Sun and Moon halo on the same day

Yesterday we had excellent halo conditions here over Östersund, Sweden. During the day I took a photo of the 22° solar halo. And later that night, 10 hours later, when the Moon was in the same position in the sky, I took another shot of a 22° Moon halo taken from the same position. It's quite interesting to see these two halos side by side.

The image below shows the two images merged together. This image was featured as Astronomy Photo Of the Day at NASA

Phil Plait, the Bad Astronomer, did an article explaining the this photo and phenomena more in detail, you can read it here. The photo also appeared on Gizmodo and Peta Pixel.

Here are the two shots separately. The photos were taken 10 hours apart.

  1.   Este mismo efecto lo aprecié esos días -por esta parte de nuestro hemisferio- justo cuando celebrábamos jueves y viernes santo aquí en Sudamerica.
