Looking above your head towards the sky just after lunch on Monday, you may have seen rare rainbow clouds.
Rainbow clouds also can be called fire rainbows, even though they have nothing to do with either rainbows or fire.
The rainbow clouds we saw over Echuca on Monday have the scientific name circumhorizontal arcs.
Circumhorizontal arcs are the halo effect you sometimes see around the sun in the height of summer.
The sky appeared to shine with a spectrum of colours when the sunlight reflected off ice crystals suspended in the atmosphere.
For this to occur, the sun has to be high in the sky, just like it is now in summer.
We saw fragments of a halo because the clouds that helped it form were patchy overhead.
Now, this journalist is not a nephrologist who studies clouds, so the descriptions here could be wrong, but we should all look up and enjoy the patterns the clouds make overhead.
