Lunar eclipse tonight?
For the astronomers here: I think there's supposed to be one here in Portugal, don't know if it also covers UK - if you know what I mean . Starts at 23.30 and goes on til about 4am, IIRC (glimpsed a local paper today).

On 28 October, the Moon will appear high in the south at the start of the eclipse. The Moon will enter the lighter, penumbral shadow of the Earth at 01.05 BST and the darker umbral shadow at 02.14 BST. It will be completely immersed in the Earth’s shadow (totally eclipsed) by 03.23 BST.
During the total eclipse the Moon will darken considerably but will still be one of the brightest objects in the sky. It will probably take on a beautiful brick-red hue as a result of light from the Sun being refracted onto the lunar surface by the Earth’s atmosphere.
At 04.44 BST totality will end as the Moon begins to emerge from the Earth’s umbral shadow and then appears to brighten steadily. By 05.53 BST it will have left the darkest shadow completely but keen-eyed observers may still see a yellow hue on the lunar surface – At 07.03 BST the eclipse finally ends with the Moon low on the western horizon.

Interestingly the effect that makes the sky blue, Raleigh scattering, is what also makes the moon go red during an eclipse. The light coming from the sun hits the earths atmosphere and the blue stuff gets bounced around in the atmosphere while the red stuff goes right through and on to light up the moon.
The way that blue light gets bounced around in the atmosphere is similar to the way management bounce blame around in an organisation. The high frequency blame rays get bounced around in management hitting off powerpoint presentations, Gantt charts and the like until they are forced down on us poor workers, almost every bad ray that comes in is somehow my fault. The much less frequent good work and praise rays pass right through us lowly workers to illuminate managers at a much higher level. Praise rays never make it down to us plebs at the lower levels and so we are stuck with being battered by blame rays.
Amazing how a red moon can be explained by such things.

Not 'just' a Lunar eclipse but soon after a mathamatical astrological event called a Grand Quantile alignment as the sky is divided into fifths by the quintile angles it creates or in musical terms a Harmonic Concordance will be played in the skys. Where the Moon along with Saturn, Jupiter, Uranus and Pluto forms a Pentagram. This indeed is a very special night if you are into such things..
