Solar orbit statistics and your agenda

Solar orbit statistics and your agenda

[Eric S Fraga]

Time for a very geeky post...

Recently, on the remind (diary tool I used to use) mailing list,
somebody posted a script for converting solar data (perihelion, equinox,
...) to remind input.  I've done the same for org so if you're
interested in that kind of information and want your agenda to show
this, here is the script:

#+begin_src shell :results output raw
  tmpfile=$(mktemp /tmp/date.XXXXXX)
  for year in $(seq 2018 2068)
  do
      links http://aa.usno.navy.mil/seasons?year=${year} -dump | \
          grep -E 'helion|quinox|olstice' > ${tmpfile}
      while read -r line
      do
          item=$(echo $line | awk '{print $1}')
          date="$(echo $line | awk '{print $5 " " $4 " " $3}') ${year}"
          isodate=$(date --date="${date}" +"%Y-%m-%d %H:%M")
          echo "** <${isodate}> $item"
      done < ${tmpfile}
  done
  rm ${tmpfile}
#+end_src

Notes:

1. this is for Linux and assumes bash as the shell.
2. the default is UTC (and this is where I wish org supported time
   zones...).
3. I believe the URL for the US Naval Observatory in the code above
   accepts "?tz=N?dst=M" for different time zones (some index N) and
   daylight savings options (M set to 0 or 1 maybe?) but I haven't
   played with these options.
4. you will need to install "links".

Enjoy but use at own risk etc. ;-)

Eric:

This is extremely useful.   I found some documentation on the site, re the
API.  I am way over my head here, but I need (for one) data on Lunar
Declination over, say, a year, but really month-by-month.  Is there a "for
Dummies" to get this data off of this server?  A cookbook?  Can I do
something like this?

grep -E 'oon&&eclin' >${tmpfile}

?

Thank you again.

Glad you liked it.  Strangely enough, they seem to have changed the
format of output (now sending json) so the script no longer works.

What is the link for the API information?  With that, I may be able to
help answer your question about getting lunar declination data off the
server.

I will search for the API page later.  It seems to me that the site was not
behaving normally today, and I struggled to find that page.  I may have
printed it!

Meanwhile, I was able to use a part of the script to get sun information,
but nothing for the moon?   I wanted to get series of declinations through
the month.  Attached is the test script I used, and it worked even when I
could not locate the pages any other way!

The same thing for :erigee" did not work.

I did not see anything related to lunar data.  Maybe elsewhere on the site?

Hello, Eric:

Since I don't need to automate anything or directly pipe the data into any
other processes, I have taken a leap of faith and used the JPL Horizons
Ephemeris Web interface to generate an ephemeris for the Moon's (they say
"Luna"---nice!) declination.  This I can edit wtih Emacs to get the data I
need.

Had I time enough, it would be cool to interface that in a more interesting
way.

Thank you for the advice.

Alan

Eric:

I was able to access the API docs (requiring, with my Firefox, to accept a
security exception.)

https://aa.usno.navy.mil/data/docs/api.php

I have to move on.  I have found that XEphem's Moon declination output is
excellent, so I only have to convert the time format.

Thank you for your help,

Alan

Very useful.  Thanks.  With wget, I had to add --no-check-certificate to get anywhere.  Now just need to write some code to interpret the JSON output!
