It is interesting that there is some (albeit small) variability in the  
values from different sources. Here are results (just RA) from XEphem  
(Version 3.7.5-RC6 January 30, 2010; a Delta T value of 68.39s used):

Equinox J2000
topocentric: 5h 19m 36.17s
geocentric:  5h 19m 36.41s

Equinox of Date
topocentric: 5h 20m 25.33s
geocentric:  5h 20m 25.10s
