No, don't panic!
This is not an advance warning of global catastrophe as the planet is consumed by a rampaging sun. Nor, and possibly this may be an even greater relief, does it have anything to do with 1970s television. Note for our younger readers: in the Seventies we'd sit glued to the TV set, possibly by the static electricity from all that damn nylon, as the Holiday programme, hosted by Cliff Michelmore, scorched across our screens to the refrain Here Comes The Sun... Ah, yes, those indeed were the days.
At this time of the year thoughts turn towards our nearest star, or more specifically towards its effects on the weather in our particular corner of the world. After the chill, grey days of winter I think that most people, even the snow-lovers and 'coldies', derive some pleasure from the increasing warmth of the sun's rays on our faces as we go about our business.
