Current assessment: NO impact solutions
Diameter: 410 meters (JPL 22 Nov. 2006 estimate)

Circulars: MPECs 2006-S37 & 2006-T25
Notes: 2006 SU49 was discovered with the Spacewatch 0.9m telescope on 20 Sept. 2006 and was announced the next day, which is when JPL posted it as an impact risk. NEODyS posted it on the 22nd and both risk monitors raised it to Torino Scale 1 on the 27th. This signaled a low level of concern that was expected to be relieved by further observation.
Early on Oct. 4th the MPC published precovery observations of 2006 SU49 found by Rob Matson in the archives from NEAT's Mt. Palomar telescope from 21, 23, and 24 Oct. 2001. And, without credit coded to the archival sleuth(s) who did the work, the following DOU MPEC reported astrometry from NEAT/Palomar from 25 Oct. 2001 and from the Sloan Digital Sky Survey from 18 Nov. 2001.
NEODyS lowered 2006 SU49 to Torino Scale 0 on Oct. 4th and JPL removed all solutions. JPL relisted 2006 SU49 on Oct. 12th, removed it two days later, posted it on the 17th and removed it on the Oct. 21st, and put it back on its list again on Oct. 27th. NEODyS removed it on Nov. 17th and reposted it on the 21st. JPL again removed it on Nov. 23rd and NEODyS on Dec. 11th.
