"How to see the lunar eclipse in the UK"
"On 21 January 2019 a total lunar eclipse will be visible over most of North America, South America and parts of west and north Europe. The rest of Europe and Africa can witness the end of the eclipse.
Those in the UK will be able to see every part of the eclipse as long as they are willing to stay up all night! The Moon will start to enter the Earth’s shadow just after 2:30am GMT and the maximum eclipse will occur just before 5:15am. The entire eclipse lasts for more than five hours, ending at 7:48am.
The optimal viewing time to see the eclipse is between 4:41am – 5:43am. This is the period of totality, where the moon lies entirely in the Earth’s umbra (full shadow) and will appear red."
Likewise. Not being well I was up most of the night - beautiful clear night, amazingly big bright moon until about 4:30 when it turned to a hazy glow behind the clouds rolling in, then it started snowing - no moon!
I set the alarm twice during the night- I got up when it was supposed to start and it looked a bit like a crescent moon, but by the time of the full eclipse an hour or so later the sky had completely clouded over.
