Not quite total eclipse of the sun

November 14, 2012

Is it my imagination or has the temperature just dropped as the moon getting between the earth and sun gives us a partial eclipse of the sun?

This is another eclipse with a path mainly over ocean, in this case the south Pacific. The path of totality does start over extreme northern Australia about 200 km east of Darwin. The path crosses the Gulf of Carpentaria and then the base of the Cape York Peninsula with Cairns and Port Douglas seeing a total eclipse.

At Cairns the eclipse will occur in the early morning, totality lasting for 2 minutes. The Sun will be 14° above the horizon, so low to the east.

From Cairns the total path moves, at first, to the east-southeast across the Pacific, passing a little to the north of New Zealand. After reaching the latitude of the South Island of New Zealand, far out in the Pacific the path starts to swing back to the north, with the eclipse ending at sunset some way to the west of Coquimbo in Chile.

A partial eclipse will be visible from all parts of Australia (anywhere it is not total), although the Sun rises after the start of the partial eclipse for the western half of the country. A partial eclipse is also visible from New Zealand, many of the south Pacific islands and, at sun set in most of Chile and the southern parts of Argentina.

 


Pretty late

April 3, 2009

It’s pretty, but at 7.40am it’s an hour later than I’d like it to be:

march-09-001

Like Somethingshouldgohere I’m not enjoying the extended daylight savings because the extra hour of light in the evening doesn’t compensate for the cold and dark in the morning.

We don’t really need daylight saving in the south because of extended summer twilights. Although having daylight until 10ish in mid summer has its good points and I accept that in the north where it gets darker earlier in summer the extra hour of light makes a positive difference.

But by autumn I’d rather have an earlier sunrise than a late sunset. By now the extra hour of light in the evening comes over the dinner hour when I’m unlikely to be outside to enjoy it so Sunday’s reversion to standard time can’t come soon enough.

The Herald asked readers if daylight saving has gone on too long and got a range of views.

For the record, tables from the Royal Astronomical Society of NZ show sunrise and sun set times for the year:
