Comparison with earlier Wide Field Planetary Camera 2 images going back as much as 8yr has allowed determination of tangential velocities (proper motions) down to about 10km/s for a variety of sources. Multiple outflow systems are found associated with individual proplyds in the ionized portion of the nebula (HH 518, HH 624, possibly HH 507). The Orion-S complex of radio and infrared sources is the source of multiple outflows. A new outflow system (HH 625) has been identified as coming from the blueshifted portion of the imbedded high velocity CO flow coming from the Orion-S region, this object having CO, H2, and low ionization optical components. The low velocity CO outflow originating from or near FIR 4 is the likely source of HH 530. A new imbedded source is inferred from this optical data to lie in Orion-S. This optical outflow source (OOS) clearly feeds the systems HH 269 and HH 529, which lie along a straight line. There is evidence that this is also the source for HH 528, HH 202, and HH 203/204, all of which are blueshifted (except possibly HH 528 whose radial velocity is unknown). There is no strong radio, infrared, or X-ray source within the positional ellipse of the OOS.2003AJ....125..277Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/125/277CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/104 : General Catalogue of Herbig-Haro Objects (Reipurth+, 1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/125/277https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/125/277http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/125/277https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/125/277https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/125/277http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/125/277GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/125/277/table1 (Proper Motions in the Central Orion Nebula)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/125/277/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/125/277/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/125/277/table1?GETtext/xml+votable180.050000true83.79375-5.4044440.0055555555555555566/21439https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/125/277?format=asciiOpticaldefaultJ/AJ/125/277/table1Proper Motions in the Central Orion NebularecnoRecord number assigned by the VizieR team.
