1) With a bright core (located at the following end of what became a long, complex, bright region with several secondary spots) at saturnicentric
latitude +34[degrees], its positive drift in System III longitude of +2.
I have defined b as the square root of the absolute value of the product of the Saturnicentric latitude of the Earth and of the Sun; b is a latitude that is always within about 27[degrees] of Saturn's equator.
During this study, the value of B', the Saturnicentric latitude of the Sun referred to the plane of the rings, went from 0[degrees] in 1995 to 27[degrees] in 2002 and back down to 0[degrees] in 2009.
The quantity b ("a type of geometric average of Saturnicentric latitude of Sun and Earth from Saturn's ring plane") is computed from equation (1):
In this equation B is the Saturnicentric latitude of the Earth referred to the plane of the rings and B' is the Saturnicentric latitude of the Sun referred to the plane of the rings.
Four different methods were used in measuring the Saturnicentric latitudes which are: visual, reticle, photograph and video measurements.
Summary of Saturnicentric latitudes of various features on Saturn.
The Saturnicentric latitude of the Earth (B)= the Saturnicentric latitude of the Sun (B').
The Saturnicentric right ascensions of the Sun and Earth should be equal.
An average value, along with the standard deviation of the measurements, was used in computing Saturnicentric latitudes (Alexander, 1980).
These data have been used to produce a map of Saturn and define the approximate Saturnicentric latitudes of the two principal belts on that planet.
declinations of Earth and Sun, and hence the tilts of the ring as seen from the Earth and the Sun would be different even if the plane of Saturn's orbit did coincide with the ecliptic.
