Abstract
We present a new photometric analysis of the Local Group Dwarf Irregular Galaxy NGC 6822 based on archival Hubble Space Telescope Advanced Camera for Surveys images. The data correspond to three fields covering the south-east region of the galaxy; for each field F475W and F814W HST bands are available. For each field an accurate color magnitude diagram (F814W, F475W-F814W) has been obtained. Preliminary hints on the galaxy star formation history are presented based on the comparison with isochrones from "A Bag of Stellar Tracks and Isochrones" (BaSTI) database.
