Notes:  2006 UA64 was discovered and confirmed solely by the Mt. Lemmon Survey (MLS) on 22-23 Oct. 2006 and announced on the 24th. NEODyS posted it as an impact risk on the 26th after additional observation on the 23rd from MLS was published, and removed it on Oct. 28th when the next observation became available.

With the removal of its impact solutions, NEODyS reported an orbit calculation on Oct. 28th (see today's) that had 2006 UA64 staying so far away from Earth that even the planet Mars comes closer. This is a good example of just how much further observation can affect early impact risk analysis for newly discovered objects.

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.

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.

Circulars:  MPEC 2006-O46

Notes:  2006 OT9 was discovered by NEAT with its Mt. Palomar telescope on 25 July 2006 and announced the next day. JPL posted it then as an impact risk and removed it on the 29th when the next observation was reported.

Circulars:  MPEC 2006-OS9

Notes:  2006 OS9 was found by LINEAR on 24 July 2006 and confirmed two days later by the Siding Spring Survey, which is when its discovery was announced. On July 28th JPL posted a single impact solution after further observing was reported, and this was removed on the 29th when the next observation was published.

Current assessment:  NO impact solutions

Circulars:  MPEC 2006-O22

Notes:  2006 OK was discovered on 22 July 2006 by the Siding Spring Survey and announced the same day ahead of this object passing through the Earth-Moon system the next day at about 0.7 lunar distance from Earth. JPL posted a single very low-rated impact solution on the 22nd, based on the original 5.42-hour observation arc, and removed it on the 23rd after the arc was extended by another 6.26 hours.

2006 OK3 was the first newly discovered object to become rated as a risk since 2006 MJ10 on June 23rd, and this episode was the first risk monitoring news since July 1st, when 2005 WY55 was reported and removed as a risk.
