Mars now is an impressive view in a good telescope. But it amazes me to read that the closest approach of mars to earth was on october 29.
I read many other sources which claim that the closest approach is on November 7, and that latter date complies with what my astronomical simulation programs tell me.

On the possible quality of observations of mars, this difference in dates has no effect. But what causes this difference? Does anyone have a cue?
