Earth's Busy Neighborhood
ACC's Small Object Report for 5-11 Dec. 2005
A semi-automated report compiled on 12 December 2005 at 0008 UTC
There are 31 small objects reported in the last 168 hours, during which 12 were newly discovered.
Currently 922 NEAs are listed with H>22.0 by JPL and/or the Minor Planet Center (755 are listed as such by both).

Editor's Dec. 7th note: The scripting that assembles all the information
you see here is far enough along, and this page is now useful enough and working
well enough, to go public in its current form. There will be additions,
such as indexing and cross-referencing, and other changes to come.
Long-time A/CC readers will recognize this page as a resumption of our
weekly small object reports published for awhile last year. This feature in its
new form is intended to update when needed as time permits on a daily basis,
and a copy will be archived off on Sundays.
Object listing order is by smallest size first, with size calculated using a
standard but very general formula based on an object's absolute magnitude (H),
or brightness. ("Small" is less than roughly 135 meters in diameter, below the
size theoretically considered to be potentially hazardous.) Observatory order
within object listings is by earliest observation during the reporting period.
Updates to this page will be flagged on A/CC's RSS news feed, and there will be
some related news reporting as time permits.

- At the end of the day, 11 Dec. UT, MPEC 2005-X65 announces the discovery of 2005 XX77 with H=23.9.
- MPEC 2005-X57 late on 10 Dec. announces the discovery of 2005 XO66 with H=24.4.
- MPEC 2005-X55 on 10 Dec. reports the recovery of 2001 YP3 with the Spacewatch 1.8m telescope on 6 and 10 Dec. This object, which the Minor Planet Center calculates at H=22.0 and rates as potentially hazardous, was previously observed from 17 Dec. 2001 until 5 April 2002.
- 2005 XN27 was delisted on the 10th as an impact risk.
- 2005 XX flew past Earth early on the 9th at 2.2 lunar distances (LD). The next known passage inside of ten LD comes on the 14th with 2005 WC1 (JPL H=20.4, ~280 meters wide) at about 7.9 LD.
- On Dec. 9th, your newest neighbor discovery is 2005 XN27, which may be a bit smaller than 50 meters wide. It flew past the Earth a few days ago at about four lunar distances. UPDATE: JPL has posted this object as a low-rated impact risk.
- Risk-listed 2005 UC3, which hadn't been reported since its Oct. 27th discovery MPEC, is in the Dec. 8th DOU MPEC as observed on Nov. 11th, increasing its observation arc from 1.925 to 18.071 days. This small object passed Earth at 13.1 lunar distances on 14 Oct. 2005, and went technically out of view for most observers on Oct. 28th.
- 2005 XA8 has been posted on 8 Dec. by JPL and NEODyS as an impact risk. This object is calculated (on 8 Dec.) to be technically in view for most observers until the 19th.
- LINEAR discovery 2005 XA8 is calculated by JPL to have flown through the Earth-Moon system on Dec. 5th at just a little more than half the distance to the Moon. At absolute magnitude H=25.5 reported by JPL on Dec. 9th, 2005 XA8 is in the top of the size range typically calculated for objects observed by telescope passing so close. However, it is less bright than the unusual closer-passing 2002 MN's H=23.2, a difference that works out very roughly to some 25-30 vs. 75-80 meters wide.
- Peter Birtwhistle has posted a detailed explanation of his part in confirming the Nov. 26th passage of tiny 2005 WN3 through the Earth-Moon system.
- Earth's newest neighbor discovery is 2005 XZ7, found on Dec. 7th by the FMO Project and announced early on the 8th.
Earlier A/CC report: The object with temporary designation SW40UJ on the Minor Planet Center NEO Confirmation Page (NEOCP) "Added Dec. 7.61 UT" is a Spacewatch 0.9m telescope discovery from FMO Project online volunteer image reviewer Kevin Fetter of Ontario, Canada.
- Australia's The Age is reporting that, in addition to Western Australia's spectacular Saturday night light show, there have been three "major" meteor sightings over Victoria Monday, Tuesday, and Wednesday nights.
