We perform a study of S284 in order to outline the chain of events in this star-forming region. Description: We used four-band Spitzer/IRAC photometry as well as Hα imaging obtained with INT/WFC, during Cycle 4 (2005 March 28) under Programme ID 3340. Combining these data with the optical photometry obtained in the frame of CoRoTs preparation and the 2MASS catalog we analysed the properties and distribution of young stellar objects (YSOs) associated with point-like sources. We also studied the SEDs of regions of extended emission, complementing our dataset with IRAS and MSX data. File Summary:
