Earth's Busy Neighborhood

    ACC's Small Object Report for 15-21 January 2007    

A semi-automated report compiled on 21 January 2007 at 2359 UTC

Nine small asteroids were reported in the last 168 hours, during which three were newly discovered.*
*One was newly classified as small, and two almost-small objects are also included in this week's report.
Currently 1,219 NEAs are listed with H>22.0 by JPL and/or the MPC (1,036 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.

• Jan. 21:  Sunday's Daily Orbit Update (DOU) MPEC 2007-B26 reports observation of one small asteroid. Great Shefford Observatory in England more than doubled 2007 BD's observing arc from 1.720 to 4.390 days. Also reported are two borderline objects. Radar target 2006 AM4 was followed from Badlands Observatory in South Dakota and Greiner Research Obsservatory in Wisconsin observed 2006 UQ17.
• Jan. 20:  On Saturday there is an announcement of a small-asteroid discovery. 2007 BJ was found by LONEOS in Arizona yesterday morning UT and was confirmed overnight by Schiaparelli and Remanzacco observatories in Italy, Consell Observatory in Spain, and Jim Young at Table Mountain Observatory in southern California.
        Today's DOU MPEC 2007-B23 reports observations of three small asteroids. Farpoint Observatory in Kansas provided the first follow-up for risk-listed 2007 BB, catching it a bit more than nine hours before it passed Earth at one lunar distance, and extending its observing arc from about a quarter-day to two days. Consell tracked risk-listed 2006 XP4. And Begues Observatory in Spain added about three days to what had been 2007 AS2's eight-day observing arc. Also in the DOU is almost-small 2006 UQ17, reported from New Millennium Observatory in Italy early today.
• Jan. 19:  Friday DOU MPEC 2007-B17 reports observations of two small asteroids. 2007 AS2 was tracked by Hormersdorf Observatory in Germany and by the Mt. Lemmon Survey in Arizona. The Crimean Astrophysical Observatory in the Ukraine followed intruder 2007 BD, reporting 82 astrometric positions over a 2.80-hour period (averaging one position per 123 seconds) as this object approached Earth, and its discoverer, the Catalina Sky Survey in Arizona, picked up 2007 BD less than an hour after it had passed Earth at 0.8 lunar distance early yesterday UT. Also in today's DOU, Hamamatsu-Yuto Observatory in Japan observed smallish 2006 UQ17.
• Jan. 18:  DOU MPEC 2007-B16 on Thursday reports observation of one small asteroid. Gnosca and Modra observatories in Switzerland and Slovakia provided the first follow-up for intruder 2007 BD. Gnosca averaged about one position every six minutes during a 3.14-hour photometric run. Almost-small asteroid 2006 AM4 was observed from Spacewatch with its 0.9-meter telescope and 2006 UQ17 from University Hills Observatory in southern California.
• Jan. 17 #3:  Out of Arizona comes another small-asteroid discovery from the Catalina Sky Survey, this one from yesterday morning. Intruder 2007 BD was confirmed this morning by Andrushivka, Sabino Canyon, and Farpoint observatories in the Ukraine, Arizona, and Kansas, as well as by the CSS itself. JPL reports this object will fly past Earth at 0.8 lunar distance early tomorrow. It should stay in view for most NEO observers until around January 26th and awhile longer for larger telescopes.
• Jan. 17 #2:  The discovery of 2007 BB has been announced, discovered this morning and confirmed alone by the CSS, which followed it over a span of 6.77 hours. JPL is showing that this tiny object will pass Earth at about one lunar distance on January 19th. And the MPC is indicating that it will go out of view for all ground-based telescopes around the 23rd. Update: 2007 BB has been listed with a single far-off and very low-rated impact solution.
• Jan. 17 #1:  Wednesday's DOU MPEC 2007-B12 reports observations of one small asteroid. The Mt. Lemmon Survey (MLS) in Arizona yesterday morning and Farpoint Observatory in Kansas this morning added about three days to what had been 2007 AS2's five-day observing arc. Among not-quite small asteroids that are being included in reporting here, upcoming radar target 2006 AM4 was observed from the MLS and 2006 UQ17 from University Hills Observatory in southern California.
        Another smallish asteroid may have crossed the line. 2007 AA9 was first noticed by LINEAR in New Mexico, which tracked it for almost an hour on the morning of January 13th UT. The discovery was announced immediately following confirmation by Great Shefford Observatory in England early the next day. So far this week follow-up has been reported from both LINEAR and Great Shefford in Monday's DOU, from KLENOT in the Czech Republic in yesterday's DOU, and today from the CSS, to comprise an observing arc of just three days. The MPC's DOU and Ephemeris Service today put 2007 AA9's absolute magnitude at H=22.1, while the MPC's MPCORB data has it on the other side of the fence at H=21.9 along with JPL at H=21.98 and NEODyS at H=21.975.
• Jan. 16:  Tuesday's DOU MPEC 2007-B05 reports observations of four small asteroids. KLENOT in the Czech Republic tracked risk-listed 2006 XP4 and added about four days to 2007 AA2's three-day observing arc. Desert Moon Observatory in New Mexico added about sixteen days to 2006 XY's former nineteen-day arc. And Lumezzane Observatory in Italy observed 2007 AS2.
        The DOU also reports astrometry for two almost-small asteroids. KLENOT extended upcoming radar target 2006 AM4's second-opposition observing arc from one night to more than five and half days. And University Hills and Hamamatsu-Yuto observatories in southern California and Japan kept an eye on 2006 UQ17.
• Jan. 15:  Monday DOU MPEC 2007-A54 reports observations of two small asteroids. Great Shefford Observatory in England provided the first follow-up for 2007 AU2, adding three days to its two-day observing arc. Frasso Sabino Observatory in Italy observed 2007 AS2. And Hamamatsu-Yuto, University Hills, and Drebach observatories in Japan, southern California, and Germany followed smallish 2006 UQ17.

  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.
