Did you mean to write 0.2' instead of .02'?
2 one hundredths of an arc minute in 4 seconds in time seems too fast.
If its really .02', Alex should be jumping for joy as he only missed the occultation by 1.2 arcseconds.

My Lunar4 program says Aldebaran is .02′ inside the Moon's limb at that time. It puts the occultation 4 seconds earlier. http://home.earthlink.net/~s543t-24dst/lunar3/
