 My recent return to serious AM DXing has only proven that I
 still have a 
 lot to learn.
 
 For instance, I spent the past day reading detailed reprints
 from the 
 NRC and IRCA publications involving Local Sunrise and Sunset
 DXing, 
 including a review of maps and calculations. Complicating
 the issue are 
 FCC rules changes which have changed the types of stations
 and their 
 authorizations.
 
 At the moment, I'm looking for software or a web based
 application that 
 would provide the following information without having to do
 a lot of 
 manual calculations:
 
 1.) Gray line map showing also the tilt of the earth between
 solstice 
 and equinox. In other words, a map that provides a real time
 view of the 
 earth as it really is today. Not a simplistic representation
 that does 
 not change with the seasons.
 
 2.) The ability to select any two points on earth and see if
 they are in 
 darkness or light.
 
 3.) Domestically, I'd like a map that shows which areas are
 operating 
 under sunrise or sunset authorizations. In other words, one
 that will do 
 the calculations for me.
 
 Does such a tool exist?
