Something ASTROLOGICALLY IMPORTANT!!
Information taken from: http://www.astrowisdom.net/articles/in-search-of-best-house-system.htm The Placidus House System is undefined for latitudes above 66°33', the Arctic Circles. This means that natal charts drawn for people who were born in a certain latitude will NOT be accurate at all! If you are born at a high latitude area, you should try using the Topocentric House system instead. It is very similar to the Placidus House system but MAY result in more accurate placements for people born in high latitudes. *If you don't know what latitude you were born at you can simply google the coordinates of your country* Topocentric House Calculator: go to Astro.com Extended chart selection Scroll down, under the "House System" drop arrow you need to select "Polich-Page". *Polich-Page is another name for Topocentric House System*
