The Great Australian Eclipse – Diamond Ring #1


The last bit of the Sun shines from behind the ragged edge of the Moon as the total eclipse begins in Australia.

This is “second contact,” and the first diamond ring effect that heralds the start of totality. The Moon (the dark disk) is just about to completely cover the Sun. You can see the pink chromosphere layer of the Sun’s surface and a flame-like prominence at 4 o’clock position. The Sun’s atmosphere, the corona, is just beginning to show.

I took this November 14, 2012 from a site near Lakeland Downs, Queensland, Australia. While we did look through some thin cirrus clouds, they didn’t hamper viewing at all, and were not the concern that the thicker clouds were at other sites, especially at the beaches.

The Great Australian Eclipse – Success!


It wouldn’t be an eclipse without a chase. But in the end we had a nearly perfect and cloudless view of the entire eclipse — the Great Australian Eclipse. We were ecstatic!

This collage of wide-angle shots shows the motion of the Moon’s conical shadow. At top, you can see the bottom edge of the shadow just touching the Sun. This was second contact and the diamond ring that begins totality. The middle frame was taken near mid-eclipse and shows the bright horizon beyond the Moon’s shadow. However, the Sun is not centred on the shadow because we ended up well north of the centreline, sacrificing as much as 30+ seconds of totality to get assured clear skies. The bottom frame was taken at the end of totality as the first bit of sunlight bursts out from behind the Moon at third contact and the final diamond ring. Notice the Sun sitting at the well-defined left edge of the Moon’s shadow. The shadow moved off to the right.

Why did we end up off-centre? Clouds! The day before, at our 11 am weather briefing meeting, we decided not to stay on the beach but to move inland to one of the sites we selected from the previous day’s reconnaissance. The forecast was not even accurately “predicting” the current conditions at the time, saying the sky should then have been clear. It was raining. We did not trust the predictions that skies would clear by eclipse time on Wednesday morning.

We drove inland on Tuesday afternoon, getting to our choice site at the James Earl Lookout on the Development Road about 4 pm, to avoid driving in the dark and to get there before the parking area filled up. It was a good plan. We arrived to find a few people there but with room for all our cars filled with 20+ Canadians. We staked our ground with tripods, did a little stargazing after dark, then settled in to spend the night in our cars.

At dawn we got everything ready to go, only to see puffs of orographic clouds forming over the hills in the direction of the Sun. I did not like it. So with an hour to go before totality we packed up and moved down onto the plains away from the hills to a site near Lakeland Downs, the site you see here. Apart from some high cirrus clouds, skies were superb.

As it turned out, folks a few miles away at the Lookout did see it, but by the skin of their teeth. Clouds obscured the Sun just before and just after totality. That’s too nerve-wracking for me. And from the beaches, some people were clouded out, others saw all of totality, others saw just a portion of the main event. It was hit and miss. From home at Oak Beach we might have seen it but only just. We were very happy with our decisions to move and flexibility to be able to do so.

I’ll post some close-up shots of the eclipse shortly.

Tonight, we party!
