Earth's Busy Neighborhood
ACC's Small Object Report for 26 March - 1 April 2007
A semi-automated report compiled on 1 April 2007 at 2359 UTC
Thirteen small asteroids were reported in the last 168 hours, during which one was newly discovered.
Currently 1,291 NEAs are listed with H>22.0 by JPL and/or the MPC (1,109 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.

- April 1: On Sunday, Daily Orbit Update (DOU) MPEC 2007-G01 reports observation of one small asteroid. Great Shefford Observatory in England last night added about four days to the two-day observing arc of risk-listed 2007 FY20. This object will pass Earth tomorrow night at 5.3 lunar distances and goes out of view a day or so later.
- March 31: Saturday's DOU MPEC 2007-F91 carries astrometry for one small asteroid. BlackBird Observatory in New Mexico reported risk-listed radar target 2007 FY20 from early on March 27th UT.
- March 30: No observations of small asteroids have been reported on Friday.
The JPL Radar Astrometry page has been updated as of March 28th to report that kilometer-size, close-passing asteroid 2006 VV2 (see report below) was successfully observed from Goldstone in southern California on March 27th. This was the first step in a major radar observation campaign. See 2006 VV2 news links for more about tonight's close passage.
JPL's radar database additionally shows that tiny intruder 2006 EH was observed from Arecibo in Puerto Rico on March 11th, adding 13.43 hours to its 44.87-hour optical observation arc. Earlier that day 2006 EH flew through the Earth-Moon system at one-half lunar distance.
Also shown now is radar observation of 2006 UQ17 from Arecibo on January 29th. This asteroid, which doesn't quite meet the definition of "small," was last reported observed optically early this month, bringing its observation arc up to 162 days. It goes out of view for even large telescopes this week.
Arecibo's schedule has 2007 FY20 as a target for tomorrow. This risk-listed small asteroid will be in view for only about nine days following its March 26th discovery.
- March 29: Thursday DOU MPEC 2007-F82 reports observation of one small asteroid. 2007 EJ88 was tracked by the Mt. Lemmon Survey in Arizona.
- March 28: Wednesday's DOU MPEC 2007-F81 reports observations of two small asteroids. The first follow-up for risk-listed and soon-to-disappear 2007 FY20 comes from its discoverer, the Catalina Sky Survey in Arizona, and two of the observatories that helped confirm its discovery, Guidestar and Bergen-Enkheim in Germany. And 2007 EJ88 is reported from England from March 22nd by Great Shefford Observatory and from Arizona on the 26th with the Spacewatch 1.8-meter telescope and yesterday morning by the Mt. Lemmon Survey.
- March 27: On Tuesday, DOU MPEC 2007-F79 reports observations of four small asteroids. Linz Observatory in Austria provided the first follow-up for 2007 FJ1, adding about seven days to its two-day observing arc. Spacewatch in Arizona used its 1.8-meter telescope to extend 2007 DX60's observing arc from about 25 to 33 days, and to add about seventeen days to the sixteen-day arc of 2007 DH8, which is calculated to go out of view for most NEO observers tomorrow. In yesterday's announcement MPEC, three positions spanning 12.3 minutes from Bergen-Enkheim Observatory in Germany closed out 2007 FY20's discovery arc. Today's DOU reports five more positions from that run at Bergen-Enkheim, adding 31.8 minutes to the arc for this now risk-listed object.
- March 26 #2: Discovery of small asteroid 2007 FY20 has been announced, found this morning from Arizona by the Catalina Sky Survey, which observed it in three runs. The discovery was confirmed this evening from Jurassien-Vicques, Altschwendt, and Great Shefford observatories in Switzerland, Austria, and England, and by Guidestar and Bergen-Enkheim observatories in Germany. JPL reports that this object will pass Earth at 5.3 lunar distances on April 2nd, and MPES is showing that it will go out of view for ground-based optical telescopes two days later. Update: 2006 FY20 has been listed as an impact risk.
- March 26 #1: Monday's DOU MPEC 2007-F76 reports observations of nine small asteroids, but, oddly enough, five of them come from March 11th to 15th. On those evenings Gnosca Observatory in Switzerland observed risk-listed 2007 EK and 2007 EV as well as 2007 EG, 2007 EY25, and 2007 EK26. Additional observations from within the short observing arcs of these objects are useful since they are all now out of view for most NEO observers and three of them for all observers. 2007 EG will similarly disappear in early April and 2007 EK26 in mid-April.
In more recent work, Desert Moon Observatory in New Mexico extended 2007 CQ5's observing arc from about 36 to 46 days, Reedy Creek Observatory in Australia added about eight days to 2007 EO's seven day arc, the Catalina Sky Survey in Arizona tacked about five days onto what had been 2007 EN26's eight-day arc, and Spacewatch used its 1.8-meter telescope to add about four days to 2007 EJ88's former eight-day arc.
- 2006 VV2 special report: Earth's busy neighborhood usually only has small and often unseen asteroids in close proximity. This week, however, a definitely not-small asteroid will make an unusual and rather showy close flyby. 2006 VV2 will be inside of ten lunar distances (LD) from Earth between 0100 Friday and 1100 Sunday, coming to 8.8 LD at 0548 UT on Saturday, March 31st. JPL's radar planning page says 2006 VV2's "absolute magnitude of 16.7 suggests a diameter within
a factor of two of 1.5 km." (0.9 mile), and "This is the closest approach predicted for an object this intrinsically bright until May 2036, when (66391) 1999 KW4 will approach within 6.0 lunar distances."
The JPL page tells that radar observations are scheduled at Arecibo (305-meter radio telescope) in Puerto Rico on the 31st and 1st, and at Goldstone in southern California on the 27th, 30th, and 1st through 3rd. Something not often done in recent years will be bistatic observation planned for the 30th and 1st. Instead of both transmitting and receiving radar signals, the 70-meter Goldstone telescope will transmit while ten 25-meter radio telescopes across the 5,000-mile wide Very Long Baseline Array (VLBA) do the receiving.
JPL's planning page notes that 2006 VV2 "may reach 10th magnitude at closest approach
and should be visible in small telescopes. Consequently, it's an excellent target for photometry,
spectroscopy, and infrared radiometry" (Modra Observatory is "reporting that VV2 has a rotation period of 2.43 hours"). 2006 VV2 is also providing an unusual variety and number of stellar occultation opportunities. As predicted by Derek Breit here, 2006 VV2 will briefly block the light of one to seventeen stars per day somewhere on Earth from today through April 5th, and a few more stars after that. See for, example, ground shadow tracks through England and Spain, North America, and Japan.
2006 VV2 was briefly listed last November as an impact risk. Although classified as "potentially hazardous," it is not an immediate threat for the forseeable future.

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.
