The colour-colour and colour-magnitude diagrams of the objects are discussed. Many of the objects under consideration, starlike from the ground, are probably dense young star clusters (super star clusters, SSC). Ages spreading over ~4 to ~150Myr are estimated for most of these objects. Sakai and Madore (2001ApJ...555..280S) found enhanced star formation ~30-125Myr ago also in the halo of this galaxy; thus, high star forming activity has occurred within the entire galaxy (centre and halo) since ~130..150Myr. Having ended in the outer regions about 30Myr ago, it is going on near the centre with full vigour.2004AN....325..307Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AN/325/307CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AN/325/307https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AN/325/307http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AN/325/307https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AN/325/307https://vizier.iucaa.in/viz-bin/votable?-source=J/AN/325/307http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AN/325/307GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AN/325/307/table2 (UBVIc photometry of bright starlike objects in NGC 3077)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AN/325/307/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AN/325/307/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AN/325/307/table2?GETtext/xml+votable180.050000true150.762266168.67548860.0055555555555555566/7604https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AN/325/307?format=asciiOpticalInfrareddefaultJ/AN/325/307/table2UBVIc photometry of bright starlike objects in NGC 3077recnoRecord number assigned by the VizieR team.
