Update (11.36 pm 10 December 2011): I managed to just get a photo of the partially eclipsed Moon through a small gap in the cloud. Not particularly clear and out of focus.

Very rough and ready image of the Moon taken at 11.14 pm AEST 10 December 2011 of partially eclipsed Moon.

The last total lunar eclipse for 2011 will occur this coming weekend (10 & 11 December 2011). Simply look above the Northern horizon at the times indicated below to locate the eclipsed Moon.

Note that three different times are listed for each stage of the eclipse. The first is Australian Eastern Standard Time, the second is Australian Eastern Daylight Time and the final time is what is known as Universal Time. Astronomers use this as their ‘standard’ time and convert this to their local time zone. Queensland (and the rest of Eastern Australia when daylight savings is not in effect) astronomers for instance would add ten hours to a time listed in Universal Time.

At the time of updating this blog (10.49 pm AEST 10 December 2011), it is cloudy at my location, and I suspect most of Eastern Australia is clouded out too. One suggestion is to watch the eclipse on-line courtesy of the SLOOH website.
