also the Shower Calendars of IMO include star maps that show the position
of the radiant for different dates. So, Cathy, you only need to have a
look at the printed version of the '98 calendar which was shipped with the
last WGN issue, or have a look at the WWW edition at
http://www.imo.net/calendar/cal98.html (and don't forget to enable
your browser to 'auto load images' :-)
BTW, instruction of how to order IMO publications (like the Visual
Handbook for $20) is also available in the web at http://www.imo.net/books.html.
