ville on the northeastern coast; crosses the
Pacific Ocean, and Guadaleanal and San
Cristobal in the Solomon Islands. The path
comes to an end as the sun is setting, at
about ten degrees south and 16s degrees
west, which'is in the southwestern Pacific
Ocean.
The eclipse will be at its maximum where
the path crosses northern Australia; there
the annulus will be visible for seven min-
utes 26 seconds.
Over a much larger area, including the
rest of Australia, New Zealand, part of
Antarctica, Borneo, the Celebes and New
Guinea, there will be a partial eclipse.
In this region the moon will partially cover
the sun, with a larger portion hidden the
nearcr the place is to the path of the
anmular eclipse.
A curious feature of this cclipse is that
it ends the day before it starts!
This is because, in progressing from west
to east, it crosses the International Date
Line, at 1s0 degrees longitude, the place -
where the day changes. In the Indian
Ocean, as in Australia, it will be Wednes-
day, April 8. But after it crosses the Date
Line, which it does in the late afternoon,
it will be in a region of the earth where it will be in a region of the carth where
it is still Tuesday, April 7.
Few Eclipse Observations
Although astronomers often travel long
distances to observe eclipses of the sun,
as they did last October to Danger Island,
also in the South Pacific, where a total
eclipse was to be visible, few if any will
make much effort to observe the Australian make much effort to observe the Australian
eclipse.
Most of the observations made by eclipse
expeditions require that the sun be com-
- pletely covered. Even the narrow ring of
the solar dise left visible at an annular
eclipse prevents such work. However, it
is likely that many amateur astronomers,
and even some professionals, who are lo-
cated near the path of visibility, will take
advantage of their opportunity to see a
rare and interesting phenomenon, even .
though it is of relatively little scientific
value.
