Cover: Yesterday's "cover" showed a nearby 400-meter asteroid imaged with a 4.2m telescope and adaptive optics (AO). The images at left show what the venerable 100" (2.7m) Hooker Telescope at Mt. Wilson can do with its new AO system, capturing some details of Main Belt asteroid 3 Juno [link|alt], which is about 240 km. (150 miles) wide. A Harvard-Smithsonion news release last August described this as "the equivalent of a dime seen at a distance of 7 miles" (see more info and also Juno meteorite news yesterday).

Risk monitoring - part 1/1 Major News for 27 Jan. 2004 back top next  
Risk monitoring 27 Jan.

The Tuesday Daily Orbit Update MPEC (DOU) has observations of 2004 BV1 from the 2.5m Isaac Newton Telescope at La Palma in the Canary Islands from Sunday night, and today NEODyS removed its last impact solution for this object. JPL cut its BV1 solution count from 14 to eight, with all but one beyond the NEODyS 2080 time horizon, and lowered its overall BV1 risk ratings.

Correction:  The DOU also includes observations of 2004 BV1 from Jornada Observatory this morning in New Mexico that were used in today's updated assessments for this object. Thanks to David Dixon at Jornada for catching and reporting that this fact was missing from today's report.

None of the other objects currently in view that have impact solutions are reported in today's DOU.
