SPENCER<br />
HOWSON<br />
Breakfast presenter<br />
612 ABC Brisbane<br />
#1 at breakfast<br />
There’s an event in 2012 Spencer Howson has<br />
had in his diary for nearly 10 years and it’s one he is<br />
definitely not going to miss<br />
We live in an era of short-term goals,<br />
from politicians always eyeing off<br />
the next poll to our general inability<br />
to plan ahead (“Where will I meet you?” “Text<br />
me when you get there”).<br />
This year, Queensland will host an event<br />
billions of years in the making. I’ve known<br />
about it – and been looking forward to it –<br />
since 2002, but astronomers have had 14<br />
November 2012 circled on their calendars for<br />
generations. I’m talking about a total eclipse<br />
of the sun.<br />
Total solar eclipses occur somewhere on<br />
earth every 18 months or so, but they’re not<br />
always easily accessible – I had to fly in a<br />
747 to see one over Antarctica in 2003 – and<br />
getting to view one from Queensland is rare.<br />
The next one is in 2037.<br />
Brisbane Planetarium curator Mark Rigby<br />
has seen seven, from Australia, PNG, the<br />
Libyan desert, Siberia, the mountains of<br />
China and remote Easter Island. “It is unlike<br />
any other experience in life. Time goes by in<br />
a flash as one senses, as does wildlife, that<br />
something unstoppable is in progress, a ballet<br />
set in motion billions of years ago,” he says.<br />
A total solar eclipse occurs when the moon<br />
blocks out the sun. Day turns to night and for<br />
the period known as “totality”, it is safe to look<br />
at the sun with the naked eye. Our nearest star<br />
appears as a golden ring (its outer atmosphere)<br />
with a deep black centre (the moon).<br />
The length of totality depends on the<br />
eclipse and your location. This November,<br />
totality will last around two minutes.<br />
Seen from Cairns, first contact (where the<br />
moon first kisses the edge of the sun) is at<br />
5.44am, totality from 6.38am to 6.40am, and<br />
second contact (where the moon leaves the<br />
sun) at 7.40am.<br />
At my first total eclipse in Ceduna, South<br />
Australia in 2002, I enjoyed a mere 32 seconds<br />
of totality but that was enough to light my<br />
eclipse evangelism! I haven’t stopped talking<br />
about them since!<br />
Mark Rigby explains his addiction: “No<br />
two are the same. I find that I am only ever<br />
absorbing part of what is going on. You are<br />
left with a thirst for more. And it’s a good<br />
excuse to see places one might not otherwise<br />
visit! The appearance of the diamond ring<br />
effect (the last vestige of sunlight piercing<br />
through a valley on the limb or edge of the<br />
moon) is amazing and then follows totality<br />
looking like a circular hole of the blackest<br />
black surrounded by the pearly corona<br />
(outer atmosphere) of the sun. Then another<br />
diamond ring and totality is over. I feel on<br />
both a high and low simultaneously – it’s over.<br />
And then people talk of the next one!”<br />
Some people say the total solar eclipse<br />
experience is like looking into the eye of God.<br />
It certainly gives you a deep connection with<br />
the universe. After all, as Rigby explains, they<br />
won’t occur forever. “The moon is drifting<br />
from the earth at 3.8cm per year. Around 600<br />

million years from now, the moon will be too<br />
distant to block out the disc of the sun – no<br />
more total solar eclipses. We are lucky!”<br />
Rigby says most people will view the eclipse<br />
from areas around Cairns, from Innisfail to<br />
Port Douglas. He says the sun will be low in<br />
the eastern sky so you’ll need a fairly flat,<br />
unobstructed eastern horizon. Find somewhere<br />
that also has a view of the west-northwest<br />
and you’ll see the moon’s dark shadow racing<br />
towards you. But, if you can’t get there yourself,<br />
Mark Rigby and I will broadcast the spectacle<br />
live during my breakfast show on 612 ABC.<br />
If you are planning a trip, consider booking<br />
a vehicle so you can get away from bad<br />
weather. That said, Mark Rigby cautions: “It is<br />
sometimes the case that people have moved<br />
and would have been better off staying put. In<br />
the end, it is probably a case of que sera sera –<br />
whatever will be, will be!”<br />
Finally, you will need special eclipse<br />
glasses or #14 welding goggles before and after<br />
totality – you are looking at the sun, after all.<br />
Just make sure you remove them as soon as<br />
totality begins, something I didn’t realise for<br />
valuable seconds in Ceduna (and which Mark<br />
Rigby has never let me forget!)<br />
