New years day full Sun Halo
On New Years Day or otherwise know as 1st of January 2014 while having a group family BBQ to celebrate the start of a new year at Davistown, New South Wales Australia, we witnessed a rare occurrence of a Sun Halo.
What is a sun halo. Well thanks to wikipedia “it is an optical phenomenon produced by ice crystals creating colored or white arcs and spots in the sky. Many are near the sun or moon but others are elsewhere and even in the opposite part of the sky. They can also form around artificial lights in very cold weather when ice crystals called diamond dust are floating in the nearby air. They are produced by the ice crystals in cirrostratus clouds high (5–10 km, or 3–6 miles) in the upper troposphere. The particular shape and orientation of the crystals is responsible for the type of halo observed. Light is reflected and refracted by the ice crystals and may split up into colors because of dispersion. The crystals behave like prisms and mirrors, refracting and reflecting sunlight between their faces, sending shafts of light in particular directions.”
This was the first time I had seen one so, like all things you take a photo. Now trying to take a photo directly into the sun is no easy feat. For one it’s hard enough looking into the sun on a hot summers day at lunchtime around 1pm, let alone being able to seen anything in camera’s LCD screen. Anyway after a few tweaks of the exposure the below was my best photo to show the sun halo.
Have you seen a sun halo and if so when and where have you seen one?
How do you replay a Google doodle
I jumped on to Google today and was presented with the Google doodle for Maria Gaetana Agnesi.
Honestly not that I had heard of her before that I remember anyway. Sorry Year 7 maths teacher. But the doodle was interesting in the way the curve was being generated with the circle and the triangles trans versing across the image.
Now the animation runs fairly quickly and at first glance in that 3 seconds it’s a little hard to pick up everything that is going on with the doodle.
So i thought how do you replay a Google doodle. Now there is no button to replay the doodle and if you click on the Google doodle itself it takes you to Google’s search results for “Maria Gaetana Agnesi”
Answer: So the easiest way to replay the Google doodle is to press Ctrl + F5 which will force a full refresh of the home page. A F5 by itself does not work.
It would be a nice feature for Google to add a button or something to be able to replay the animated Google doodles.
