Ice Crystal Halos

  • Thank you for this reminder of a classic (and rare!) observation. It would be interesting to have state of the art intensity vs. solar altitude simulations for the parhelic as well as for the CZA and CHA.

  • Nice pics I like how you can see the infralateral arc and the circumhorizon arc separate from one another in the last pic.

  • In his paper Hutsemekers identifies there 46 halo and circumhorizon arc. I am bound to agree with him. Probably 46 infra is also playing invisible role, conbined with cha. Somebody should make a simutation.

  • Yeah you’re right marko CHA and infralateral arc always touch one another the CHA does not touch 46 halo at that elevation so I guess that must be a very well developed 46 halo because the 22 halo is very bright.
