The absolute solar oxygen abundance,ɛ &sun; = 8.80± 0.06, has been determined from various oxygen abundance indicators in different solar atlases, and a new method is proposed to test collision rate coefficientsfor the NLTE model of OI.Using effective temperatures derived from Balmer lines, oxygen abundances from O triplets in 83 solar-type stars within the solar neighborhood spanning a metallicity range of [Fe/H] = -2.3 ... +0.4 have been determined.NLTE effects are not negligible, especially in warm stars(Teff ≥ 5800) with [Fe/H] ≥ -0.5.
