Odd radius plate display from the Czech Republic

On 4th March Jitka R. from the Czech republic captured this magnificent odd radius display on the Moon. After stacking multiple images, many halo forms showed up - particulary 9°, 18°, 20°, 24° and 35° halos, along with 9° and 24° plate arcs.

It was a case of sublimating cirrus, which could be easily seen on the satellite images.

And I have a question for the halo experts - is it possible that the 9° column arcs are captured, too? Or could it just be a cirrus of a higher quality?
