It depends on what you are expressing:
In the sentence "A beautiful sunny day dawned," there is no need for a comma, as it is a simple declarative sentence with a clear subject and verb. If additional information were added, such as in a compound sentence or a list, a comma might be necessary. However, in its current form, the sentence stands perfectly without punctuation.
To determine if tonight is a harvest moon, you'd need to check the lunar calendar for the current month. The harvest moon typically occurs in September, but the exact date varies each year. You can also look up the moon phase for tonight to see if it aligns with the harvest moon.
To determine if the moon is in the correct position tonight, you need to clarify what you mean by "correct position." The moon's position is constantly changing as it orbits the Earth, so it depends on what you are looking for, such as its phase, visibility, or position in the sky relative to certain landmarks.
