Ice Halos by Moonlight
An almost full moon on April 15 brought these luminous apparitions to a northern spring night over Alberta Canada. On that night, bright moonlight refracted and reflected by hexagonal ice crystals in high clouds created a complex of halos and arcs more commonly seen by sunlight in daytime skies.

30th Aug '23 was an amazing night for lunar #AtmosphericOptics around the #PerigeeFullMoon! Lunar #22DegreeHalo #CircumzenithalArc + the best #paraselenae (#moondogs) I've seen, both showing #ParaselenicCircle fragments! Canon 1100D + 10-18mm lens. Click image to view full size

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

#22DegreeHalo + much less common #SupralateralArc from Oxfordshire, UK 15/03/23 ?faint #CircumzenithalArc also. Photos from 08:55-09:55UT when Sun altitude was 21-28 deg. Colour subtraction
really brought out the detail. Canon 1100D + 10mm lens #AtmosphericOptics -

Clouds cleared off for a while this morning leaving just enough ice in the atmosphere to put on a show! I saw a rainbow reflected in multiple car windows and at first thought it was some kind of interplay between sunlight and automotive glass. Then I looked up and saw the brilliant circumzenithal arc high overhead! Note, too, in the photo a sundog to the left of the overexposed Sun. -- December 20, 2023 just before noon in Akron, Ohio. #rainbow #solararc #circumzenithalarc #atmospheric
