Full Moon - Harvest Moon

Full Moon over the Wolds, from High Hutton

The harvest has been in full swing for weeks now, we're officially in Autumn and the nights are drawing in. Often in September we see a fat full moon hanging on the horizon and call it a 'Harvest Moon' - but what is a Harvest Moon and why does it seem so big?

The Harvest Moon is defined as the full moon closest to the Autumn Equinox, the day when the length of day and night are equal and the sun crosses the celestial equator and heads south for the winter. This year that day is September the 22nd and the nearest full moon falls on September 30th, so the next full moon will be a Harvest Moon.

And the size? That's down to something called 'The Moon Illusion'. When the moon is seen near the horizon it often appears to be larger and closer than when it is high up in the sky. The reason is still hotly debated by psychologists; one theory suggests that when we see the moon next to recognizable objects on the horizon (houses, trees etc) we judge the size of the moon to be large and near the those objects, but when the moon is high in the sky we have nothing to compare it to and judge it to be small and distant.

But whatever the reason, get yourself outside on the evening of the 30th of September and enjoy the sight of a big and beautiful Harvest Moon rising over the Wolds.

Welcome To Autumn

Straw Bales near Low Hutton

It's here, like it or lump it, autumn has arrived. Or has it?

An astronomer would say no, autumn begins with the autumnal equinox, when the length of night and day become equal, this year that happens on the September 22nd.

The Met Office on the other hand, defines autumn to start on the 1st of September and for many people the August bank holiday marks the end of Summer.

 But you don't need a dictionary definition to tell you. The sky has turned that extra deep shade of blue, the heat of the sun is cozy rather than 'blazing June' hot, and there is a melancholy echo in the trees caused by the combine harvester chewing its way through another field of corn. The fields are full of bales, rose hips are swelling in the hedgerows and a fat moon hangs in the sky.

 It's here all right, welcome to autumn.
