Notes:  2006 SV19 was discovered by the Catalina Sky Survey on 19 Sept. 2006 and announced on the 20th, which is when JPL posted it a risk with the earliest, highly preliminary, impact solution less than five years away. NEODyS posted it on the 22nd and the next day raised it to Torino Scale 1 for an impact solution in 2029. This signaled a low level of concern that was reduced back to TS-0 only a day later, when both risk monitors eliminated all impact solutions before the year 2062, and was eliminated altogether on Sept. 28th.

JPL:  Orbit Viewer     NEODyS:  object home page [backup] & observations [backup]

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.

Notes:  2006 RZ was discovered on the evening of 4 Sept. 2006 by "H." (Hilma and/or Helmut?) Michels at Herrenberg Observatory in Germany, who confirmed it the next night. This was correlated with observation from LINEAR early on Sept. 1st and the discovery was announced on 6th, which is when JPL posted it with impact solutions. NEODyS posted it on the 7th and removed it on Sept. 12th, and JPL removed its last solution on Sept. 15th.

This is at least the year's second amateur discovery of a near-Earth asteroid, and is certainly the second to be posted for a time as an impact risk.

On Sept. 6th it was reported that Sergio Foglia, Giuseppe Forti, and Maura Tombelli found 2006 QY110 in the archives from NEAT's Haleakala telescope from 23 July and 13 Aug. 2003, and the next day NEODyS removed its last impact solution for this object. In a follow-up MPEC of 19 April 2007, the Minor Planet Center reported that these 2003 precovery observations were "being removed from the MPC files" due to concerns over how that data fit with the new orbit calculation resulting from the recovery of this object by Spacewatch and the Mt. Lemmon Survey.

That radar data was posted on Sept. 12th by JPL and NEODyS. 2006 QV89 was calculated to go out of view for most NEO observers around Sept. 12th and was last reported on the 8th by Great Shefford Observatory.
