Transit of Venus today, which I've been waiting for since about 1978. Duly observed with eclipse viewer from five years ago. Venus moved across the lower part of the Sun from left to right, from about 7 o'clock at 0700 to about 5 o'clock at 1100. It was quite clearly a disc, a small black circle perhaps of the proportion of a pea to a dinner plate or a marble to a dustbin lid. (That clears up my 'should Venus be visible as a disc') question. I let C. and D. at work have a look through my viewer.

Oddly the disc thing brought home how far away Venus is. If you know it's 8,000 miles across but it looks like a tiny circle, it must be really far away. Things that just appear as points don't give the same impression.
