Earth's Busy Neighborhood
ACC's Small Object Report for 27 February - 5 March 2006
A semi-automated report compiled on 5 March 2006 at 2359 UTC
There are 26* small objects reported in the last 168 hours, during which 11 were newly discovered.
*One other object with absolute magnitude just outside H=22.0 is also included in this week's report.
Currently 1011 NEAs are listed with H>22.0 by JPL and/or the Minor Planet Center (822 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 future exploration and
exploitation. They are mostly a sampling of distant asteroid populations, but
some 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 of 27 February through 5 March saw eleven small asteroid discoveries announced, which tally as eight from the Mt. Lemmon Survey in Arizona, two from its nearby sibling, the Catalina Sky Survey, and one from LINEAR in New Mexico. Nineteen observing facilities participated in tracking these and 15 other small asteroids plus one just outside the definition of "small." One discovery, 2006 DP62, started out as not-quite-small and barely scooched over the line by week's end. Nineteen observing facilities took part in the week's work, with Great Shefford Observatory leading amateur participation with confirmation and/or follow-up for eleven objects.
There were no known intruders during the week, but 2006 DM63 was discovered Monday after it had flown past the Earth at 0.61 lunar distance (LD) on the Friday before, and 2006 EC was discovered this Friday on its way into the Earth-Moon system to pass by next Wednesday at about 0.7 LD.
One of the more interesting discoveries this week is 2006 EB, which has a highly preliminary calculation of being an annnual visitor (and very low-rated impact hazard) in July of the next hundred years.
- Note: Last week ended with the announcement of what is nominally the 1,000th small-asteroid discovery as counted by A/CC. See a report about the count and the history plus other news from the week ending February 26th.
- March 5: The Sunday Minor Planet Center (MPC) Daily Orbit Update (DOU) Minor Planet Electronic Circular (MPEC) 2006-E17 reports observations of five small asteroids --
2006 CL9,
2006 DN,
2006 DU63, and the first follow-up for
2006 EC and
2006 EE.
- March 4 #2: Saturday's DOU MPEC 2006-E13 reports observations of eight small asteroids:
2006 CT,
2006 CW,
2006 DN,
2006 DP62,
2006 DO63,
2006 DU63, intruder
2006 EC and the first follow-up for 2006 DT63, which was listed as an impact risk until today.
- March 4 #1: Two more small-discoveries have been announced -- 2006 EC and 2006 EE. JPL is reporting that 2006 EC will pass Earth at 0.7 lunar distance on March 8th, and MPES is showing that it may remain in view until the 10th. The immediately previous announced discovery, 2006 EB, has now been posted as an impact risk with very low-rated and highly preliminary annual impact solutions for July of 2007 and the next hundred years.
- March 3 #2: The discovery of small asteroid 2006 EB has been announced today.
- March 3 #1: 2006 DP62 was delisted today as an impact risk. The Friday DOU MPEC 2006-E06 reports observations of two small asteroids: 2006 CL9 and 2006 CW9. The latter work, coded to Tim Spahr via Whipple Observatory in Arizona February 24th, is the first post-discovery arc observation of this object, which went out of view for most NEO observers around February 21st. It extends the observing arc from just over a day to about 19 days.
- March 2: Thursday's DOU MPEC 2006-E03 reports observations of ten small asteroids. There is the ongoing tracking of
2006 CL9, risk-listed
2006 DN,
2006 DO63, and
2006 DX from several observatories in Europe and the U.S., observations coded to Tim Spahr with the Whipple Observatory 1.2m telescope in Arizona of 2006 AW44,
2006 AX44, and
2006 BP7, all now out of view for most NEO observers, and, from Great Shefford Observatory in England, the first follow-up for
2006 DS62 and
2006 DU63 as well as risk-listed, borderline-small 2006 DP62.
- March 1: The discovery of small asteroid 2006 DU63 has been announced today, Wednesday, and observations are reported of ten more in DOU MPEC 2006-E01:
2006 BM55 from Feb. 4th,
2006 CL9,
2006 CW, risk-listed
2006 DL,
2006 DN (delisted as a risk today),
2006 DO63,
2006 DQ14,
2006 DR14,
2006 DU63 and borderline "small" 2006 BE55.
- Feb. 28 #3: Discovery of small asteroid 2006 DT63 is announced today. Update: more details added below, including risk-listing.
- Feb. 28 #2: Two more small-asteroid discoveries were announced today -- 2006 DM63 and 2006 DO63. JPL is reporting that 2006 DM63 flew through the Earth-Moon system and passed Earth at 0.6 lunar distance on 24 Feb., more than 73 hours before it was caught by the Mt. Lemmon Survey. MPES is predicting that it will go out of view around March 4th.
Observations are reported in Tuesday's DOU MPEC 2006-D60 of two small asteroids -- 2006 CW and
2006 DM.
- Feb. 28 #1: JPL has posted as impact risks small asteroids 2006 DO62 and 2006 DP62. While the MPC puts 2006 DP62's absolute magnitude at H=21.9 and the JPL's Solar Systems Dynamics site at 21.89, the JPL risk listing has it as H=22.4. Both objects were discovered by the Mt. Lemmon Survey in Arizona.
Update: NEODyS has also posted 2006 DO62 and 2006 DP62 as risks, and puts 2006 DP62 at H=21.894.
- Feb. 27 #2: Discoveries were announced today for small asteroids
2006 DO62,
2006 DR62, and
2006 DS62. Update: 2006 DO62 was discovered about 33 hours before this tiny object flew past Earth at about 2.0 lunar distances. It went out of view for most NEO observers late on the 26th.
- Feb. 27 #1: Monday's DOU MPEC reports observation of three small asteroids:
2006 CT,
2006 DN, and
2006 DU.

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.
