cds-question@unistra.frgalaxy-clustersphotometryredshiftedOn 1999 May 26, one of the Sloan Digital Sky Survey (SDSS) fiber-fed spectrographs saw astronomical first light. This was followed by the first spectroscopic commissioning run during the dark period of 1999 June. We present here the first hour of extragalactic spectroscopy taken during these early commissioning stages: an observation of the Coma cluster of galaxies. Our data samples the southern part of this cluster, out to a radius of 15{deg} (1.8h^-1^Mpc, approximately to the virial radius) and thus fully covers the NGC 4839 group. We provide redshifts and spectral classifications for 196 Coma galaxies, of which 45 redshifts are new. For the 151 galaxies in common with the literature, we find excellent agreement between our redshift determinations and the published values, e.g., for the largest homogeneous sample of galaxies in common (63 galaxies observed by Colless & Dunn, 1996ApJ...458..435C) we find a mean offset of 3km/s and an rms scatter of only 24km/s.2001AJ....121.2331Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/121/2331CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/121/2331https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/121/2331http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/121/2331https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/121/2331https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/121/2331http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/121/2331GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/121/2331/table1 (Galaxy Redshifts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/121/2331/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/121/2331/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/121/2331/table1?GETtext/xml+votable180.050000true195.63666727.2952780.0055555555555555565/2594 6/10400 28127 28149https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/121/2331?format=asciiOpticaldefaultJ/AJ/121/2331/table1Galaxy RedshiftsrecnoRecord number assigned by the VizieR team.
