Object data of GGD30 |
|||
| Object type: | reflection nebula or Herbig-Haro object | ||
| Size: | |||
| Magnitude: | |||
| Constellation: | Aql | ||
| Distance: | |||
| 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. |
