The dark nebula Barnard 203 or Lynds 1448 is located about one degree southwest of NGC 1333 in the Perseus molecular cloud, at a distance of about 800 light-years. Three infrared sources were observed in this region by IRAS, called IRS 1, IRS 2 and IRS 3.[2]

The region also contains multiple Herbig-Haro objects, including HH 193–197, which are driven by the protostars in this region.[3]
