At certain dates/times the filling of terminators fails. Modified pssolar example, "(46) Day-light terminators and other sunlight parameters", included.

The time difference between the two plots is one hour (2017-09-26T11:40:58 vs. 2017-09-26T12:40:58).

Tomorrow, on Jan 10th, the sun rises for the first time since early December in Harstad, Norway. See strange Sunrise/Sunset report for Jan 9th (i.e. Sun never comes up)

OK, it now prints

Since you seam to be at "Harstad, Norway" wait another day before you can see the Sun

Should be fixed. The terminator touched the north pole but did not get further south than -88 or so. Still, gmtlib_determine_pole determined it enclosed the S pole. Curiously, if you dump the path to file and plot with psxy it does the right thing. I added some more checking in the case a pole is touched and now it works. In r20187.
