Abstract:

We have combined the observational data of the AAO/UKST and Marseille H$\alpha $ surveys to extract preliminary new results about ionised structures of our Galaxy. This includes the detection of a new large bubble located in the far part of the Carina arm.

Keywords: surveys: H$\alpha $ -- Galaxy: structure and kinematics -- ISM: HII regions -- ISM: individual ( G297.506-0.765, G297.655-0.977, RCW48, G298.187-0.782, SNRG296.1-0.7)
