Hi, In the US, you sometimes get an "Indian Summer" around this time of year. So do we in Australia. That's strange because the seasons here are reversed. IOW it happens to the whole planet at the same time of year. What happens on an annual basis? We go around the Sun. So maybe there is a particular spot on the Sun that radiates more than elsewhere, and we just go past it around this time of year?
