Is it possible to view the sun and moon in the sky at the same time?
Can you explain what you are asking. Everyone sees the moon and sun in the sky at the same time. It happens after sunrise for part of the month, and before sunset for part of the month. You say you know this, but then you imply it's only for an eclipse.
