Earth's Busy Neighborhood
ACC's Small Object Report for 18-24 September 2006
A semi-automated report compiled for 24 September 2006
Nineteen small asteroids were reported in the last 168 hours, during which ten were newly discovered.
Currently 1,104 NEAs are listed with H>22.0 by JPL and/or the MPC (920 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 is a preliminary version of this page, with some more polishing to do and the week-in-review write-up still to come.
- Sept. 24: Sunday's Daily Orbit Update (DOU) MPEC 2006-S55 reports observations of six small asteroids. The Spacewatch 0.9- and 1.8-meter telescopes in Arizona and Table Mountain Observatory in southern California provided the first follow-up for two of them, adding about four days to 2006 SG7's one-day observing arc and three days to 2006 SP19's one-day arc. The Spacewatch 1.8m telescope also added about eight days to what had been a 27-day arc for 2006 QX5. Table Mountain and Modra Observatory in Slovakia extended 2006 SK61's arc of less than a day by almost 23 hours. 2006 SE6 was reported from the Spacewatch 1.8m and from McDonald Observatory in Texas. And 2006 SF7 was tracked by Drebach Observatory in Germany.
- Sept. 23: The Saturday DOU MPEC 2006-S54 reports observations of nine small asteroids. Wildberg, Linz, Great Shefford, and La Canada observatories in Germany, Austria, England, and Spain caught 2006 SK61, which was delisted today as an impact risk. McDonald Observatory in Texas tracked risk-listed 2006 RJ1 and 2006 SC, which was also observed by KLENOT in the Czech Republic.
2004 SC56 was followed from Germany by Buchloe Observatory, which with KLENOT also observed 2006 SE6.
2006 SD25 was followed by KLENOT, 2006 SF7 by Modra Observatory in Slovakia, 2006 SV5 by Greiner Research Observatory in Wisconsin and KLENOT, and Great Shefford and KLENOT added about three days to 2006 SQ19's one-day observing arc.
- Sept. 22 #1: Discovery of small asteroid 2006 SK61 has been announced, discovered this morning by LONEOS in Arizona and confirmed this evening by Andrushivka Observatory in the Ukraine. This object, which JPL reports passed Earth at 5.6 lunar distances yesterday, has been posted with a single very low-rated impact solution.
- Sept. 22 #1: On Friday, DOU MPEC 2006-S41 reports observation of seven small asteroids. 2006 SD25 was delisted today as an impact risk after being pursued yesterday morning UT by LONEOS in Arizona and Petit Jean Mountain South Observatory in Arkansas and last night by Guidestar, Herrenberg, and Drebach observatories in Germany, Eschenberg Observatory in Switzerland, and KLENOT in the Czech Republic.
Drebach Observatory also tracked 2004 SC56. Kanab Observatory in Utah along with Guidestar Observatory and KLENOT observed 2006 SC. KLENOT added about two days to what had been a three-day observing arc for 2006 SE6 and doubled the arc for 2006 SV5 to about six days. Eschenberg Observatory followed 2006 SF7. And Herrenberg, Eschenberg, and Drebach observatories kept after 2006 SY5.
- Sept. 21 #2: Thursday DOU MPEC 2006-S36 reports observations of six small asteroids. The Catalina Sky Survey in Arizona added 2.955 days to what had been a 1.054-day arc for 2004 SC56 on its second apparition and added about three hours to 2006 SQ19's discovery arc. Altschwendt Observatory in Austria provided the first follow-up for risk-listed 2006 SD25. Wildberg Observatory in Germany brought the observing arc for 2006 SF7 up to about four days. Observations were reported from within the discovery arc of 2006 SP19 by Great Shefford Observatory in England. And Petit Jean Mountain South Observatory in Arkansas doubled the observing arc for 2006 SY5 to about four days.
- Sept. 21 #1: 2006 SD25 has been posted as an impact risk.
- Sept. 20 #3: Discovery of small asteroid 2006 SD25 has has been announced late today UT, found this morning by the Catalina Sky Survey in Arizona and confirmed this evening by Wildberg Observatory in Germany.
- Sept. 20 #2, observer alert: JPL is requesting astrometry and photometry for 2006 RZ ahead of radar observations planned early next month on the occasion of its flying past Earth at 4.9 lunar distances (LD) on October 7th. The JPL planning page states that "Goldstone observations are scheduled on October 4 and 5. We are also trying to schedule observations at Arecibo. The most likely dates are October 1-3 and 7 and 8." At absolute magnitude (brightness) H=20.1, this formerly risk-listed asteroid is not particularly large but neither does it fall within the definition of "small." Either way, this page is also used by A/CC to report on objects of any size observed passing within ten LD.
- Sept. 20 #1: On Wednesday the discoveries of two small asteroids have been announced. Both were found yesterday morning UT in Arizona, 2006 SP19 with the Spacewatch 0.9m telescope and 2006 SQ19 by the Catalina Sky Survey. Powell Observatory in Kansas and the Spacewatch 1.8m telescope provided confirmation for 2006 SP19 this morning, and Powell closed out the confirmation process for 2006 SQ19 which included Table Mountain Observatory yesterday morning in southern Calfornia, Gnosca and Great Shefford observatories last night in Switzerland and England, and Farpoint and Desert Moon observatories this morning in Kansas and New Mexico. JPL has a preliminary calculation that 2006 SQ19 doesn't come closer to Earth than 58-plus lunar distances, which is rather distant as small asteroids go.
Today's DOU MPEC 2006-S27 reports observations of six small asteroids. Risk-listed risk-listed 2006 RJ1 was tracked by Jornada and Naef observatories in New Mexico and Switzerland, and 2006 SC, also on the risk lists, was followed by Petit Jean Mountain South and Consell observatories in Arkansas and Spain, doubling that object's observation arc to about four days.
LINEAR in New Mexico reported 2006 RJ7 from within its current observing arc, LONEOS in Arizona, the Spacewatch 0.9m telescope, and Consell Observatory tracked 2006 SE6, and Desert Moon and Table Mountain followed 2006 SF7. And 2006 SV5, which is calculated to be in view until January, was observed from Kanab Observatory in Utah and Petit Jean Mountain.
- Sept. 19: On Tuesday discoveries from Arizona of two small asteroids have been announced. The Catalina Sky Survey (CSS) found 2006 SF7 two mornings ago and caught it again yesterday morning UT. That was just before the Spacewatch 0.9m telescope found 2006 SG7. This was quickly confirmed with the Spacewatch 1.8m telescope, which also caught it today. Confirmation also came this morning for both objects from Farpoint and Grasslands observatories in Kansas and Arizona, for 2006 SF7 from Gnosca and Great Shefford observatories in Switzerland and England, and for 2006 SG7 from CSS.
Today's DOU MPEC 2006-S21 reports observations of six small asteroids. The Spacewatch 1.8m telescope was used to add about 28 days to what had been a 32-day observing arc for 2006 OY4. Further observations were reported from yesterday for 2006 QJ65 from LONEOS in Arizona and the Siding Spring Survey in New South Wales within this object's rediscovery arc. 2006 RJ1 was tracked with the Spacewatch 1.8m telescope and by LONEOS. Great Shefford added about three days to 2006 RJ7's one-day observing arc and also tracked 2006 SB, which passes Earth today at 3.8 lunar distances. And LINEAR in New Mexico reported 2006 SE6 from within its discovery arc.
- Sept. 18 #4: Three more small-asteroid discoveries have been announced today from Arizona -- 2006 SV5 found early on the 16th UT with the Spacewatch 0.9m telescope and soon after 2006 SY5 by the Catalina Sky Survey (CSS). And the Spacewatch 1.8m telescope discovered 2006 SE6 yesterday morning. Farpoint and Table Mountain observatories in Kansas and southern California took part in confirming all three discoveries, while Sabino Canyon Observatory was in on confirming 2006 SY5 and 2006 SE6, and CSS and the Siding Spring Survey confirmed both 2006 SV5 and 2006 SE. 2006 SV5 was additionally confirmed with the Spacewatch 1.8m telescope, by Antares and Pla D'Arguines observatories in South Carolina and Spain, and by Grasslands and Kanab observatories in Arizona and Utah.
- Sept. 18 #3: Discovery of small asteroid 2006 QJ65 has been indicated today, but without full details or credit. It was posted to the NEO Confirmation Page yesterday with a temporary designation from LONEOS in Arizona, and today's MPEC reports "additional observations" from LONEOS yesterday morning and confirmation overnight and today from Uruguay, the U.S., and Australia. The residuals section of the MPEC shows that this object was observed by the Spacewatch 1.8m telescope on August 27th and by its sibling 0.9m telescope on the 28th.
- Sept. 18 #2: Monday DOU MPEC 2006-S11 carries observations of three small asteroids. The Spacewatch 1.8m telescope in Arizona tracked risk-listed 2006 RJ1 and 2006 SC, and David Tholen's team on Mauna Kea in Hawaii reported 2006 OC7 from August within that object's observing arc.
- Sept. 18 #1: On September 18th UT, but still the 17th in Pasadena, JPL has posted 2006 SC as an impact risk.
- See news from the week of 11 to 17 September and from previous weeks, and you also can look up individual small asteroids.

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.
