Small objects:  Today's Daily Orbit Update MPEC has observations of small asteroid 2003 WJ98 from Desert Moon Observatory yesterday morning, but nothing further for celebrity rocks 2003 XJ7 and 2003 XV and other small objects in recent view. The Minor Planet Center's Last Observation page is showing that the newest of these, 2003 XH10, was caught by Powell Observatory this morning.

EKB news:  Astronomy.com has an article today, "The Neptune effect." For links related to this story, see A/CC's report.

Robot telescopes:  Astronomy.com has an article from yesterday, "United Kingdom's magic bus," about the Faulkes Telescopes Project. See A/CC's News brief ("Readings") for links behind this article and more info on the project.

GhanaWeb reports today that a Japanese consortium has installed a telescope in Ghana that will make nighttime observing available to Japanese students over the Internet during their local day. See A/CC's August 28th report for more about this, and for links to other information about remotely-operated and robotic educational telescopes.

Risk monitoring 8 Dec.

The Monday Daily Orbit Update MPEC (DOU) has observations of 2003 XL from Desert Moon Observatory yesterday morning in New Mexico and Great Shefford Observatory last night in England. Only JPL had listed this object, which is roughly estimated at 1.6 km. (1 mile) wide, and these were the first positions reported since its discovery MPEC four days ago. Today it was removed from the JPL Current Impact Risks page.

The DOU also reports observations of 2003 XM from Sormano Observatory in Italy Friday night and from Desert Moon yesterday morning. Today NEODyS and JPL both cut their counts of impact solutions and slightly lowered their risk estimates for this half-kilometer size object.

The Minor Planet Center's Last Observation page is showing that 2003 WG was caught this morning by Linz Observatory in Austria.
