Q1: How do we know on which hemisphere we are?

55.37 N is North hemisphere cos after the 55.33 is N if was S u where in the south hemisphere also if u are above equator u are in the north hemisphere if u are below equator u are in the South hemisphere

Q2: Where did you get that 20 LHA for longitude??

that come automatic from that spreadsheet file it's calculate it alone.... u need to use that file or a Almanac to find the declination, index error, LHA, without a almanac the calculation is incorrect

I just dont get it, there's no explanation, just open excel, there is 20 LHA.. i mean what?
It seems to me like i have to watch sun vertical angle periodically and when i find its on zenit, get the time..
Then somehow calculate longitude by substituing difference of sun zenit time from GMT noon and dividing somehow, but its not described here..

I dont want to use some scripted xls, i want to know how can i get LHA.

go here for online almanac to calculate your position.....
local noon is described in post #1.

PS. u can use also Stellarium a great software
