Estimating Sun and Moon data
Last updated: June 6, 2019

  1. The sun.
  2. The moon.


The sun.

I found a detailed page with examples of how to compute solar positions and twilight times.



The moon.

Bob Miller (Michigan State) gave me a computer code in the early 2000s that tabulated moon poisition and phase. I used it to compute these data until ??? For now, here is an example of how I use it: 

 


[sco@mcs ~]$ utdatemoon.sh 
Usage: utdatemoon.sh 20190515  
arg1 - UT date (YYYYMMDD) 
arg2 - run in debug/verbose mode 

[sco@mcs ~]$ utdatemoon.sh 20190515 Y  
Debug flag is ON in utdatemoon.sh 
utdate = 20190515 
Enter any key to continue:
 81.500  12:19:00.90 +03:16:39.0   20190515      (illum,ra,dec,UTdate)
