IAUCs & MPECs on the Web
As an experiment, announced at the 1997 IAU General Assembly in Kyoto, the IAUCs and MPECs may now be read freely on the CBAT/MPC website. NOTE: Due to the much reduced income from subscriptions over the past few years, this experiment was terminated on 2004 Nov. 9: IAUCs are now restricted to subscribers only.Ensure that you have read these notes on the conditions under which circulars are made available on our WWW site. Note in particular that circulars are not to be redistributed--this restriction includes, but is not limited to, posting on other websites or USENET newsgroups, or included on CD-ROMs.
Note that newly-issued IAUCs may be subject to a delay before being posted on the Web. If you have a need for immediate, passive delivery of circulars, you must continue to have a subscription.
How Do I Access The Circulars?
Follow this link to the search facilities, this link to the titles from the 20 most-recent IAUCs or this link to the titles from the 20 most-recent MPECs.Access to the circulars is also possible by following the links from the lists of recent and all supernovae, and from the links on the Astronomical Headlines page.
About the HTML versions of the circulars
It is important to remember that the printed version of the IAUC remains the official version. Where the printed version differs from either the e-mail or HTML version it is the printed version that takes precedence. Since there is no printed version of the MPECs, the e-mail version takes precedence over the HTML version.
Each IAUC or MPEC is available in an HTML conversion of the
plain ASCII version of the circular; recent IAUCs are also available in
.dvi and .ps formats. The HTML conversions
include:
- making references to IAUCs and MPECs into HTML links
- making imbedded URLs into HTML links
- making Internet-style e-mail addresses into
mailtolinks - use of bold characters for titles and footers
- easy access to previous and next IAUC or MPEC, as well as to IAUC search facilities
What circulars are available?
All MPECs are available.All IAUCs from number 2700 (issued 1974 Sept. 20) to the present are available, as well as a handful--currently 220 (8.1 percent) as of 1998 Jan. 17--of earlier circulars, including number 1 (issued 1922 Oct. 22)! Work is progressing (slowly!) on getting these missing IAUCs in electronic form and putting them on-line.
