In case you haven't already found out, there will be a lunar eclipse tonight. It should be readily visible from Europe, the Middle East, Africa, South America and much of North America. The first contact with the Earth's shadow is at 00:11 UTC, maximum eclipse at 02:47 UTC, and last contact at 05:22 UTC. Currently the Central European Timezone is 2 hours ahead of UTC; the UK is one hour ahead; the US Eastern Timezone is 4 hours behind.
This eclipse is also notable for coinciding with a "super-moon", i.e. the Moon is a bit closer than usual. This means that it will appear a bit bigger, and (more important for observers) the eclipse will last longer and the Moon will be darker.
For those wanting more information, there is, as ever, a
BBC News article, and also the
NASA Eclipse Website (from which the BBC seems to have got most of its technical information).
