The spectrum of fluorescent molecular hydrogen in the photodissociation region (PDR) in NGC 2023 is presented. 87 H2 lines have been measured from the bright H2 emission ridge 80 arcsec south of the illuminating star (HD 37903). Infrared images of the PDR taken with 1–0 S(1) and 2.1-μm continuum filters are presented. The infrared and far-red line fluxes provide column densities for 66 rovibrational states of the H2 molecule from vibrational levels within the range v=1–12.
