In this paper we present near infrared (NIR) imaging data of the host galaxyof the broad absorption line quasar (BALQ) at z=2.169, serendipitously foundclose to 3C48. The data were obtained with the ESO-VLT camera ISAAC duringperiod 67. We find extended, rest-frame optical emission around the BALQ aftersubtracting a scaled stellar point spread function from the quasar nucleus inJ, H, and Ks. The extended rest-frame optical emission can be interpreted as anapproximately 2 Gyr old stellar population composing the host galaxy of theBALQ or a stellar population of similar age associated with an intermediate(z=1.667) absorption system spectroscopically identified by Canalizo & Stockton(1998) simultaneously. The rest-frame-UV emission on the other hand isdominated by a young, 500 Myr old stellar population. The UV/optical colorsresemble a mixture of the two populations, of which the young one accounts forabout 80%. Assuming that the residual emission is located at the BALQ redshift,we find that the host galaxy has a resolved flux of about 10% of the BALQ flux.The physical scale is quite compact, typical for radio quiet QSOs or Lymanbreak galaxies at these redshifts, indicating that the systems are still in theprocess of forming.Comment: 14 pages, referee style, 6 figures, 4 tables, accepted for  publication in A&
