cds-question@unistra.frsupernovaesurveysvariable-starsWe report on the results from the first six months of the Catalina Real-Time Transient Survey (CRTS). In order to search for optical transients (OTs) with timescales of minutes to years, the CRTS analyses data from the Catalina Sky Survey which repeatedly covers 26000 of square degrees on the sky. The CRTS provides a public stream of transients that are bright enough to be followed up using small telescopes. Since the beginning of the survey, all CRTS transients have been made available to astronomers around the world in real time using HTML tables, RSS feeds, and VOEvents. As part of our public outreach program, the detections are now also available in Keyhole Markup Language through Google Sky. The initial discoveries include over 350 unique OTs rising more than 2mag from past measurements. Sixty two of these are classified as supernovae (SNe), based on light curves, prior deep imaging and spectroscopic data. Seventy seven are due to cataclysmic variables (CVs; only 13 previously known), while an additional 100 transients were too infrequently sampled to distinguish between faint CVs and SNe. The remaining OTs include active galactic nucleus, blazars, high-proper-motions stars, highly variable stars (such as UV Ceti stars), and transients of an unknown nature.2009ApJ...696..870Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/696/870CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sn : Asiago Supernova Catalogue (Barbon et al., 1999-)V/123 : Catalog of Cataclysmic Variables (Downes+ 2001-2006)II/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)http://www.lpl.arizona.edu/css/ : Catalina Sky Survey (CSS) home pagehttp://voeventnet.caltech.edu/feeds/Catalina.shtml : Catalina Real-timehttp://nesssi.cacr.caltech.edu/catalina/Allns.html : CRTS Optical Transientshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/696/870https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/696/870http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/696/870https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/696/870https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/696/870http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/696/870GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/696/870/table3 (Blazar candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/696/870/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/696/870/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/696/870/table3?GETtext/xml+votable180.050000true182.46562518.168611110.005555555555555556Cone search capability for table J/ApJ/696/870/transients (Confirmed and candidate supernovae)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/696/870/transients?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/696/870/transients?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/696/870/transients?GETtext/xml+votable180.050000true224.055291718.85427780.0055555555555555566/70 373 465 489 569 689 994 1001 4123 4130 4145 4201 4206 4269 4438 4515 4695 4715 4785 4805 4857 4940 4951 5019 5089 5375 5394 6149 6235 6237 6439 6491 6719 6722 6757 8453 8494 8520 8549 8566 8610 8676 8788 8934 8974 8977 9072 9227 9402 9467 9577 9738 10288 10354 10763 10905 12590 13315 17326 17729 18378 18685 18852 19050 19073 19197 19309 19568 19871 21443 21823 21854 21862 22012 22367 22888 22947 23047 25079 25344 25423 25507 25616 25634 25742 25851 25872 25928 25934 26111 26207 26352 26499 26535 26739 27353 27402 27446 27482 27509 27665 27718 27751 27907 28066 28177 28259 28443 28498 28501 28616 30889 30947 31289 31317 31337 31355 31584 31586 31588 31618 31662 31664 31681 31690 31696 31980 32390 32415 32703 36789 36841 40811 40932 40959 44737 44792 450287.447298006782415e-19 1.4134638842407062e-18https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/696/870?format=asciidefaultJ/ApJ/696/870/table3Blazar candidatesrecnoRecord number assigned by the VizieR team.
