Latlong information is findable at http://jan.ucc.nau.edu/~cvm/latlon_find_location.html .
Helaical rising of Sirius calculable with code findable at http://www.culturediff.org/english/software1.htm .
Calculator doesn't seem to parse fractional degrees; this may be error in trying to remember how to do the commas and periods for European usage. Given that latitude is findable as 42 28', this is tricky; 42 gives 15 August, 43 gives 16 August for New Year's. Guesses about the altitude we're at iffy, but seeing as I'm just barely not on the coast, no major worries.
