If you are in the UK with access to a South Westerly CLEAR Sky then between 1630 and 1830 the sight that the three wise men are supposed to have seen 2.000 years ago will be available to you tonight although the 21st (Monday) will be the best nights view,
It is the conjunction of Jupiter and Saturn,
It will be visible to the naked (Non Cataract) eye, although a pair of binoculars or a telescope will certainly help.
Christmas Carols are not obligatory whilst viewing
