Our friend Matthew Chin in Hong Kong posted this composite image to EarthSky Facebook earlier this month. Matthew writes a blog on optical phenomena, visible in and around Hong Kong’s skies. This image represents his summing up for 2017:
1) 07/29 Iridescence Cloud
2) 07/08 CZA- Circumzenithal Arc
3) 08/05 Rainbow
4) 07/19 CHA- Circumhorizon Arc

6) 09/24 Twin Rainbow
7) 09/07 Lunar Corona
8 ) 07/13 Lunar Halo
9) 05/12 Sun Halo
10) 07/12 Moondog / Lunar Arhelic Circle
Thank you, Matthew!
