Online ephemeris question
Posted: Tue Dec 13, 2022 8:31 pm
by Martin Gansten
Solar Fire (which I use out of habit), and no doubt other commercial astrology software, offers the option of creating highly customized ephemerides – such as, for instance, displaying the longitude, latitude, right ascension and declination of the moon at 1-minute intervals over a day or part of a day.
That may sound eccentric, but is actually very useful for certain Placidean techniques that I teach as part of my Primary Directions Diploma Course. But these days, not all students own commercial software, which leads me to ask: does anyone here know of (preferably free) online resources that offer the same flexibility in producing ephemerides, e.g. in PDF format?

Hello Martin
Astrodienst Swiss Ephemeris - "
Test Output" online tool allows it:
Here is the quick link for today ephemeris (Moon - longitude, latitude, right ascension and declination - minute by minute):
https://www.astro.com/cgi/swetest.cgi?b ... arg=-ut+-g
(your students can bookmark that link - and just replace the current date 14.12.2022 by any other date)

And here is the link to Astrodienst's form generator with some explanation:

That's wonderfully helpful, Petr! Thanks so much!

Hi Martin - Jean Cremer's Extended Ephemeris in Planetdance does most of this. The only missing variable is right ascension. I will ask him if he could include this in the listing (should be easy) and then your students might wish to download this software.
Best wishes. Ed
Planetdance Update
Posted: Wed Dec 14, 2022 7:16 pm
by astralwanderer
Hi Martin - Jean has updated Planetdance so that the Extended Ephemeris module (under the Time menu) now lists right ascension, longitude etc. The ephemeris can be run for a minimum step of one minute, so a student could run the ephemeris for a number of hours by choosing, say, 600 steps = 10 hours, or more, depending on the speed of their computer. The actual listing is quite speedy so this shouldn't be too much of a problem.
The software can be downloaded from
www.jcremers.com.
All the best. Ed

Hello,
I published an update for this:
December 14
+ Added Right Ascension to Time - Extended Ephemeris.
It will also export to csv.

Habit or not, it won't hurt to take a look at planetdance Martin, you might be surprised., there are comprehensive classic, medieval, etc. sections

petr9 and jean
do these programs work on ubuntu? i have probably asked this question before, but when i upgraded to ubuntu 22, i lost solar fire... i have it on the laptop, but i am looking for a program that i can run on ubuntu.... i am also especially interested in using the 90 degree wheel, and dasa data... thanks for any input on this...

There is also this option for generating the ephemeris data:
http://www.true-node.com/eph1/
It find it has an easier to use interface than the Astrodienst (check boxes rather than command line switches, actual planet names), but also based on the Swiss Ephemeris.
Cheers!
