Details:
Cirrus radiatus is a variety of cirrus clouds, so named due its rayed or striped appearance. Yesterday, as the Sun was setting over the Tijuca Peak in Rio, an interesting group of cirrus radiatus clouds, apparently converging towards the west, prominently adorned the sky. It had been shaped by prevailing winds from the ocean, channeled through the high troposphere by a high pressure cell driven west by the South Atlantic Subtropical High Pressure Center. As they were blowing over Rio, they were producing amazingly long bands of white clouds at high altitudes, giving us the impression to be irradiating from the west. A Canon PowerShot SX60 HS camera was used for the shots, taken around 20:50 UT.
