IC 2162 = Sharpless 255 is the brighter and eastern of two very similar HII regions. Listed by Stewart Sharpless in his catalogue of HII regions (the western is No. 257), these two are among the brightest (though not the largest) HII regions in a large area of star formation in the northern reaches of Orion.

Barnard apparently found the object visually (we need to look at his observing records to be sure). He sent the observation directly to Dreyer and did not publish it before the IC2 appeared. His position is about 10 seconds of time too large, but his description "vF, pL, R, * 10 inv p" is appropriate. The star "involved" is the central star -- the brightest portion of the nebula is the eastern side.
