Spring Equinox Leeds Photos and Ancient Astronomy Update

Earlier in the month I posted about using buildings on the Leeds skyline to show how the sunrise can be seen seeming to move northwards after the Winter Solstice in the northern hemisphere; perhaps like ancient astronomers did at henges around the world.

The sunrise is apparently really about our axis tilt and orbit around the sun. We are seeing it earlier now in the north because our half of the planet is pointed towards the sun. The tilt stays the same all year around; unlike a motorbike racer going around a circuit, always keeping their head leaning inwards at corners.

Last time I wrote how the sun had moved from south of two iconic buildings to the centre of them over the course of five days, and the sunrise was ten minutes earlier: from 6.51 to 6.41.

2nd March, sunrise at 6.51

6th March, sunrise at 6.41:

Now, a fortnight later, on the spring equinox, the ‘sunrise’ has moved much farther north on the horizon, with those two buildings now towards the far right of today’s photo. The sunrise is also thirty-four minutes earlier at 6.07:

20th March, sunrise at 6.07:

I took lots more photos this morning and will post them soon. It’s been a long day! Great in the sky, but difficult on Earth (in the news!).
