No less than eight types of ice halos were observed simultaneously, at the best display over Israel since 2007.

These included the 22°, upper tangent, suncave parry, circumzenithal, supralateral (though partial), sundogs, parhelic circle (large but incomplete) and 120° parhelia (marked with an arrow).

The display lasted for more than 10 minutes, although some of the halos had appeared before and after that peak part – enough to both taking pictures and just enjoying the view.

The whole event took place at 13:00-14:00 local time; with sun elevation ranging from 30° to 27° at peak time.

There were also contrails, and even a small flock of shockwaves was spotted crossing the CZA.

What a day to remember!

A great display indeed. The 46 degrees halo can not have been the supralateral arc however, since it is apart from the circumzenithal arc. Consequently, it must have been [a fragment of] the real 46 degrees ring. The suncave Parry arc is supplemented by the upper Lowitz arc, which can be recognized in the image by its intersection with the left hand wing of the 22 degrees upper tangent arc. So, there were even nine types of ice halos in the display: 22 degs ring, parhelia, upper tangent arc, upper Lowitz arc, suncave Parry arc, circumzenithal arc, 46 degs ring, parhelic circle and 120 degs parhelion.
