Abstract
The talk presents an update of the bottom quark mass determination from QCD moment sum rules for the Y system by the authors [1]. Employing the <(MS)o ver bar> scheme, we find m(b)(m(b)) = 4.19 +/- 0.06 GeV. The differences to our previous analysis will be discussed and we comment on the determinatio n of the pole mass for the bottom quark.
