Homework Help Overview

The discussion revolves around finding a website that can provide historical moon phases and their positions in the sky for a specific location, particularly focusing on data from the past 20-30 days. The original poster expresses a need for information on the moon's visibility and its elevation in the sky, along with optional weather conditions.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants suggest various websites that may provide moon phase data, including specific features like altitude and azimuth for the moon. There are inquiries about how to determine the moon's position in the sky on specific days, particularly regarding its elevation.

Discussion Status

Some participants have provided links to resources that may help with the moon phase data, while others are exploring the limitations of available information regarding the moon's elevation and visibility. There is an ongoing examination of how to interpret the data provided by these resources.

Contextual Notes

Participants note that the original poster has a deadline for their assignment, which adds urgency to the request for information. There is also mention of the need to interpret data carefully, as the moon's visibility can vary significantly based on its rise and set times.

I was wondering if there is a site that shows the moon phases for my specific location up to 20-30 days old. I need to know how much of the moon was showing that day, and idealy the part of sky it was in (high or low to horizon) and the weather conditions for that day (e.g. cloudy, clear, etc.).

The last two things are optional, basically I need a site that can at least give me the phase the moon was in each day from now going back a month or so. Please post any URL's that could help me just a little bit as I need this assignment finished by tommorow morning.

Try this site http://aa.usno.navy.mil/index.html under Data Services (their website use frames or I'd give you the link directly to Data Services).

The Moon phases will give you the Moon phases from 2000 to 2010.

Everyone sees the same Moon phases. For the info on the Az/El for the Moon at your particular location, scroll down to position of the Sun and Moon.

Further down, the Web based MICA can also be used for your specific location.

You can generate a calendar of moon phases for any date at:

Thanks for the help. So there is no way of knowing if it would have been "high" or "low" in the sky during each day?

For $5 you can purchase this program to give the elevation of the moon in the sky at any time at any latitude/longitude:

I assume you're talking about the maximum elevation (obviously the Moon is low when it first rises, gets higher, then is low in the sky again right before it sets).

The Naval Oservatory site I gave you gives you that info under Positions of the Sun and Moon - Altitude and Azimuth of the Sun or Moon During One Day. By altitude, they mean the same as elevation.

The table of moonrise and moonset times for the entire year can give you at least a feel for which days the Moon is higher than the other. The higher elevation the Moon reaches, the longer it's above the horizon. Subtracting the rise time from the set time (keep in mind you're subtracting hours and minutes) tells you how long the Moon was above the horizon. Notice, some days, the Moon rises, but doesn't set. If you look at the next day, the moon sets a few minutes after midnight, but doesn't rise until later in the day. In other words, it takes a little thought in order to interpret what they're giving you.
