Comment:

 Hi,

 I can reproduce with the 6.4.0~rc6+42329-3 (essentially 6.4.0)
 Debian/stable package on amd64.

 the problem is due to the lat= option.

 note in grass65+trunk I've removed it (2 years ago) due to incompatibility
 with rsunlib, but in practice it was not much help anyway.
 {{{
 GRASS65> r.sun --help
 ...
      lat   This does nothing. It is retained for backwards compatibility
 }}}


 see https://trac.osgeo.org/grass/ticket/498#comment:14

 I think the bug here is that I never backported the fix to the relbr64.

 ps- see also in #498 comment 8+ (and attachment image) and maybe the r.sun
 wiki page about the difference that slopein= and aspin= maps make, in fact
 they ruin the result! until that is fixed, you get better output if you
 just leave those two options out and let the slope/aspect calculations
 happen as the module runs.
