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: In the past seven days nineteen small asteroids were discovered and another eight were reported observed. The discoveries came from five observing facilities, with thirteen objects caught from Arizona -- eight from the Mt. Lemmon Survey, three from the Spacewatch 0.9-meter telescope, and two from the Catalina Sky Survey. Five came from LINEAR in New Mexico and one, fleeting 2006 XR4, came from KLENOT in the Czech Republic. Another fifteen facilities participated in the week's confirmation and follow-up work, led professionally by the Spacewatch 1.8-meter telescope in Arizona, reporting astrometry for fifteen objects, and on the amateur side by Great Shefford Observatory in England, reporting nine. The Spacewatch 1.8-meter also considerably extended the observing arcs of two asteroids this week that are no longer classified as small -- 2006 SP198 and 2006 SR19.
Another of the participating facilities was Lulin Observatory in Taiwan, which helped confirm two discoveries. This week it was brought to A/CC's attention by mainland China college student Quanzhi Ye that "nearly all" of Lulin's minor object observations reported since March 5th have come from the Lulin Sky Survey (LUSS) team, of which he is part.
Dec. 17: On Sunday the discoveries of five small asteroids have been announced. 2006 XV4 passed Earth at 5.2 lunar distances (per JPL) on Tuesday the 12th and was picked up from New Mexico 25 hours later by LINEAR, which alone confirmed the discovery yesterday morning. This object has now been listed with a single very low-rated impact solution. LINEAR discovered 2006 XW4 two mornings ago, confirmed by Great Shefford Observatory in England and in Arizona by the Mt. Lemmon Survey (MLS) and Sabino Canyon Observatory. The Catalina Sky Survey (CSS) in Arizona discovered 2006 YA yesterday morning, confirmed by Consell Observatory in Spain, MLS, and Sabino Canyon. And both 2006 YB and 2006 YE were discovered yesterday morning by the MLS and were confirmed by it and Great Shefford. JPL reports that 2006 YE passed Earth at 5.1 lunar distances about an hour and a half after discovery. It is calculated to go out of view for most NEO observers by next Friday, the 22nd, but will remain in view for larger telescopes for the rest of the month. Update: 2006 YE has been listed as a very low-rated impact risk.
Today's Daily Orbit Update (DOU) MPEC 2006-Y09 reports observations of seven small asteroids. MLS provided the first follow-up for 2006 XJ2 and tracked 2006 XA3. MLS and the Spacewatch 1.8-meter telescope in Arizona brought in the first follow-up for 2006 XY2 and also observed risk-listed 2006 XZ2. And Great Shefford reported the first follow-up for risk-listed 2006 XP4. 2006 XY was observed by CSS, MLS, and Great Shefford and 2006 XX2 by Buchloe Observatory in Germany. And KLENOT in the Czech Republic reported additional positions from its participation in 2006 XX2's discovery confirmation.
Dec. 16 #2: Saturday is closing out with one more small-asteroid discovery announcement. 2006 XR4 was discovered by KLENOT in the Czech Republic during 2047-2125 UT yesterday and confirmed today by the Catalina Sky and Siding Spring surveys in Arizona and Australia. JPL reports that it passed Earth at 1.6 lunar distances at 0612 this morning. 2006 XR4 is calculated to go out out of view for all ground-based optical telescopes in less than two days.
Dec. 16 #1: Saturday brings news of four small-asteroid discoveries. LINEAR discovered 2006 XN4 two mornings ago from New Mexico while the Mt. Lemmon Survey (MLS) in Arizona discovered and helped confirm the other three -- 2006 XO4 and 2006 XP4 on the 14th and 2006 XQ4 yesterday morning. The 2006 XN4 and 2006 XO4 discoveries were both confirmed by Sabino Canyon Observatory in Arizona along with 2006 XN4 by Robert Hutsebaut from New Mexico and 2006 XO4 by Gnosca Observatory in Italy. The Spacewatch 1.8-meter telescope in Arizona confirmed 2006 XP4, and KLENOT in the Czech Republic and Altschwendt Observatory in Austria confirmed 2006 XQ4. 2006 XP4 has been listed as an impact risk.
Today's DOU MPEC 2006-Y02 reports observations of six small asteroids. Of these that have been risk-listed, the Spacewatch 1.8-meter tracked 2006 WZ184 and provided the first follow-up for 2006 XZ2, and KLENOT turned in the first follow-up for 2006 XA3, which today was delisted as a risk. Powell Observatory in Kansas added about three days to the two-day observing arc of 2006 XW and with KLENOT reported the first follow-up for 2006 XX2. And LINEAR in New Mexico as well as KLENOT and Powell observed 2006 XY.
Dec. 15 #2: On Friday, DOU MPEC 2006-X70 reports observation of three small asteroids. The Mt. Lemmon Survey in Arizona provided the first follow-up for 2006 XH2 and together with KLENOT in the Czech Republic, Alter Satzberg Observatory in Austria, and Sandlot Observatory in Kansas doubled the observing arc of 2006 XY to about four days. And the Spacewatch 1.8-meter telescope in Arizona tracked 2006 XX.
Dec. 15 #1: Although it wasn't on the public schedule for radar observation from Arecibo in Puerto Rico, 2006 WB has been delisted as an impact risk following observation at 1515-1528 UT on December 14th. The data has been posted to JPL's asteroid Radar Astrometry page.
Dec. 14 #3: Discoveries four small asteroids have been announced. 2006 XX2 was discovered by LINEAR from New Mexico two mornings ago and was confirmed this morning and this evening. 2006 XY2 was discovered yesterday with the Spacewatch 0.9m telescope in Arizona. And 2006 XZ2 and 2006 XA3 were also discovered yesterday in Arizona, by the Mt. Lemmon Survey which alone confirmed them today. According to JPL's first calculations, three of these will be or have been within 4.8 to 8.6 lunar distances of Earth during 5-22 December. The other, 2006 XY2, is calculated to stay much further away. Update: The two MLS discoveries, 2006 XA3 and 2006 XZ2, have been listed as impact risks.
Dec. 14 #2: Thursday DOU MPEC 2006-X64 reports observations of three small asteroids. Spacewatch used its 1.8-meter telescope in Arizona to track risk-listed 2006 WZ184 as well as 2006 WX3, and Hibiscus Observatory in Tahiti observed 2006 XY.
The Spacewatch 1.8-meter also added about 22 days to what had been a 56-day observing arc for distant 2006 SP198, which is no longer classified as small.
Dec. 14 #1: Discoveries of two small asteroids have been announced, both found during the morning of December 12th UT -- 2006 XH2 by LINEAR in New Mexico and 2006 XJ2 by the Mt. Lemmon Survey in Arizona.
Dec. 13: DOU MPEC 2006-X52 on Wednesday reports observations of five small asteroids. Spacewatch used its 1.8-meter telescope in Arizona to observe 2006 XX and to add about 31 days to the the 26-day observing arc of 2006 UE, which just went out of view for most NEO observers. Powell Observatory in Kansas tracked risk-listed 2006 WK130. The first follow-up for 2006 XY came in from the Catalina Sky Survey in Arizona along with Great Shefford Observatory in England, which also reported 2006 XW.
No longer classified as "small," distant 2006 SR19 had its observing arc upped from about 58 to now 84 days with the Spacewatch 1.8-meter. This object is calculated to go out of view for most NEO observers later in the week.
Dec. 12: Tuesday DOU MPEC 2006-X39 reports observation of nine small asteroids. Spacewatch used its 1.8-meter telescope in Arizona to add about 30 days to the former 40-day observing arc of 2006 TO and 43 days to 2006 UT17's nine-day arc, to double 2006 WX3's arc to twenty days and add ten days to 2006 WB30's seven-day arc, and also to track risk-listed 2006 WK130 and provide the first follow-up for 2006 XW. In England, Great Shefford Observatory provided the first follow-up for 2006 XX, added about thirteen days to 2006 WM3's nine-day observing arc, and, along with the Spacewatch 1.8-meter, kept watch on risk-listed 2006 WZ184.
Dec. 11 #2: Discoveries from Arizona of three small asteroids have been announced today. 2006 XW and 2006 XX were found with the Spacewatch 0.9-meter telescope yesterday morning UT and 2006 XY was discovered by the Catalina Sky Survey this morning.
Dec. 11 #1: On Monday, DOU 2006-X29 reports observation of one small asteroid. The Spacewatch 1.8-meter telescope in Arizona kept watch on risk-listed 2006 WZ184.

  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.
