dc.description.abstract	We report the GMRT detection of H I absorption in the high_ redshlft red quasar 30 190 at a redshift of 1.1946. The most interesting result is that the peak of the H I absorption is blueshifted by I'W 250 kms-1 with respect to the optical emission lines. The H I absorption profile indicates the presence of multiple components and the peak: absorption is at 647.728 MHz. The FWHM of this absorption feature is 185 ±7 kms-1and the peak optical depth is 0.012. The corresponding atomic hydrogen column density is 3.98 x 1020 (T8/100K) cm-2•	en
