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

#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

It's quite #foggy again here in North #Oxfordshire tonight, so I have been playing at creating a #WinterSolstice artificial #fogbow, #glory and #BrockenSpectre. Photos taken with a Canon 1100D with 10-18mm wide angled lens. #AtmosphericOptics #OpticalPhenomena #OpticalEffects #Fog #FoggyNight
