Notes: GGD 30 was first catalogued by Gyulbudaghian, Glushkov & Denisyuk in 1978 as a result of their search of the POSS plates for possible Herbig-Haro objects. The nature of GGD30 is still unclear. Both scenarios (Herbig-Haro object or reflection nebula) are possible. 

To the west of GGD30 one can find another faint nebula: HHG33.3+0.2, which was discovered by Capellaro et al in 1994. This nebula was identified as a Herbig-Haro object.
