Dear Members

What sort of horoscope and house division is used for people born in Polar region or in places beyond 66 degrees N or S, as we know Placidus system collapses in these areas

Thanks

At high latitudes use the equal house or whole sign house systems. To find the cusps of the houses add thirty degrees to the ascendant degree and then the same to each cusp around the wheel. The MC degree may appear below the horizon.
 
Using Equal House is not quite the solution that it seems. In polar latitudes there will be a period every day when the Ascendant is retrograde. That means that the degrees ahead of it in the zodiac are no longer about to rise, so they cannot be in the first house. But it gets worse. If we look at Marie Peary's chart (1893.09.12 "late in the day" at 77°44′ N, 66° W), the Ascendant turned retrograde at 14 hr LST and direct at 22 hr. At each station, the Ascendant changed places with the Descendant, so the house positions of the planets all changed in both the EH and WS systems. The Sun at that date and location could only be in houses 1 to 11 and 6 to 8. But for the observer, the Sun rose, culminated, and set normally — its jump from the 11th to the 8th house didn't reflect anything that could be observed.

Thanks for this information. I cast some charts in a couple other house systems in polar regions and noted that the same thing happens in Porphyry, Alchabitius, and Krusinski. What each of these has in common with EQ and WS is that they base the house construction on the rising degree in some way. I noted that Placidus, Regiomontanus, Campanus, and Polich-Page don't have this quirk since they use the entire horizon to identify where the first house begins, rather than calculate the first house from the rising degree. Of course, these all have the problems that arise when the MC and the ASC are extremely close together.

Perhaps the best method is to erect a chart using direct visual observation, as they did throughout the world thousands of years ago…
