Great Shefford Observatory Minor Planet Discovery Circumstances

Ephemerides for the unnumbered objects on this page can be generated here.

As of March 2022 the number of minor planets officially credited with being discovered from Great Shefford is 106, see the list of numbered objects below.

On 19 October 2010 the Minor Planet Center published an Editorial Notice announcing a change to the way discovery credit is assigned to new discoveries.

The new rules make it more difficult for amateurs to be credited with new discoveries and also more difficult to predict which objects that are initially picked up as potentially new objects will eventually result in discovery credit being assigned to the observer.

The new rules can seem confusing at first and an article attempting to describe them can be found here.

Potential new minor planets picked up from Great Shefford are now separated into several different lists, depending on their status:

Numbered minor planets discovered from Great Shefford (and discovery circumstances summary)
Probable candidates for discovery credit (old rules)
Possible candidates for discovery credit (new rules)

The list of non-principal designations no longer has any relevance with the introduction of the new discovery rules and will no longer be rigorously maintained.

In the list below, the first column (Disc. Seq.) gives a running tally of numbered objects together with the sequence in which the objects were first picked up, e.g. 1/6 for (128465) 2004 OJ9 indicates it was the first minor planet to receive a permanent number, but was the 6th to be discovered from Great Shefford.

16/95 (210426) 2008 AV72 2008 Jan 07 +20.8 In field of MBA discovery 2007 XS16. Submitted to the MPC on 17 Jan as a ONS after poor weather stopped follow-up, but it was matched with positions from Mt. Lemmon from 12 Jan and given designation 2008 AV72. This allowed faint pre-discovery images to be identified on images from Great Shefford taken on 29 Dec for 2007 XS16 and on 19 Dec for 2007 YL2. By 21 Jan the MPC had matched it with various one and two night observations over 5 oppositions back to 2000. It had previously received designations 2000 JF4 and 2006 PH11 from observations on two nearby nights in those years, but retained 2008 AV72 as the principal designation. 2008 AV72 received permanent number (210426) in March 2009. 2009 Mar 11

Probable candidates for discovery credit (old rules)

In the list below, the first column (Disc. Seq.) gives the sequence in which the objects were first picked up, e.g. 2005 UZ6 was the 31st potentially new minor planet picked up from Great Shefford.

List of provisional designations assigned to Great Shefford that had multiple-opposition orbits as of 19 Oct 2010 (and are likely but not certain to be assigned discovery credit):
Disc. Seq. Designation Discovery Date Mag.(1) Circumstances
92 2007 YL2 2007 Dec 16 +20.1 In field of MBA discovery 2007 XS16
127 2009 CL6 = 2011 UK42 2009 Feb 14 +20.9 In search field for MBA discovery 2009 CA45.

Possible candidates for discovery credit (new rules)

Provisional designations with single-opposition orbits as of 19 Oct 2010, or minor planets that have been submitted to the Minor Planet Center (MPC) as potentially new discoveries since 19 Oct 2010. All these objects are subject to the new rules as published by the MPC in the Editorial Notice in MPEC 2010-U20.

Discovery credit for these objects will only get assigned to Great Shefford if the earliest submitted observations used in the orbital computation at the time of numbering are attributable to Great Shefford.

As at 03 January 2020, objects marked in green appear to be favourable, though it is quite likely that earlier observations from other observatories will eventually be identified when further (newer) observations come to light, extending the orbital arc. In that case, discovery credit would then be assigned to the observatory that first submitted positions used in the final orbit.

Objects marked in red are very unlikely to result in discovery credit being assigned to Great Shefford, with observations from other observatories from earlier dates already being available. However, for a few (generally marked with a ?) there is a small chance that discovery credit could be assigned to Great Shefford (if the Great Shefford observations were submitted to the MPC earlier than other observatories). Until the objects are finally numbered this will not be known for sure.


In the list below, the first column (Disc. Seq.) gives the sequence in which the objects were first picked up, e.g. 2004 PN2 was the 7th potentially new minor planet picked up from Great Shefford.

List of objects where there is a (probably small) possibility under the new rules that discovery credit might be assigned to Great Shefford:
