On the basis of the highest resolution images so far obtained of the OB association LH 110, we show that the main exciting source of the HII region, Sk -71 51, is in fact a tight cluster of massive stars consisting of at least 6 components in an area ~4" wide. Spectroscopic observations allow us to revise the spectral type of the main component (#17) to O2V((f*))+OB, a very rare, hot type. We also classify several other stars associated with N 214C and study the extinction and excitation characteristics of the HII region. Moreover, we obtain BVR photometry and astrometry of 2365 stars and from the corresponding color-magnitude diagram study the stellar content of N 214C and the surrounding LH 110. Furthermore, we discover a striking compact blob of ionized gas in the outer northern part of N 214C. A spherical structure of ~5", in radius (~1.3pc), it is split into two lobes by absorbing dust running diametrically through its center. We discuss the possible nature of this object.2005A&A...436..117Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/436/117CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/436/117https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/436/117http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/436/117https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/436/117https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/436/117http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/436/117GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/436/117/n214 (Astrometry and BVR photometry of sources around LMC N214: numbers 1-48 concern the Sk-71 51 cluster ; other stars are numbered 49-2389)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/436/117/n214?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/436/117/n214?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/436/117/n214?GETtext/xml+votable180.050000true85.4200417-71.33480560.0055555555555555566/33090https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/436/117?format=asciiOpticalInfrareddefaultJ/A+A/436/117/n214Astrometry and BVR photometry of sources around LMC N214: numbers 1-48 concern the Sk-71 51 cluster ; other stars are numbered 49-2389recnoRecord number assigned by the VizieR team.
