[GRASS-user] error in r.sun with latin and longin maps

[tigrida]

Hi all

I want to create a map  with r.sun  but I get the following error:

Mode 1: instantaneous solar incidence angle & irradiance using a set local
time

pj_transform() failed: latitude or longitude exceeded limits

my  instruction is:
 
r.sun -s elevin=dem aspin=aspecto.allen slopein=pendiente lin=3.0
albedo=albedo_178  latin=latitud longin=longitud
beam_rad=beam_inst_pixel_178 diff_rad=diffuse_inst_pixel_178
refl_rad=reflected_inst_pixel_178 day=178 step=0.5 declin=0.406818033
time=11.11667 dist=1.0 numpartitions=1 

r.info latitud:
