    ACC's Small Object Report for 9-15 January 2006    

A semi-automated report compiled on 16 January 2006 at 0001 UTC

There are 29* small objects reported in the last 168 hours, during which 8* were newly discovered.
*Two others with absolute magnitude H around 22.0, one a discovery, are also included in this week's report.
Currently 949 NEAs are listed with H>22.0 by JPL and/or the Minor Planet Center (779 are listed as such by both).

Editor's note:  "Small" is defined by an asteroid having an absolute magnitude (brightness) calculated at greater than H=22.0, or very roughly 135 meters in diameter. Larger H means lower size and the astronomical community does not classify such objects as "potentially hazardous" no matter how close they may come to the Earth. However, as demonstrated by the mile wide (1.6 km.) Barringer Crater in Arizona, blasted out by a "small" asteroid some 50,000 years ago, some asteroids too small to be labeled potentially hazardous could still cause severe local damage. These are sometimes called "Tunguska-class objects" (TCOs), after the 1908 event that was probably caused by a comet remnant or asteroid too small to be classified today as hazardous but packing enough wallop to flatten a Siberian forest area the size of a large city.
      NEODyS recently changed its main Risk page to qualify "Objects too small to result in heavy damage on the ground" as having "absolute magnitude > 25," which roughly corresponds to 35 meters wide. And JPL in October started flagging (with a blue background) risk-listed objects of "Estimated diameter 50 meters or less" as "not likely to cause significant damage in the event of an impact, although impact damage does depend heavily upon the specific (and usually unknown) physical properties of the object in question."
      The discovery and follow-up tracking of asteroids with H>22.0 represents some of the most difficult and very best observing work being done today by amateur and professional astronomers around the world, and the page you are reading is dedicated to recognizing their current successes.

Out-of-view date based on MPES solar elongation <40° and/or magnitude V>22.0 at 1200 UT. (Not factored in is any lunar interference with viewing.) Objects are linked in the left-most column only if observed in the last seven days, while objects with earlier small-object reporting are linked under "Notes." Diameter ("Dia") is in meters, a very rough estimate from brightness (H). Observing "Arc" is from MPES in days or number of oppositions.
