Presentation #118.08 in the session Large Surveys, Programs and Catalogs.
After the J-Band UKIRT Hemisphere Survey was completed and released (see Dye et al. 2018), the United States Naval Observatory (USNO) partnered with the University of Hawaii, Institute for Astronomy, the Cambridge Astronomical Survey Unit (CASU) and the Wide-Field Astronomy Unit (WFAU) at the Royal Observatory in Edinburgh to continue and complete the UKIRT Hemisphere Survey in multiple infrared bands for 12,700 sq. deg in the northern hemisphere. These surveys are completed with the Wide-Field Camera (WFCAM) on UKIRT and combine with the UKIRT Infrared Deep Sky Survey programs (UKIDSS) to give continuous northern hemisphere sky coverage from 0 to 60 degrees declination. K-band data collected between July 2017 and August 2020 is ready to be released to the public, and includes successful imaging for more than 90% of the survey area. H-band data collection is nearing completion and will be in the next data release. We have recently begun a second epoch of J-band coverage with simultaneous Y-band observations. This presentation will share the details of the surveys and characteristics of the data, focusing on the current K-band data release.
