SPX vs George Bayer's Rule #6A - Declination of Mars

MARS DECLINATION HELIOCENTRIC, 19°51’00” *

From the Nautical Almanac, page 191 up we find the apparent Declination of Mars. We use in this only the value 19°51’. We locate these days ahead of time and expect tops and bottoms to appear there ... These cases happen twice or three times a year.

[George Bayer (1940): Stock and Commodity Traders´ Hand-Book of Trend Determination. Carmel, California; p. 47]

* Heliocentric declination does not exist. In astronomy the heliocentric coordinate system uses longitude and latitude; the geocentric coordinates system longitude and declination. Since Mars oscillates between latitude +/- 1.85 degrees, Bayer was actually looking for days when Mars' declination was at +/- 19°51’00” = 19.850 degrees.
