Supernovae

A list of recent supernovae is available, as is our on-line form for checking possible supernova candidates.

The best guide for ephemerides for forthcoming periodic comet returns is the annual ICQ Comet Handbook. Predicted elements for returns up to three years into the future are published in the Minor Planet Circulars. Ephemerides for all currently-observable comets may be generated in the CBAT/MPC Computer Service.

Advantages Of Subscribing

The main advantage of having your own personal subscription to the IAUCs and/or MPECs is obvious: you would no longer have to rely on second- or third-hand sources for information on new astronomical discoveries. A less obvious advantage is that the more subscribers we have, the less we have to charge per subscription to cover our costs. We are a non-profit organization--if we increase our subscriber base significantly, we can reduce the subscription rates by substantial amounts.

A look at the Recent News above shows you what you have been missing by not subscribing. The uninvoiced e-mail delivery of both IAUCs and MPECs, via a subscription to our Computer Service, is currently only US$6 per month--a real bargain!

Check out the condensed subscription information, as well as details on payments by credit card. Full details on how to subscribe are also available.
