#Coronas are commonly seen around the Sun & Moon but they can also form around bright planets & stars. On 30th Jan '25 I photographed this beautiful #Venus #corona. They form when light from the Sun or Moon is diffracted by water droplets in cloud. Canon 1100D 10-18mm & 300mm lenses, Oxfordshire, UK #AtmosphericOptics #OpticalEffects #Diffraction

#Heiligenschein (bright patch around the head of my shadow) on the very wet grass, taken as the #Moon rose through a thick mist on 22nd October 2024. This is the 1st time I've ever seen this effect from moonlight! It's caused by the #OppositionSurge #OpticalEffects

Some more #AtmosphericOptics from #Oxfordshire on 17th July 2023. We had a nice #22DegreeHalo and really bright #parhelia (#sundogs) which had a bit of a #ParhelicCircle tail. I always love getting aircraft flying near sundogs! #OpticalEffects #IceCrystals #Haloes

On 17th July '23 I saw the best #CircumzenithalArc I've ever seen! There was also a faint hint of a #SupralateralArc which showed up on colour subtracted images. The 1st image has the top of a #22DegreeHalo. Taken from #NorthOxfordshire #AtmosphericOptics #OpticalEffects

Small fragment of a #CircumhorizonArc from #Oxfordshire, UK on Friday 23rd June '23. The Sun has to be higher than 58 degrees for these to form so we don't get many opportunities from the UK. I sat outside for the entire 90mins the Sun was high enough hoping to catch this. The heat was brutal, but I'm so happy even to have caught a fragment! It's only the 2nd time I've photographed one from the UK. #AtmosphericOptics #OpticalEffects

#22DegreeHalo, #9DegreeHalo + #UpperTangent arc forming a partial #CircumscribedHalo Friday 23rd June '23 from #Oxfordshire, UK. #Canon1100D + 10-18mm lens. Colour subtracted images show the detail #AtmosphericOptics #OpticalEffects

#UpperTangentArc (with aircraft flying through it!) Photos taken on 8th April 2023 from Oxfordshire, UK. UTAs are caused by refraction of sunlight through ice crystals #AtmosphericOptics #OpticalEffects

Faint left side #parasalene (#moondog) 18:26 UT 5th Feb '23, from Oxfordshire, UK. Photo taken with a Canon 1100D + 10-18mm lens. It's been a while since I've seen a moondog so I was really happy to see this one #AtmosphericOptics #OpticalEffects

Beautiful #22DegreeHalo visible from Oxfordshire at 12:15 UT 5th February 2023. Photo taken with a Canon 1100D with Canon 10-18mm lens #AtmosphericOptics #OpticalEffects #IceHalo
