Yup, Blitz, sorry, that's exactly what I mean. A heliocentric theory correctly predicts the phases as observed.

Observations that the Ptolemaic system would not allow.

I was, by the way, amazed that a phone camera could show this, but apparently people with really keen eyesight can see the phases with the naked eye!

I've still got the shot I took from my own phone on that day. It still never ceases to amaze me and I take every opportunity to show it to all and sundry.

I got up at 5am for the transit but it was overcast here in northern England - doh!
