Abstract. We report on the detection at Mt.Abu of H+ 3 molecular ion emissions in the near infrared spectra of the northern auroral zone of Jupiter. These H+3 transitions are of rotational-vibrational origin and are due to the dynamics of Jovian auroral ionosphere located mainly at high Jovian latitudes, which confirms their magnetospheric origin. The main overtone transition at 2.093 m and several other transitions including that of H2 have been detected. Details are presented.
