This week Christopher Ciccone published his memoir 'Life With My Sister Madonna', so here's his birth chart.

The Sun changed Signs at 2:18am local time on the day he was born, and since we have no time of birth for him we can't calculate which Sun Sign he has: it could be Scorpio, or it could be Sagittarius.

I'll leave interpretation until another time and for now just present Christopher's chart wheel.
