In this letter we present the first accurate analytical nutation series, de
duced from the Hamiltonian theory by the authors. They provide the highest
accuracy ever obtained by any analytical nutation series, since the deviati
on in CEP (celestial ephemeris pole) offsets with respect to that of the IE
RS Conventions 1996 is kept below 1 mas in the time domain, in spite of sti
ll lacking ocanic corrections.
