The view from New Zealand
The full Moon will enter the Earth's penumbral (partial) shadow shortly before 8 pm. At this stage there will be no obvious change to the Moon, although careful observation over the next hour will show the Moon's light is getting a little less intense as it moves further into the penumbra. It may also be noticed that a few more stars are becoming visible.
Just before 9 pm the Moon will start moving into the Earth's umbral (full) shadow. The first contact with the dark shadow will be on the northeast edge of the Moon, but at this stage for NZ viewers the Moon will be well round towards the east and rotated so that the shadow appears at the bottom of the Moon. Over the next hour the shadow will move up the Moon which will become a very dull and possibly coppery colour. As the Moon loses brightness so more and more stars will appear.
Totality will last for about 90 minutes, from 9:52 pm to 11:22 pm. The northern part of the Moon, the lower part as seen from New Zealand, will pass through the centre of the Earth's shadow and is likely to be darker than the upper, southerly, parts which will be nearer edge of the shadow. The Moon will still be visible due to refraction of light through the Earth's atmosphere onto the Moon. Because the atmosphere absorbs more of the blue light, the Moon is likely to appear reddish, just as the sky to the west appears orange near sunset.
By the end of totality the Moon will have moved quite a way round to the north, so that its north pole is now almost at the bottom as seen from New Zealand. Just after 11:20 the first part of the Moon will re-enter the Earth's penumbra. This will appear on the right hand side of the Moon a little below centre. Over the next hour the brightness will spread across the Moon, with the last of the dark umbral shadow disappearing on the left hand side, just above centre. This will occur just after 12:20 am in New Zealand when the Moon will be almost due north and at its highest.
