Earth's Busy Neighborhood

    ACC's Small Object Report for 1-7 May 2006    

A semi-automated report compiled on 7 May 2006 at 2359 UTC

There are 18 small asteroids reported in the last 168 hours, during which five were newly discovered.
Currently 1,046 NEAs are listed with H>22.0 by JPL and/or the MPC (867 are listed as such by both).

Editor's note:  As asteroids go, "small" is defined as having an absolute magnitude (brightness) calculated at greater than H=22.0, which converts very roughly to a diameter under 135 meters. No matter how close they come to the Earth, the astronomical community does not classify such objects as "potentially hazardous." 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, there are asteroids too small to be labeled "potentially hazardous" that actually could cause severe local damage. These are sometimes called "Tunguska-class objects" (TCOs), after the 1908 event probably caused by a comet fragment 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 in December 2005 changed its main Risk page to classify "Objects too small to result in heavy damage on the ground" as having "absolute magnitude > 25," which corresponds to perhaps 35 meters wide. And JPL two months earlier 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."
      Small asteroids that come close enough to Earth to be seen have significant potential for scientific study today, and for exploration and exploitation in the future. They present a sampling of distant asteroid populations and a few may be remnants of the event that created the Earth-Moon system.
      Some of these objects are discovered while close to Earth moving across the sky quite quickly, when they are called "FMOs" or "VFMOs" (very fast moving objects). 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 ongoing successes.

• Week in Review:  Five small asteroids were discovered this past week, three by the Mt. Lemmon Survey (MLS) and one by LONEOS, both located in Arizona, and one by LINEAR, located in Massachusetts and observing remotely from New Mexico. Astrometry was also reported for 15 other small asteroids. Thirty-one observing facilities participated in this work, each observing one to four objects, except for Mt. John Observatory in New Zealand, which tracked five, and MLS, which observed six more beyond the three it discovered.
        Recoveries and major extensions to short observing arcs are rare for small asteroids, so, by that measure, this was a very good week. David Tholen's team on Mauna Kea in Hawaii recovered 2000 SJ344 for a third opposition, and two discoveries from late December were picked up again. Joel Parker at Kitt Peak National Observatory in Arizona added 112 days to 2005 YM128's 13-day observing arc, and the Spacewatch 1.8m telescope, also on Kitt Peak, was used to add 102 days to 2005 YA37's 26-day arc.
• May 7:  The Sunday Daily Orbit Update (DOU) MPEC 2006-J32 reports observation of six small asteroids. Linz Observatory in Austria has a single position for 2005 YM128 from May 2nd, helping to nail down this end of a now 125-day observing arc. The Spacewatch 1.8m telescope in Arizona was used to add four days to the eleven-day arc for 2006 HF6, which is risk-listed and about to go out of view. Also risk-listed and soon disappearing is 2006 HX57, which Great Shefford Observatory in England observed thirteen-plus hours before this object passed Earth yesterday at 3.0 lunar distances. Also tracked from the Ukraine, Spain, and Arizona were 2006 HU50, 2006 HW50, and 2006 JM6.
• May 6:  Discovery of one small asteroid has been announced today. 2006 JM6 was discovered yesterday morning by the Mt. Lemmon Survey in Arizona and confirmed overnight. And observation of one small asteroid, risk-listed 2006 HX57, is reported in Saturday's DOU MPEC 2006-J26. 2006 HX57 passes Earth today at 3.0 lunar distances.
• May 5:  On Friday, DOU MPEC 2006-J24 reports observations of four small asteroids. Astrometry coded to Joel Parker of Southwest Research Institute, using one of the large telescopes at Kitt Peak National Observatory in Arizona, added about 112 days to 2005 YM128's 13-day observing arc. And 2006 HU50, 2006 HW50, and risk-rated 2006 HX57 were followed from Belgium, Austria, and Northern Ireland. In Belgium, Thierry Pauwels participated from Uccle Observatory and Robert Hutsebaut from his Brussels home operating a telescope in New Mexico.
• May 4:  Thursday's DOU MPEC 2006-J21 reports observations of six small asteroids. The Spacewatch 1.8m telescope in Arizona picked up 2005 YA37, adding 102 days to a 26-day observing arc. Mt. John Observatory in New Zealand added about seven days to 2006 HW5's six-day arc, and the sibling Siding Spring and Mt. Lemmon surveys in Australia and Arizona added about four days to 2006 HV50's three-day arc. Also tracked were 2006 FH36 and the quickly departing 2006 JE and 2006 JO.
• May 3 #2:  There are announcements of two small-asteroid discoveries, 2006 JO and 2006 JP, both found yesterday morning by the Mt. Lemmon Survey in Arizona and confirmed this morning. Early calculations have 2006 JO passing Earth at about 4.8 lunar distances on May 6th, per JPL, and going out of view two days later, per MPES.
• May 3 #1:  On Wednesday, DOU MPEC 2006-J15 reports observations of seven small asteroids: 2006 HF6, 2006 HH56, 2006 HU50, 2006 HW50, 2006 HX30, 2006 HX57, and 2006 HZ5.
• May 2 #2:  Discovery of 2006 JE has been announced today, caught by LINEAR in New Mexico yesterday morning and confirmed overnight. JPL reports that it passed Earth today at 8.4 lunar distances.
  Update: JPL has posted 2006 JE as a far-off, low-rated impact risk. This object is going to out of view for all ground-based optical telescopes in the next one to three days.
• May 2 #1:  Tuesday's DOU MPEC 2006-J11 reports observations of five small asteroids. David Tholen's team on Mauna Kea in Hawaii has again recovered 2000 SJ344, catching it on April 30th at third opposition. See small object news from the past month for a report of the team recovering 2000 SJ344 at second opposition last year. Previous to that it had had a 200-day observing arc from 2000 to 2001.
        Mt. John Observatory in New Zealand added about four days to what had been a eight-day arc for 2006 HC and, along with Great Shefford Observatory in England and LINEAR in New Mexico, helped add about four day's to 2006 HW50's five-day arc. Also tracked were 2006 FH36 and 2006 HZ5.
• May 1:  Discovery of one small asteroid is reported today. 2006 HX57 was found and followed yesterday morning by LONEOS in Arizona, was also picked up by LINEAR in New Mexico, and was confirmed overnight by eight other observing facilities.
  Updates: JPL reports that 2006 HX57 will pass Earth at about 3.0 lunar distances on May 6th, and JPL has posted this object as a very low-rated impact risk.
        Monday DOU MPEC 2006-J01 reports observations of three small asteroids -- 2006 FH36, 2006 HH56, and 2006 HU50 -- with one each from Andrushivka, Los Molinos, and Jornada observatories in the Ukraine, Uruguay, and U.S.

  Out-of-view date based on MPES solar elongation <40° and/or magnitude V>22.0 at 1200 UT
    geocentric. (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.
  "In view" does not necessarily mean locatable for objects with short arcs in prior years,
    and for which a large search or accidental rediscovery may be the best hope.
