We present infrared imaging and spectroscopic data of the complex massive star-forming region G10.47+0.03. The detection of seven mid-infrared (MIR) sources in our field combined with a sensitive Ks/ISAAC image allows to establish a very accurate astrometry, at the level of 0.3". Two MIR sources are found to be coincident with two ultracompact HII regions (UCHIIs) within our astrometric accuracy. Another MIR source lies very close to three other UCHII regions and to the hot molecular core (HMC)doi:10.1051/0004-6361:20035880 fatcat:eu2zut2bo5hjzpk2cczv5yztlq
