Search for HH objects and emission stars in star formation regions. IV. New Herbig-Haro flows and objects associated with cometary nebulae As part of a project to search for new Herbig-Haro (HH) objects in starformation regions, observations are reported on the neighborhoods offive cometary nebulae: MacC H12, MacC sH15, GM 1-14, RNO 33, and Pars17. We have been able to identify 9 previously unknown HH objects inthose regions. Almost all of these objects belong to directed flowswhose sources are, with high probability, the central stars of thesenebulae. In the cases of MacC H12 and GM 1-14, the outflows have adistinct bipolar structure. The sources of the outflows are located on aJ-H/H-K diagram in order to classify them.
