon, and the Moon reflects sunlight to illuminate the night sky.
There are, however, certain rare celestial events where it is possible to see both the Sun and the Moon together, but they are not observed from a single location on Earth. For example, during a solar eclipse, the Moon passes between the Earth and the Sun, blocking the Sun's light and casting a shadow on Earth. In this case, observers within the path of totality can witness the Sun's corona around the Moon. However, this phenomenon is limited to specific regions along the eclipse path, and special precautions should be taken to protect your eyes when observing such events.
In general, it's important to remember that directly observing the Sun without proper eye protection can cause severe eye damage, so it is essential to take appropriate precautions and use safe viewing methods if you're interested in observing solar or lunar events.
