Hi Ellen,
here are the instructions for the web page this is from a past post....
I too don’t have solar fire but there in an on line ephermals at
http://www.megadelfi.com/~jonathan/ When you go to the site click on Ephermeris (it opens and directs you to another page)
2. the top line fill in the planets that you want the nodes for
3. put in the birth day info
4. when it says “Number in line” change it to 1 or you will get 31 days of the nodal placement
5. click on show north node and show south node
6. then click on get ephemeris
it does not bring up a chart, but you can get the ephemeris and plot them in yourself…
hope this helps…
