This HII emission nebula contains filaments and lobes. The largest lobe (twisted double lobe) is thought to be interacting with the giant lambda Orionis molecular cloud nearby (blue star near center).

This is a very dim object that doesn't receive a lot of attention among astroimagers. Perhaps, because of all the other brighter more tempting goodies in Orion.
