We observed 30 lunar occultations (LO) in the near infrared of sources in the Taurus and Ophiuchus star-forming regions (SFRs) during three runs from September 1991 to January 1993. Twenty-six of the sources were proper young stellar objects (YSOs), the remaining four were field stars (or at least suspected to be). Our observations have led to the discovery of the following new binary systems: HK Tau/G2, IW Tau, HP Tau and HP Tau/G3 in Taurus, and GSS 35 and VSSG 14 in Ophiuchus. In the case of the known binary Haro 6-10 (Leinert & Haas 1989), our observation shows the presence of extended emission around the main component, while nothing can be said about the circumbinary disk suggested by Menard et al. (1993). Additionally, FY Tau should be considered a suspected binary, and we find the field star VSS 35 to be double. We discuss the implications of these new findings: at least in the Taurus SFR, where most of our events were observed, the currently emerging view that most-if not all-stars begin their life as members of binary or multiple systems (Ghez et al. 1993, Leinert et al. 1993, Simon et al. 1994) appears strengthened; a statistical discussion of all LO observations obtained so far in the Taurus and Ophiuchus SFRs will be given by Simon et al. (1994).
