  We investigate the validity of the Cosmological Principle by constraining the
cosmological parameters $H_0$ and $q_0$ through the celestial sphere. Our
analyses are performed in a low-redshift regime in order to follow a model
independent approach, using both Union2.1 and JLA Type Ia Supernovae (SNe)
compilations. We find that the preferred direction of the $H_0$ parameter in
the sky is consistent with the bulk flow motion of our local Universe in the
Union2.1 case, while the $q_0$ directional analysis seem to be anti-correlated
with the $H_0$ for both data sets. Furthermore, we test the consistency of
these results with Monte Carlo (MC) realisations, finding that the anisotropy
on both parameters are significant within $2-3\sigma$ confidence level, albeit
we find a significant correlation between the $H_0$ and $q_0$ mapping with the
angular distribution of SNe from the JLA compilation. Therefore, we conclude
that the detected anisotropies are either of local origin, or induced by the
non-uniform celestial coverage of the SNe data set.
