Spectacular halo, sundogs, upper tangent arc and circumzenithal arc

While at work today, we witnessed a magnificent halo in the sky, accompanied by two brilliantly shining sundogs. We stepped outside to bask in the beauty of the spectacle on the roof of our building.

Moreover, we were fortunate to witness a stunning circumzenithal arc for the very first time.

On our way back home, we were also able to catch a glimpse of an upper tangent arc.  As we were at work, we took the pictures using our smartphones and a Canon Powershot SX740 HS.
