This is an update to my earlier post on this subject. You can download Celestia and see what happened on April 3 of 33 A.D. for yourself with this handy little celestia script. Just save the script to your desktop, launch Celestia, and click File, Open Script, and select the file you downloaded. It appears that this script needed some adjustments for the newest version of Celestia 1.6.0.
P.S. If anyone knows from the change logs, which revision it was in Celestia which caused this script to need adjustment, please let me know. Thanks.
