Description
We present the results of the search for candidate Planetary Nebulae
interacting with the interstellar medium (PN-ISM) in the framework of
the INT Photometric Hα Survey (IPHAS) and located in the right
ascension range 18-20 h. The detection capability of this new Northern
survey, in terms of depth and imaging resolution, has allowed us to
overcome the detection problem generally associated to the low surface
brightness inherent to PNe-ISM. We discuss the detection of 21 IPHAS
PN-ISM candidates. Thus, different stages of interaction were observed,
implying various morphologies i.e. from the unaffected to totally
disrupted shapes. The majority of the sources belong to the so-called
WZO2 stage which main characteristic is a brightening of the nebula's
shell in the direction of motion. The new findings are encouraging as
they would be a first step into the reduction of the scarcity of
observational data and they would provide new insights into the physical
processes occurring in the rather evolved PNe.
