The Extended 3.3 µm Emission Feature in the Orion’s Cloud
AROME, a balloon borne experiment has been built in order to detect the 3.3 µm emission feature in extended sources (description of AROME is given in M. Giard et al., these proceedings). Particular areas outside the galactic disk have been mapped. The figure presents Orion survey map of 3.3 µm emission in AROME narrow band, and points out an extended emission around Ori A and Ori B. The AROME field of view (0.5°) allows to measure the extended emission around the excited regions.
