What is the Internet Amateur Astronomers Catalog (IAAC)?
The Internet Amateur Astronomers Catalog (IAAC or 'netastrocatalog'
for short) is a forum for amateur astronomers at all levels to share
their observations of Deep-Sky objects. (The 'deep-sky' includes all
objects which are NOT members of our solar system: other galaxies,
star clusters, gaseous nebulae, doubles, and variable stars are all
deep-sky objects). Note that the netastrocatalog is a *catalog of
amateur observations*, not a sales catalog of any kind!
If you'd like to submit your OWN observation of any astronomical
object, please fill out the following Web form with your observation:
Or, if you use one of the wonderful observation-planning applications
out there, such as Jeff Bondono's
dObjects or DeepSky2000,
you may simply be able to submit your observations to the IAAC via a
menu item in your application. Ask your software author about this!
Once you submit your observation to netastrocatalog, it will appear on
the World Wide Web along with countless other amateurs' efforts,
within a week or so. In addition, all 'netastrocatalog' subscribers
will see your submission immediately! The whole (LARGE) archive of
previous logs is available at:
Or you may search for observations of a particular object at:
Finally, there is a mechanism for searching observations via
email, using the 'retrieve' command in MajorDomo. If you would like to
find out more about this, email the list administrator.
Last but not least, if you submit your logs to any of the deep-sky
observing societies, then you may simply "Cc:" your observation
posting to their respective email addresses as well! The Webb Society for instance, has
indicated that our format is acceptable to them.
NOTE: In addition to the main 'netastrocatalog' list (which is only
intended for observations by amateur astronomers), all participants
are also automatically subscribed to a mailing list for
DISCUSSIONS and ANNOUNCEMENTS relating to the IAAC, called netastrocatalog-announce. Again,
by subscribing to either of these two lists, you are actually
automatically subscribing to BOTH. Similarly, unsubscribing from
either automatically unsubscribes you from both.
