Louise Emmons sent these two photos of a halo display seen on 9 October, in Noel Kempff national Park North-Eastern Bolivia. The halos are a bright circumscribed halo, a probable 46° infralateral arc and parhelic circle.
"It was one of the most amazing phenomena that I have seen in my life, together with a total solar eclipse with ground waves and an immense fireball", writes Emmons.
The display lasted at least for half an hour. In about 6-8 h it was followed by a strong rain front.
That's a winner. But how mediocre was the mediocre parhelic circle? And are there more photos? Can we simulate the entire display?
