John S Mc Fall asked the Naked Scientists:

3 nights ago, the UK Media advised the public of a major phenomenon ie the Moon was passing the earth closer than for many, many years and would appear 40% larger than normal, this event would coincide with a display of meteor showers.

We live outside of Cape Town, how come we didn't see anything in the southern hemisphere and I kept going outside for a look. What is the explanation for the fact that the southern hemisphere was excluded from the event?

Very kind regards,
John Mc Fall

What do you think?

This don't look right to me. Are you sure it was the moon? I think the moon pretty well stays put in orbit and doesn't vary in distance by very much. Certainly not 40%. ??:

Okay that makes sense. It appears 40% larger because of where the full moon happens in the elliptical orbit. I wouldn't think the southern hemisphere would be excluded.

You are misquoting the size increase was 14% (not 40)and that was probably over the minimum size rather than the average.
