It's not that hard, if a bit tedious first try. Go to http://ssd.jpl.nasa.gov/horizons.cgi

Fill in as per the screenshot. The "change" links take you to subsidiary pages to fill in the values. I used the "60 days" option to get those start/stop/interval values. Click "Generate Ephemeris". If you allow the cookies it will remember what you said for next time.

You could use the "Table Settings" to restrict the output to just the first few columns.
