Hello everybody
Suppose a horizontal sundial at latitude 4º S. His gnomom is a very
acute
square triangle. What happens with the shadow when sun's declination get the
other side of celestial equator? What happens at the july solstice, does
the shadow
make redable, correct indication?
Thanks in advance
