The times are incorrect for those on daylight savings (eg Melbourne).
They should be 1 hour later. Eg, Melbourne is 18.35.
>Remember, DO NOT look directly at the sun during an eclipse.
If you have full-strength welders mask/goggles, you can look at the Sun
safely directly through those.
Otherwise, get 2 bits of white card, cut a hole a couple of millimetres
across in one of the bits, and project the Sun through this hole on to
the second.
I'll be projecting it through my binoculars (as my telescope won't be
available at the time).
(For those interested, the next total solar eclipse in Australia will be
in the Adelaide region in 2002)
