By Jove I can see Uranus
At the top is Jupiter with three of it's moons. Left to right they are Eurpoa, Io and Ganymede. At the bottom is Uranus which is 2.9 billion kilometres away (it takes light over 2 ½ hours to reach earth). I could see Jupiter clearly with the naked eye and the moons with binoculars but I needed the camera to see Uranus. I used a 3 second exposure.

Wobbly
Bridge
This foot bridge across the Avon has been badly twisted. The bridge has barriers across it to stop people walking on it. They don't seem very effective as we saw several people risking it. I reckon this will be a magnet to young kids. Imagine taking a skate board across that. To be honest if Tracy and James weren't with me I would have had a run across.

Chip Shop on Barbadoes St
The aftershocks have become so commonplace that people are now playing a game. After a shock comes through everyone guesses at the magnitude. About 10 minutes later the report appears on GeoNet. Closest to the actual magnitude wins. I first noticed Tracy and Sandra playing this at home but it seems to have spread through every office in Christchurch.
Fortunately, the frequency and size of the aftershocks does seem to be decreasing and life is returning to normal. Our water no longer needs boiling and the cordon around the city centre was relaxed today.

More aftershocks.
Last night there were several large aftershocks and this morning we were shook by a big one. It was only 5.1 but was very shallow and made the whole city shake. Tracy was going to return to work but the polytech needs to be reassessed after this latest quake.
There is a great map of the quake and the aftershocks at http://www.christchurchquakemap.co.nz

Update
The city centre is under a state of emergency and only authorised people are allowed in. Some suburbs have been hit very hard and I know several people who have lost their homes. It is estimated that up to 20% of houses will have to be rebuilt.
In our area things are getting back to normal. The shops are open though the corner shops in the picture below had to be demolished. Power and water are back but we still have to boil drinking water for three minutes. I am back at work and Tracy should be going in tomorrow.There have been over 100 aftershocks since the big quake and this has people a bit jumpy. I am very tired from being woken repeatedly during the night. Some of the older buildings in the city centre have been further damaged by the aftershocks and will have to be demolished.
Everyone is amazed that no one was killed. The earthquake in Haiti earlier this year was smaller than the one we experienced and over 100,000 people were killed. We were lucky, the quake struck early in the morning when most people where in bed. If it had happened during the day many people in the city centre would have been killed by falling debris. The other thing that saved us was our low density wooden homes.
James has been brilliant during this, he now knows all about how earthquakes happen and will explain it to anyone who will listen. Aftershocks don't bother him, if he even mentions them at all it is to say 'That was a big one, eh!
