Yes, it's quite low at that time as Piers said - best to look at about midnight or later. It's really unmissable when it's up - brighter than the brightest stars and distinctly red. I think it's highest at about 2am or thereabouts, when for those of us around 50N it will be about 30 degrees above the horizon.

Actually in my first mail I was a tiny bit too pessimistic - Mars is actually 25 arcseconds in size (can't remember where I got the lower figure I quoted from). So that's as big as a pound coin at only 200m distance, and to get an image 1mm across on film you could get away with a focal length of only 9,000mm! Still a bit beyond the reach of the OM system unfortunately.

If I wanted to see Mars tonight, say at 10pm London
time (11pm here), in which direction do I have to look
for it? How high or low above the horizon should Mars
be?

Thanks for a your helpful guidance.

Thomas
