Does anyone know the scientific term for the path of the Sun as it travels toward the horizon or away from the horizon without crossing it? We no longer have sunset and sunrise.
 
We have hours of dusk and dawn but it isn't easy to distinguish when one turns into the other. These are getting shorter as we head south faster than the Sun appears to be retreating as Earth moves toward a Northern Hemisphere Summer.
 
A month from when we are still down here it should start getting colder. On our return trip North the darkness should greet us much farther south than where we left it.
