Just in case you haven't read the Feb 07 Astronomy Now magazine from cover to cover yet, I thought I'd post this interesting link provided in the Letters section:
This shows visual (and infra-red is available) satellite images for the day of cloud cover surrounding the UK. It's pretty good and could be useful in looking ahead for the evening to see what's "coming your way" for the next few hours.
Fingers crossed for this weekend...although the forecast for Fri & Sat is awful. Anyone interested in trying Sunday night if it's clear?
