The BAT observes 88% of the sky each day with a detection sensitivity of 5.3 mCrab for a full-day observation and a time resolution as fine as 64s. The three main purposes of the monitor are (1) the discovery of new transient X-ray sources, (2) the detection of outbursts or other changes in the flux of known X-ray sources, and (3) the generation of light curves of more than 900 sources spanning over eight years. The primary interface for the BAT transient monitor is a public Web site. Between 2005 February 12 and 2013 April 30, 245 sources have been detected in the monitor, 146 of them persistent and 99 detected only in outburst. Among these sources, 17 were previously unknown and were discovered in the transient monitor. In this paper, we discuss the methodology and the data processing and filtering for the BAT transient monitor and review its sensitivity and exposure. We provide a summary of the source detections and classify them according to the variability of their light curves. Finally, we review all new BAT monitor discoveries. For the new sources that are previously unpublished, we present basic data analysis and interpretations.2013ApJS..209...14Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/209/14CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/207/19 : Hard X-ray from Swift-BAT 2004-2010 (Baumgartner+, 2013)J/ApJS/201/34 : Swift-INTEGRAL X-ray (SIX) survey (Bottacini+, 2012)J/A+A/545/A101 : Spectra of 29 Swift/BAT optical counterparts (Parisi+, 2012)J/ApJ/740/87 : Chandra observations of radio transients (Croft+, 2011)J/ApJ/739/57 : Ultra hard X-ray AGNs in the Swift/BAT survey (Koss+, 2011)J/ApJS/186/378 : Hard X-ray survey from Swift-BAT 2004-2006 (Tueller+, 2010)J/A+A/524/A64 : The 54-month Palermo BAT-survey catalogue (Cusumano+, 2010)J/A+A/520/A47 : Blazars in the Swift-BAT hard X-ray sky (Maselli+, 2010)J/A+A/510/A48 : Palermo Swift-BAT Hard X-ray Catalogue (Cusumano+, 2010)J/ApJ/673/96 : BAT X-ray Survey - III (Ajello+, 2008)J/A+A/462/1081 : BVRIJHK light curves of 4U 0115+63/V635 Cas (Reig+, 2007)J/ApJ/643/356 : Transient X-ray sources in M31 (Williams+, 2006)J/A+A/407/1039 : X-ray power spectra of Cygnus X-1 (Pottschmidt+, 2003)J/PAZh/26/27 : Cyg X-1 (V1357) variability in 1995-1996 (Karitskaya+, 2000)http://swift.gsfc.nasa.gov/results/transients : Swift/BAT Hard X-rayhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/209/14https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/209/14http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/209/14https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/209/14https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/209/14http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/209/14GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/209/14/table3 (Sources detected in the BAT transient monitor)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/209/14/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/209/14/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/209/14/table3?GETtext/xml+votable180.050000true7.20459.2890.005555555555555556Cone search capability for table J/ApJS/209/14/table6 (Localizations of Swift/BAT discovered transients)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/209/14/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/209/14/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/209/14/table6?GETtext/xml+votable180.050000true78.367875-65.788583330.005555555555555556Swift6/845 1196 1263 1405 1694 1701 1796 2564 3030 3035 3041 3160 3309 3728 3729 4439 5423 7642 7869 8922 9512 9612 10166 10912 12336 12405 13875 14251 14285 14410 14452 14632 14664 14677 14692 14744 14858 15090 15367 15433 15476 16301 17075 18524 19283 20099 20618 21450 21690 23323 23652 24120 24185 24451 24842 25690 25907 26148 26292 26393 27767 28690 28705 28744 28751 28798 28805 28808 28817 28825 28826 28827 28828 28830 28831 28835 28848 28849 28853 28860 28875 28877 28879 28880 28885 28896 28898 28899 28900 28901 28903 28916 28922 28924 28925 28950 28970 28971 29078 29100 29113 29114 29115 29180 29185 29204 29221 29234 29306 29314 29416 29463 29504 29514 29523 29691 29706 29795 29870 29885 29923 30138 30239 30244 30256 30257 30258 30262 30271 30299 30362 30400 30417 30428 30433 30439 30506 30598 30618 30619 30622 30719 30753 30993 32549 33095 33113 33136 33287 33298 34242 34428 36930 37363 37475 37732 37906 37921 37925 38028 38268 38653 38704 39235 39238 39246 39937 41279 41303 41399 41404 41522 41530 41586 41596 41647 41662 41679 41681 41697 41758 41797 41802 41810 41813 41814 41823 42016 42018 42140 42159 42163 42169 42196 42207 42210 42211 42214 42215 42224 42228 42229 42314 42315 42370 42378 42384 42387 42389 42393 42396 42417 42446 42451 42461 42464 42467 42468 42547 43020 43233 43262 43677 43806 43877 44660 44908 45735 46399 46987 47805 47866 48034 49042https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/209/14?format=asciiX-raydefaultJ/ApJS/209/14/table3Sources detected in the BAT transient monitorSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
