Spring halo outbreak from the Czech Republic

 


The spring of 2022 in the Czech Republic was characteristic of multitude of halo complexes, some dominated by less frequent halo forms. Plenty of those complexes were captured by Jiří Kaňovský, Czechia’s most consistent observer. All halos were observed in Černotín, central Moravia. Most of the pictures shown are stacked frames.

15th of March 

This halo complex lasted a whole day. Apart from more frequent halo forms, some more rare appeared as well, particularly Wegener and Lowitz.

12th of April

The morning started with low-vis odd-radii circular halos – 18° and 23° (not pictured here)
Later stage of the display was dominated by very bright Lowitz arcs. The display ended with “the classics.”

30th of April

Yet another display that spanned the whole day. The display started with circumscribed halo and some odd-radii circular halos as well (9° and a questionable 24°). A weak Wegener was observed, too. The display ended with nicely visible uppercave Parry and high-alt circumzenithal arc.

7th of May

This display was the 3rd time Jiří observed the Wegener arc. This time the arc had nicely visible orange edges which made the arc stand out in the B-R processing. The end of display showed another high-alt circumzenithal arc.


20th of May 

Purely odd-radii halo display with 9°, 18°, 20°, 23°, 24° and 35° circular halos and weaker 23° plate arc.  


23rd of May

High Sun altitude display with circumscribed halo, 46° halo, weak circumhorizontal arc, infralateral arcs and full parhelic circle.
