Scientific paper

Results of the lunar occultation of IRS 16 on 1986 September 11 are reported. Sixty percent of the observed flux in a 6arcsec.5 beam comes from four discrete sources. Three sources are unresolved pointlike objects (< 0arcsec.05) and are assumed to be individual stars. The fourth object is well resolved with a diameter of 0arcsec.3 (0.01 pc). By timing the lunar occultation, the authors have identified this 9th mag object with IRS 16 NE. This blue object near the dynamical center may be a very compact cluster of stars and thus the true center of the Galaxy.
