Earth's Busy Neighborhood
ACC's Small Object Report for 29 May - 4 June 2006
A semi-automated report compiled on 4 June 2006 at 2359 UTC
There are 16 small asteroids reported in the last 168 hours, during which nine were newly discovered.
Currently 1,065 NEAs are listed with H>22.0 by JPL and/or the MPC (887 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: This past week nine small asteroids were discovered and observations of another five were reported, plus one from 2004. And the total count of small asteroids was reduced by one with the announcement that well-observed 2005 YM128 is actually the lost 1997 YM9.
Seven of the discoveries came from the Mt. Lemmon Survey (MLS) in Arizona and one from its neighboring affiliate, the Catalina Sky Survey. The other came from the Spacewatch 0.9m telescope, also in Arizona. Fourteen observing facilities participated in the week's work, plus one with astrometry from 2004.
Distant small asteroids: Two MLS discoveries this week are calculated to come no closer to Earth than 56 lunar distances (LD). This brings up the question of how deep is the population of small asteroids being detected. One can get an idea from JPL's NEO Orbital Elements table, which presently lists 1,035 asteroids as having absolute magnitude H>22.0, thus defined as "small." Of these, 61 have minimum orbit intersection distances (MOIDs) of 50+ LD, and eleven have an MOID greater than 100 LD. The champion is 2001 QE96 at 116.7 LD, and the only such discovery so far this year, 2006 EJ53, is fourth most distant at 111.4 LD. (The largest Earth MOID for any of the 4,055 asteroids in the JPL NEO table is 0.699175 AU = 272 LD.)
- June 4: The Sunday Daily Orbit Update (DOU) MPEC 2006-L25 reports observations of six small asteroids. UKAPP in Northern Ireland employed the Faulkes Telescope North in Hawaii to provide the first follow-up for 2006 KC40, adding a week to a two-day observation arc and getting this object removed as an impact risk. Yesterday morning's discovery, 2006 LM, was caught last night by Great Shefford Observatory in England, which also observed 2006 LC. And Farpoint Observatory picked up 2006 KK103, adding three days to a six-day arc. Also tracked were 2006 KY67 from Naef Observatory in Switzerland and, from May 29th, 2006 KM89 from Andrushivka Observatory in the Ukraine.
- June 3 #1: Discovery of small asteroid 2006 LM has been announced today, found this morning by the Catalina Sky Survey in Arizona and confirmed by the Siding Spring Survey in Australia over a span of not quite three hours. JPL reports that this object will pass Earth at 3.2 to 3.7 or more lunar distances sometime on June 7th (there is a four-hour window in the calculation due to an extremely short observation arc). It is initially calculated to go out of view for most NEO observers a week later.
- June 3 #1: Saturday's DOU MPEC 2006-L23 carries astrometry for three small asteroids. Farpoint Observatory in Kansas provided the first follow-up on 2006 KL103 and 2006 LC, and Naef Observatory in Switzerland tracked 2006 KY67.
- June 2 #2: There is one less small asteroid today. MPEC 2006-L19 identifies 2005 YM128 as being 1997 YM9 rediscovered. 2005 YM128 was found by the Mt. Lemmon Survey December 30th and has been subsequently observed for 125 days, from as recently as May 4th, and remains in view even now. 1997 YM9 was first noticed by JPL's NEAT program, using a U.S. Air Force telescope on Haleakala in Hawaii on 28 December 1997 (see MPEC 1997-Y21), and was followed for a period of 13 days at that time.
- June 2 #1: Friday brings discovery announcements for three small asteroids and observations of four others. The discoveries were all from Arizona yesterday morning UT at the Mt. Lemmon Survey (MLS). 2006 LB and 2006 LC were announced a little before today's DOU MPEC was issued, while 2006 LD was announced in the DOU itself, time-stamped 0613 UT, and then received its own discovery MPEC at 0928 UT with additional observations.
DOU MPEC 2006-L08 shows that small asteroid 2006 CT, which until now had a 32.020-day observing arc and has been in view only for large telescopes since mid-March, was observed by David Tholen's team on Mauna Kea in Hawaii back in September of 2004. Three positions spanning 16 minutes are reported from 503.8 days before this object's February discovery.
Also reported in today's DOU are 2006 KJ89 and
2006 KY67 from Great Shefford Observatory in England, adding two days to what were five-day observing arcs for both, and MLS kept track of 2006 KK103, doubling its arc to six days.
- June 1 #2: Discovery of 2006 KL103 has been announced today with an MPEC time stamp of 1617 UT, only a few minutes before reaching its closest point on this Earth passage, at somewhere around 15 lunar distances according to JPL. This small asteroid was first spotted yesterday morning by the Mt. Lemmon Survey in Arizona.
- June 1 #1: Thursday's DOU MPEC 2006-L01 carries observations of two small asteroids. Great Shefford Observatory in England provided the first follow-up on 2006 KM89. The Mt. Lemmon Survey (MLS) reported observations from May 29th of 2006 KK103, the discovery of which on May 26th and confirmation on the 28th, all by MLS alone, was announced on the 31st. This object was approaching Earth at about 74 lunar distances (LD) on the 29th, and is initially calculated to never come closer than 55 LD in its current orbit.
- May 31 #2: Discovery of small asteroid 2006 KK103 has been announced today, found on the morning of May 26th by the Mt. Lemmon Survey, which confirmed the find two mornings later.
- May 31 #1: Observations of six small asteroids are reported in Wednesday DOU MPEC 2006-K81. From southern New Mexico, 2006 KC was tracked from Desert Moon Observatory and 2006 KQ1 and 2006 KS1 from Jornada Observatory. In England, Great Shefford Observatory provided the first follow-up on new discoveries 2006 KJ89 and 2006 KM89, and also reported 2006 KY67.
- May 30: Discoveries of three small asteroids have been announced on Tuesday:
2006 KJ89,
2006 KK89, and
2006 KM89.
One was found with the Spacewatch 0.9m telescope and the other two by the Mt. Lemmon Survey, all from Arizona. None these objects are calculated to come closer to Earth than 35 lunar distances.
2006 KQ1 was reported in today's DOU MPEC 2006-K72 as observed yesterday morning with the Spacewatch 1.8m telescope along with 2006 KY67, which was delisted today as an impact risk.
- May 29: Monday's DOU MPEC 2006-K65 reports observation of one small asteroid. The Spacewatch 1.8m telescope was used to add another seven days to what had been a 28-day observing arc for 2006 HW50.

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.
