Good point. I'm just....

An interesting article from the BBC

"Why do mornings still get darker after the winter solstice?"

'Round here the day length is increased by one (1)second for today December 22; one my only hope for improvement, eh?

Indeed, the cycle of seasons is like a swing ... just swayin'.

But the mornings keep on getting darker for some time.

errr, almost Mike! As we (the planet that is) tilt at 23 degrees (or so..) and have an elliptical orbit around the sun, the day length varies from 24hrs minus 20s to 24 hrs plus 30s and daylight after the winter solstice is still pretty mean. witness this morning in the UK when Sunrise where I am was 8.15... (yesterday was 7.45) Oh whither time..

Interestingly, if like me you care more about sunset time than sunrise (I don't get up early enough, clearly), it's been getting lighter for a few days now.

On the other hand, if you get up early then it's still getting darker in the mornings...

Thank goodness for that. But curiously the mornings continue to get darker until next year - an interesting article on the BBC website - http://www.bbc.co.uk/news/magazine-30549149

Yeah, from 1005 hrs on Tues morning in Australia, the days start getting shorter. And hotter. Our hottest time in Victoria is late January, which coincides with the worst fire season. We've had 40% less rain than average , and it's tinder dry . Worried is not the word. I'd love a tropical cyclone to come in in North Queensland, with no major damage, and drop 100mm down here in its aftermath. Only thing absolutely certain about climate change is TOTAL UNCERTAINTY!!

I moved from the eastern side of the central time zone, to the western side of the eastern time zone, and I'm amazed how bright it is in the late afternoons here during winter!

While technically true (though not always) I've just learned two interesting factoids: the time that the sun sets has been getting later since mid-December and the time the sun rises also continues to be later until early January. Apparently it has to do with the fact that days aren't really 24 hours long (tell that to your new AppleWatch accurate to 50 milliseconds). So yes the "days" will be getting longer but early risers face increasing morning darkness for awhile longer. Full explanation here: http://www.bbc.co.uk/news/magazine-30549149

As someone who is both a walkabout photographer and a night owl, rising late and functioning leisurely over an overly long breaky (not the least of which is because of the engaging writing of your humble self and interesting commenters) I find most of my photography this time of year taking place between ISO 800 to 6400, less than optimal. Did I mention that I live in London where daytime is hardly synonymous with sunlight in any case? Bring on March's Equinox!

Thanks to Andy F. for the link to the Beeb's piece, above. I am cheered up a bit knowing that the evenings start getting lighter before the shortest day, but I did not know why.

here in northern indiana, it really does not make a difference what time the sun rises or sets this time of year. Thanks to Lake Michigan it's all clouds all the time.
Is there a Sun?

I was stationed in Lapin Finland, now Lapland and we shot in "available darkness" for the midwinter.

b

where I live in New Zealand official sunrise is currently 5:45am and sunset 9:29pm. Just saying'...

Bryce Lee, at 1/8000th shutter speed, you have the potential to take 8,000 new shots in that extra second. Make good use of it. :-)

It's all about the annalemma, that figure eight thing in the Pacific Ocean on some globes.

It took me over fifty years to realize this: a midnight sun in summer means a midnight full moon in winter! That must be an amazing but chilly sight, watching the moon rise waxing, spin around as bright as can be, then wane and sink again. This never gets much press but that makes it no less true... I think!
