NEOWISE 2019 Data Release

The 2019 Data Release includes all data acquired during the fifth year of the NEOWISE Reactivation mission (Mainzer et al. 2014, ApJ, 792, 30), 13 December 2017 to 13 December 2018. These data are combined with the Year 1-4 NEOWISE data into a single archive that contains approximately 12.8 million sets of 3.4 and 4.6 micron images and a database of over 95 billion source detections extracted from those images.

NEOWISE scanned the sky nearly ten complete times during the first five years of survey operations, with approximately six months between survey passes. With twelve or more independent 3.4 and 4.6 micron exposures made on each point of the sky during each survey epoch, the NEOWISE archive is a time-domain resource for extracting multiple, independent thermal flux and position measurements of solar system small bodies, as well as background galactic and extragalactic sources.
