Denis,

That's an excellent observation from Mike.

The comet is theoretically visible from the UK if the weather cooperates
although you would need a very good western horizon.

 From my location in the south east of England the comet is 3 deg up at
17h UT, currently to the right of and below Venus.

Nick.
