The WGSBN is a Working Group (WG) of the

is a functional WG, which means that it exists beyond the regular
three-year lifespan of IAU WGs.
News
The six most recent news items are listed below. The complete archive of news items is
here.
September 28: Some Updated Historical Corrigenda Files
Five historical corrigenda files have been replaced, either fixing some minor formatting issues with the references or adding missing references. No changes were made to the citation data, the modified names data or the modified discovery circumstances in those corrigenda files.
Thanks to N. Casale (Minor Planet Center) for alerting us to these inconsistencies. Most of the issues were from volumes 1 and 3, and the processing code had already been fixed to prevent these problems occurring in the future. Some further formatting checks are being incorporated into the publication process to prevent the other issues from reoccurring.
September 28: WGSBN Bulletin 6, #16 Issued
WGSBN Bulletin 6, #16 has been
issued, containing new names for 47 minor planets.
IMPORTANT NOTE @ 20:50 UTC: Do not download the data files associated with this batch! The first name in this batch is missing from the data files. We are investigating. More details shortly.
MORE IMPORTANT NOTE @ 21:08 UTC: The problem only affected the name/citation files. They have been replaced. It is now safe to download the data.
September 7: WGSBN Bulletin 6, #15 Issued
WGSBN Bulletin 6, #15 has been
issued, containing new names for 65 minor planets.
August 21: Unplanned Outage of WGSBN Server
Sometime after 12:07 UTC this morning, the WGSBN website server froze. A support call with the hosting company was immediately initiated. The website came back on-line at about 14:02:30 UTC. About 17 minutes later, the server was again rebooted by the hosting company support team. We do not yet have an "all clear" message from the hosting company. Until such time as that message is sent, be aware that the system could be rebooted at any time by the hosting company.
16:16 UTC: Another support call indicates the issue (as yet unspecified) has been resolved. Although we are still awaiting a formal message from Escalated Support, we believe the system is now stable.
August 17: WGSBN Bulletin 6, #14 Issued
WGSBN Bulletin 6, #14 has been
issued, containing new names for 29 minor planets.
August 3: WGSBN Bulletin 6, #13 Issued
WGSBN Bulletin 6, #13 has been
issued, containing new names for 8 minor planets.
