## [22.08] Survey of Planetary Nebulae in the Southern Galactic Bulge

We are presenting preliminary results of our survey of Planetary Nebul\ae~ in the Southern Galactic Bulge. This is a uniform narrowband imaging survey in $H_{\alpha}$ of the region of galactic longitude l = $\pm 20 \deg$ and galactic latitude b = $-5 \deg$ to $-10 \deg$. We will measure radial velocities of our newly- found PNe, and have already measured velocities of the previously known PNe in a more extended region to provide a kinematic sample of uniform quality. The combined sample of velocities will be used for a dynamical study of the galactic bulge. After two seasons of observation, we have imaged 94\% of our target area. We have analysed the data from the first season: in the 227 fields analysed (which translate to 47\% of the coverage), we have found 53 PNe of which 25 are already known and 28 are newly discovered - we have thus approximately doubled the number of known PNe in the regions surveyed so far.
