We have had lots of rain over the last few days and last night was no exception, until a break in the clouds near sunset appeared and showed of its beauty....

Thanks for the comments guys..

John, UTA stands for:
An upper tangent arc is a halo, an atmospheric optical phenomenon which appears over and tangent to the 22 halo around the sun.

The shape of an upper tangent arc varies with the elevation of the sun; while the sun is low (less than 2932) it appears as an arc over the sun forming a sharp angle. As the sun rises, the curved wings of the arc lower towards the 22 halo while gradually becoming longer. As the sun rises over 2932, the upper tangent arc unites with the lower tangent arc to form the circumscribed halo.

Both the upper and lower tangent arc form when hexagonal rod-shaped ice crystals in cirrus clouds have their long axis oriented horizontally, while otherwise rotated in any direction. This orientation of the crystals also produces other halos, including 22 halos and sun dogs, but a predominant horizontal orientation is required to produce a crisp upper tangent arc. Like many other halos, upper tangent arcs grade from a red inner edge to a blue outer edge because red light is refracted more strongly than blue light(Info from Wiki)
Hope this helps..

Hi all, Over the weekend I got a few shots of an UTA for the first time and on Sunday morning 22 degree Halo.

Anyhow here you go.



And a few of Sunrise
