We measure the transverse baryon acoustic oscillations (BAO) signal in thelocal Universe using a sample of blue galaxies from the Sloan Digital SkySurvey (SDSS) survey as a cosmological tracer. The method is weakly dependenton a cosmological model and is suitable for 2D analyses in thin redshift binsto investigate the SDSS data in the interval $z {\in} [0.105, 0.115]$. Wedetect the transverse BAO signal ${\theta}_{BAO} = 19.8^{\deg} {\pm}1.05^{\deg}$ at $z_{eff} = 0.11$, with a statistical significance of $2.2{\sigma}$. Additionally, we perform tests that confirm the robustness of thisangular BAO signature. Supported by a large set of log-normal simulations, ourerror analyses include statistical and systematic contributions. In addition,considering the sound horizon scale calculated by the Planck Collaboration,$r_{s}^{Planck}$, and the ${\theta}_{BAO}$ value obtained here, we obtain ameasurement of the angular diameter distance $D_{A}(0.11) = 258.31 {\pm} 13.71\,Mpc/h$. Moreover, combining this ${\theta}_{BAO}$ measurement at low redshiftwith other BAO angular scale data reported in the literature, we performstatistical analyses for the cosmological parameters of some Lambda cold darkmatter (${\Lambda}$CDM) type models.
