Images of a region of sky at moderately high Galactic latitude (l=88.3{deg}, b=+34.9{deg}) were obtained on 2003 December 9-11. The survey consists of a shallow observation of 2.5x2{deg}^2^ centered at 17:18 +59:30 (main survey) and a deeper observation of 1{deg}x0.5{deg} centered at 17:17 +59:45 (verification survey). Issues with the reduction of the 24{mu}m MIPS data are discussed and solutions to attenuate instrumental effects are proposed and applied to the data. Approximately 17000 sources are extracted with a signal-to-noise ratio (S/N) greater than 5. The photometry of the point sources is evaluated through point-spread function (PSF) fitting using an empirical PSF derived from the data. Aperture corrections and the absolute calibration have been checked using stars in the field. Astrometric and photometric errors depend on the S/N of the source varying between 0.35"-1" and 5%-15%, respectively, for sources detected at 20-5{sigma}. The fluxes of the 123 extended sources have been estimated through aperture photometry. The extended sources cover less than 0.3% of the total area of the survey. Based on simulations, the main and verification surveys are 50% complete at 0.3 and 0.15mJy, respectively. Counterparts have been searched for in optical and radio catalogs.2006AJ....131.2859Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/131/2859CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/424/371 : 1.4GHz First Look Survey (FLS) (Morganti+, 2004)J/AJ/131/250 : Spitzer 70 and 160um observations in xFLS (Frayer+, 2006)J/MNRAS/376/1251 : 610MHz observations of Spitzer XFLS (Garn+, 2007)J/AJ/125/2411 : SIRTF First-Look Survey (Condon+, 2003)J/AJ/128/1 : First Look Survey: NOAO R-band Mosaic (Fadda+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/131/2859https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/131/2859http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/131/2859https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/131/2859https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/131/2859http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/131/2859GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/131/2859/table2 (Extended sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/131/2859/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/131/2859/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/131/2859/table2?GETtext/xml+votable180.050000true257.2114333360.195586110.005555555555555556Cone search capability for table J/AJ/131/2859/table5 (The 24{mu}m point source catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/131/2859/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/131/2859/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/131/2859/table5?GETtext/xml+votable180.050000true261.4222666760.04840.005555555555555556Cone search capability for table J/AJ/131/2859/table4 (Stars used for absolute calibration)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/131/2859/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/131/2859/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/131/2859/table4?GETtext/xml+votable180.050000true257.4928833358.648888890.0055555555555555565/2547 2553 6/10183 10187 10194 10200 10202 102093.036429446233786e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/131/2859?format=asciiOpticalInfrareddefaultJ/AJ/131/2859/table2Extended sourcesrecnoRecord number assigned by the VizieR team.
