New-found: Saturday the 13th was a lucky day for LINEAR in New Mexico, discovering two kilometer-size objects in the morning that were confirmed and announced this morning — 2003 XE11 (MPEC 2003-X54) and 2003 XF11 (MPEC 2003-X55). The larger of the two, XF11 at about 1.2 km. (0.74 mile) wide, is categorized by the Minor Planet Center as potentially hazardous.

The Sunday Daily Orbit Update MPEC has a 2003 XM observation triplet from Great Shefford Observatory this morning in England. And today NEODyS pared its 2003 XM risk assessment down to just two low-rated impact solutions. Update: At 9:45pm Sunday in Pasadena, JPL had not updated its 2003 XM assessment with yesterday and today's new data.
The Minor Planet Center's Last Observation page is is showing that Jornada Observatory in New Mexico caught 2003 WW26 this morning.
