> NOTICE CONCERNING FAINT POSSIBLE SUPERNOVAE
> Extensive discussions between the Central Bureau and supernova
> observers in the last couple of years -- largely regarding the
> problem of very faint, spectroscopically unconfirmed supernova
> suspects -- culminated in the decision, made at the meeting of the
> IAU Working Group on Supernovae (WGS) at the IAU General Assembly
> in Sydney last July, to establish an interactive webpage (cohosted
> by the CBAT and WGS) that will allow registered users to post
> discovery observations immediately under a provisional-designation
> scheme so that the entire community can have ready access to them
> in helping to confirm them as supernovae. The interactive webpage
> is still under construction, but with observers' eagerness to get
> their data announced quickly, the Central Bureau has established a
> preliminary, noninteractive site at URL
> http://cfa-www.harvard.edu/iau/CBAT_PSN.html. Contributors are
> asked to read the instructions at that website and submit data in
> the standard format described therein. Objects listed at this
> website will have provisional designations tied in to the date of
> discovery; any objects later confirmed as supernovae will receive
> formal supernova designations and be announced, as usual, on these
> Circulars.
