Earth's Busy Neighborhood
ACC's Small Object Report for 27 Nov. - 3 Dec. 2006
A semi-automated report compiled on 3 December 2006 at 2359 UTC
Twenty-six small asteroids were reported in the last 168 hours, during which eight were newly discovered.
Currently 1,187 NEAs are listed with H>22.0 by JPL and/or the MPC (1,004 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.

- Note: We passed two mile stones this week. One was that the count of known small asteroids went past one thousand. And this, what you are reading, is A/CC's 52nd consecutive weekly small object report in a year now of focusing on this very challenging observational work. In the first report a year ago, the count was 755 asteroids that both the Minor Planet Center and JPL classified then as small, so today's 1,004 is an increase by one-fourth in just a year. Still, there are many times more small asteroids passing in close proximity to the Earth and Moon and only one has been observed well enough yet to be assigned an IAU number.
- Dec. 3: On Sunday the Daily Orbit Update (DOU) MPEC 2006-X12 reports observations of three small asteroids. Risk-listed 2006 WB was tracked by University Hills Observatory in southern California. Schiaparelli Observatory in Italy provided the first follow-up for 2006 WJ130, adding about two days to its one-day discovery arc. And Great Shefford Observatory in England, along with Schiaparelli, added about four days to what had been a seven-day observing arc for 2006 WS29.
- Dec. 2: Saturday's DOU MPEC 2006-X11 carries observations of six small asteroids, all from Arizona. Spacewatch used its 1.8-meter telescope to track rist-listed 2006 WB and 2006 WK130, the Mt. Lemmon Survey followed risk-listed 2006 WC30 as well as 2006 WH130, and both observed 2006 WB30 and 2006 WX3.
- Dec. 1: On Friday, the discovery of small asteroid 2006 WZ184 has been announced. It was discovered by LINEAR from New Mexico Tuesday morning, November 28th, but not confirmed until the Mt. Lemmon Survey in Arizona caught it this morning. JPL reports that this object passed Earth at 5.9 lunar distances on November 26th. Update: 2006 WZ184 has been listed as impact risk.
Today's DOU MPEC 2006-X01 carries observations of four small asteroids. Hibiscus Observatory in Tahiti provided the first follow-up on 2006 WH130, it and the Spacewatch 1.8-meter telescope in Arizona did the same for risk-listed 2006 WK130, and Hibiscus also kept watch on 2006 WP3. And LINEAR in New Mexico brought in the first follow-up for 2006 WR29, adding about four days to that object's two-day discovery arc.
- Nov. 30: On Thursday there is an announcement of newly discovered small asteroid 2006 WO130, which was found Monday morning by the Mt. Lemmon Survey (MLS) in Arizona at 0616 and confirmed by only a second set of MLS observations ending at 0754 UT, an observing arc of just one hour and 38 minutes. From its MPC ephemeris, this object will be inside nine lunar distances of Earth from 0500 on December 3rd to 1400 on the 4th, and will go out of view for most NEO observers four days after that and for all ground-based optical telescopes a week or so later.
Observations of five small asteroids are reported in today's DOU MPEC 2006-W114.
LINEAR tracked 2006 WM3 from New Mexico and provided additional astrometry from within the discovery arc of 2006 WJ130. It also reported 2006 VB45 from four days before its discovery, thus doubling the observation arc for that object, which hasn't been reported observed since November 19th. Desert Moon Observatory in New Mexico and Spacewatch in Arizona with its 1.8-meter telescope added three days to what had been a six-day observing arc for 2006 WX3. And Great Shefford Observatory in England added five days to 2006 WS29's two-day arc.
- Nov. 29: Wednesday brings news of four small-asteroid discoveries. 2006 WG130, 2006 WH130, and 2006 WJ130 were found by LINEAR from New Mexico, and 2006 WK130 by the Mt. Lemmon Survey in Arizona. Great Shefford Observatory in England was in on confirming all four, Hibiscus Observatory in Tahiti helped confirm 2006 WH130 and WJ130, Sabino Canyon Observatory in Arizona caught 2006 WG130 and WH130, and Golden Hill Observatory in England reported 2006 WG130. Update: 2006 WK130 has been listed as an impact risk.
Observations are reported of three other small asteroids in today's DOU MPEC 2006-W109. The first follow-up for 2006 WC30 was provided by Great Shefford, adding three days to its one-day discovery arc. The Spacewatch 1.8-meter telescope tracked risk-listed 2006 WB. And 2006 UN was observed from Whipple Observatory in Arizona, with that astrometry coded to Tim Spahr.
1,000th small asteroid: With today's discovery announcements, the number of asteroids classified as small (H>22.0) by both the Minor Planet Center and JPL for the first time exceeds one thousand, now totalling 1,002. By A/CC's reckoning, the honor of 1,000th small asteroid goes to 2006 WH130. There are also, as of today, an additional 183 asteroids that are classified as small by either JPL or the MPC but not by both. There would be more except that two asteroids last week were reclassified as being outside the definition of small.
- Nov. 28: On Tuesday the discovery of one small asteroid has been announced. 2006 WD129 was discovered Saturday morning by the Mt. Lemmon Survey (MLS) in Arizona and confirmed that night by Great Shefford Observatory in England and by the MLS yesterday morning, and will go out of view in about two days.
Today's DOU MPEC 2006-W103 reports
observation of nine small asteroids. 2006 BZ147 was recovered with the Spacewatch 1.8-meter telescope yesterday and today was delisted as an impact risk. This telescope also tracked risk-listed 2006 WB, provided the first follow-up on minimally observed 2006 WU1, bringing its observing arc up from one to eight days, extended 2006 WX's four-day arc to nine days, and observed 2006 UC185, while the Spacewatch 0.9-meter telescope tracked 2006 WX3. Hibiscus Observatory in Tahiti added five days to little-observed 2006 WP3's two-day arc and also observed 2006 VP13. And the Mt. Lemmon Survey reported departed intruder 2006 WX29 from within its discovery arc.
- Nov. 27: On Monday the discovery of small asteroid 2006 WQ127 has been announced. It was discovered Saturday morning by the Catalina Sky Survey in Arizona and will go out of view after passing Earth next Saturday at about 7.8 lunar distances. Participating in the discovery confirmation were the Siding Spring Survey in Australia and Hibiscus and Sabino Canyon observatories in Tahiti and Arizona.
Today's DOU MPEC 2006-W94 reports observations of five other small asteroids. Spacewatch in Arizona used its 1.8-meter telescope to track risk-listed 2006 WB and 2006 WZ29. That was the first follow-up for 2006 WZ29, which goes out of view soon for most NEO observers, doubling its observing arc to about four days. The same instrument also reported the first follow-up observations for 2006 VU2, which also goes out of view soon, and for 2006 WX3, adding about fourteen days to VU2's two-day observing arc and six days to WX3's one-day arc. And the telescope was joined by Guidestar Observatory in Germany with observing 2006 WM3.

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 are the best hopes.
