AI Thread Summary
The discussion focuses on determining the time the new moon reaches its apex, which is defined as the highest point in its transit across the night sky. It is noted that during a new moon, the moon is close to the sun and will transit the meridian around local noon. A helpful resource is provided, allowing users to input their date and location to find local sunset, sunrise, and transit times for both the sun and moon. The concept of transit is clarified as the moment when the moon is at its highest altitude in its path across the sky. The exchange emphasizes the importance of understanding local time variations when calculating these events.

Greetings physics wizzes!

I am trying to find out what time the new moon reaches it's apex tonight. This is probably the most elementary task but I'm fairly clueless when it comes to this stuff.
Any help would be greatly appreciated, Thanks.

What's an "apex?"

I'm under the impression that this is the highest point of the moon's transit across the night sky.
 
If it's a new moon then it will be close to the sun and will transit the meridian around noon (local time). Of course, the exact time of the new moon doesn't coincide with everyone's local noon time.

Here's a link to a site which let's you enter the date and your location and will return local sunset/sunrise/transit and moonset/rise/transit.

Transit in this case refers to when the object in question transits the meridian.

I should add that when an object transits the meridian (the line drawn across the sky from north to south), it is at its highest altitude in its path across the sky.
 
Thanks Jimmy,
Okay, so that makes sense.. that being the new moon it would be very near the sun so when the sun is at it's highest it would serve to figure that ...sheesh. That should have occurred to me.
Thanks for the link.. very handy.
 
You're welcome. :smile:
