The directions to do this are here:
I just did the natal chart of someone who died.
When I tried to change the url, I found that it's after you do the chart, you append it, as follows.
The only real changes is the Universal Time change, instead of midnight you can calculate the new UT to say , 8:30PM, using
8.5 (use decimals)instead.
that way you can see the Sun, and Moon position at the exact time of the transit itself, instead of just the midnight UT of 00.00UT
