Thank you, Omphalos. Very user-friendly for someone who is easily overwhelmed by visual stimuli.

From the online tool above, you can also search and generate the ephemeris for all minor planets
List here from The International Astronomical Union here

Also you have more options at eph3

Say you are married to Adams, you can see where Adams is in your chart or closer/similar names.

Thank you, Omphalos.

You are welcome. It is one of my favorite tools.
I just figured out last night (after looking through some of the documentation for the Swiss Ephemeris) that one can enter the nodes (as TrueNode and/or MeanNode) along with planet names and other objects. I had been trying to find that out for months and had somehow missed it before. Essential!

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...

Planetdance will work without a problem on Ubuntu. You will need to install Wine to handle the program. I use the interface Playonlinux, which will be downloaded from the Ubuntu repository. However this is simple and the installation is very like a Windows install.

Any questions just ask.

thanks! i will get back on this..i think wine is already installed, although when i did the update to ubuntu 22, it might have deleted the wine files which would explain why i don't have solar fire on this computer anymore.. cheers james

Astrolog is a free program for Windows, Unix, and Mac which can generate ephemeris tables of various types.

You can specify the object(s) to include, such as planets, asteroids, and stars, as well as less common things such as orbital apsis points, Arabic parts, and midpoints. You can also choose what to display about them, e.g. zodiac position longitude, latitude/declination, or more obscure variables such as the rate of change of distance from the observer. Astrolog's global settings will affect its ephemeris, so you can get an ephemeris in Right Ascension coordinates, of harmonic chart adjusted positions, export the ephemeris to text or HTML, and so on. For example, the following command line will display an ephemeris of "Snow White and the Seven Dwarfs" (i.e. of Pluto and the seven largest bodies beyond its orbit, which are Dwarf planets or Dwarf planet candidates) in coordinates relative to the solar system barycenter, over a period of 600 years at a step rate of 25 years:

Code: Select all

astrolog -qy 1500 =EY0 601 y25 =b0 -R0 Plu Eri Hau Mak Gon Qua Sed Orc =h =Yh

Astrolog's ephemeris can be displayed in text or graphics form. Its extensability allows one to do an ephemeris for less common variables, or even things not directly related to celestial bodies such as Delta-T offset over time. For example, you can customize a planet's "position" to be current Delta-T, which can then be graphed in Astrolog's ephemeris chart. The command line below will graph Delta-T in seconds between the years 1600 and 2100. If you do this, Astrolog's will accurately reproduce the graph seen at the top of the Wikipedia Delta-T article at: https://en.wikipedia.org/wiki/%CE%94T_%28timekeeping%29

Code: Select all

astrolog -qy 1600 =EY 500 =gp _g =Xe -YX7 899 -R0 Ear -~O "=x DeltaT"

Hi James, planetdance works fine on linux. Ed and i both have it running on linux mint XFCE.

Hi James - see below screenshots for your areas of interest. If there are other techniques you use let me know because PD probably does them!

Thanks. Ed

thanks.. i have mint on my thinkpad laptop and solar fire works on that, but i have gotten into the habit of using this mainframe computer which has ubuntu... the time seems right to adopt a different astro program.. i have been too reliant of my friends help in all of this..

thanks ed!

that is awesome... i spoke with my friend who helped set up solar fire on ubuntu for me.. i lost it with the ubuntu 22 update.. he was using wintricks... i tried setting up playonlinux without success so far... i might be in over my paygrade, but will try again..

james,
Many people prefer planetdance over solar fire, it's no shame.

lol! that may be true... i am not closed minded here on any of this... cheers james

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)

--

Since quite a while now, swestest supports simpler step size format, like -s60s for step size 60 seconds.

Code: Select all

-sN     timestep N days, default 1. This option is only meaningful
                when combined with option -n.
                If an 'y' is appended, the time step is in years instead of days, 
                for example -s10y for a time step of 10 years.
                If an 'mo' is appended, the time step is in months instead of days, 
                for example -s3mo for a time step of 3 months.
                If an 'm' is appended, the time step is in minutes instead of days, 
                for example -s15m for a time step of 15 minutes.
                If an 's' is appended, the time step is in seconds instead of days, 
                for example -s1s for a time step of 1 second.
