Ephemerides

[cfn]

Is there a way to get this for the moon? Trying to get the following data: rise/set ~approx. as it depends on lat/lon. We already have phases.
We're trying to work out a process to define a "clear night" as an alert on CFN. So this will depend on the following factors:

• Surface wind and Jetstream. (Seeing)
• Humidity, Precipitable Water and Temperature. (Transparency)
• Phase of the moon (Stray light and sky darkness)
• Cloud Coverage (Obviously)
• Fog (Early morning hours)

Any hep would be appreciated. Text file, CSV file or any tabular format that can be fed into a database will work. Thanks.

There several books that provide methods to compute the phase of the moon and moonrise/set times. Two are:

"Astronomical algorithms" by Jan Meeus.

"Practical astronomy with your calculator or spreadsheet", by Peter Duffett Smith

You have some coding to do to implement the maths, it is not a database problem you can solve with lookup tables or sql queries.

Trying to avoid more computation. We're already doing that for phases. At this stage just enquiring about tables availability. For sure there must be some pre calculated values for a given period of time ahead?
