This HII region, entwined with the star cluster NGC 7380, contains 4000 solar masses of gas and is ionised by the eclipsing binary star DH Cephei (O6+O6). It is associated with a molecular cloud containing an additional 6-15 thousand solar masses of gas, and the star cluster NGC 7382, which are all part of the Cep OB1 association.
