Thanks for that Geoffrey - I've used your method to try and replicate the prediction for Aldebaran on 29Oct2015 at the Orwell Observatory near me in Suffolk (oasi.org.uk). I get close with 215130 immersion 215900 emersion compared to their prediction of 214949 and 224824UT. It became easier when I remembered that I could get all this calculated for me on the usno site.
