Both seem to be right.
I checked that one with Guide 7,
Planets on full precision. Strange thing! When starting on 1977-Jan-1 and
letting
find Guide an eclipse, it did not find any, but a conjunction in 21st
January 1977. When starting after that day
Guide actually finds an eclipse. Cape town
is in the area of occultation, whereas Perth
is a bit outside and India is far
outside the eclipse area. Are you sure that people observed and these sites the occultation
by the planet and not only
by its rings?
Hartwig Luethen
It is sure. The occultation was also
observed by a plane which followed the shade zone at 9,000 meters of
altitude. In this opportunity also the the Uranus rings was
discoverd.
