On Friday, July 31, 2020, at 20:03:39 (UTC), The JPL Center for NEO Studies (CNEOS) removed the asteroid 2020 NK1 from Sentry: Earth Impact Monitoring Table.  2020 NK1 was posted to NASA JPL's Sentry and ESA's Risk List soon after its "discovery" by ATLAS-MLO, Mauna Loa. It was given  a Torino Scale rating of 1 Normal (Green Zone).  In the days that follow, observers from around the world submitted observations.  With this data, Arecibo Observatory was able to take radar observations, greatly lowering its orbital uncertainty, allowing the CNEOS to rule out any impacts for the for seeable future.
