Abstract
We report on spectroscopic observations of QSO candidates in the 1.5 deg2 region centered at (OOh 53m, -28deg;03'). The candidates come from Clowes and Savage (CS sample), Campusano and Torres (CT sample) and a grism sample by ourselves. These observations which complement the spectroscopic data of CS, permitted the identification of all the QSOs in the CS and CT samples in the 1.5 deg2. The grism sample contributed with several additional QSOs. The total number of confirmed QSOs with B%<19 mag was eight. Three of them came from the CS sample alone, two from CT alone, one belonged to both samples, and the two remaining ones came from the grism sample. The implied surface density of QSOs is 5.3 . On the other hand, if the presently known number of QSOs is taken as the total number, we get that the CS sample and the CT sample contain 50% and 37% of them respectively. Finally, it is stressed that coordinated spectroscopic and photometric observations of the many QSO candidates in this area could supply a reasonably complete sample of QSOs.
